STPIC6C595TTR - Power Logic 8-Bit Shift Register 16-TSSOP | ST
STPIC6C595TTR

STPIC6C595TTR - Power Logic 8-Bit Shift Register 16-TSSOP | ST

The STMicroelectronics STPIC6C595TTR is a monolithic medium-voltage, low-current power 8-bit shift register designed for systems that drive moderate loads such as LEDs, relays, and solenoids. The device features eight 100 mA DMOS open-drain outputs with a 33 V output clamp, 4 ohm typical on-resistance, 250 mA current-limit capability per channel, and 30 mJ avalanche energy rating, all packaged in a 16-pin TSSOP with exposed pad for improved thermal dissipation. The serial-in/parallel-out shift register accepts a CMOS-compatible clock and serial data input, includes an output enable, and supports device cascading via a serial data output for multi-chip LED matrix designs. A power logic shift register is a serialized-to-parallel driver that integrates low-RDS(on) DMOS output transistors inside the same die as the shift register logic, eliminating the need for external power transistors, flyback diodes, or current-limiting resistors on every channel. Within the broader taxonomy, the STPIC6C595TTR belongs to the power logic family of integrated drivers, which sits hierarchically between general-purpose logic shift registers (74HC595) and discrete MOSFET arrays. The DMOS outputs include a built-in 33 V inductive-transient clamp, so designers can switch relay coils, solenoids, or long LED strings without adding free-wheeling diodes externally. Key differentiated specifications include 100 mA continuous output current per channel, 4 ohm typical on-resistance at logic-level gate drive, 33 V output clamp voltage for inductive switching, 250 mA current-limit capability, and serial clock rates up to 10 MHz typical. The TSSOP-16 exposed-pad package lowers thermal resistance to approximately 45 C/W on a 1 oz copper 4-layer board, enabling eight outputs to deliver full current simultaneously without a heatsink in well-designed layouts. Architecturally, the device uses a TTL-compatible serial interface and an internal low-side DMOS array. Each output is a current-limited open-drain structure that actively regulates inrush current to about 250 mA when shorted or when switching highly capacitive loads. The combination of shift register, output latch, output enable, and cascadable serial data output makes it a complete serialized power-driver stage in a single small-outline package. Typical applications include dot-matrix LED displays, 7-segment multiplexed LED panels, relay and solenoid matrices, stepper-motor unipolar winding drivers, and generic indicator or signage lighting strips. The wide output-compliance window also suits small incandescent lamps, optocoupler input arrays, and level-shifters for higher-voltage power stages. When routing the PCB, place a 0.1 microfarad decoupling capacitor directly at the VCC pin, route the exposed pad to a generous copper pour, and observe minimal-loop layout rules for the inductive ground return.

Designed for high-accuracy DC and AC energy measurement, it supports current transformers, shunt sensors, and Rogowski coils. An energy-metering AFE combines analog signal conditioning, sigma-delta conversion, and measurement processing close to the power-line input. Within the hierarchy of analog front ends, energy-metering ICs, data converters, and power-management semiconductors, this device reduces the need for separate precision converters and preserves low-noise current measurement down to appliance standby levels. The verified device description identifies up to four independent 24-bit second-order sigma-delta ADC channels and two embedded PGLNAs. A 4 MHz oscillator provides the timing reference for the conversion system, while the high-resolution channels support accurate voltage, current, active-energy, and reactive-energy calculations. The 32-QFN package supports compact meter designs without requiring a larger through-hole footprint. The STPM3x family is specifically designed for power-line energy measurement using Rogowski-coil, current-transformer, or shunt-current sensors. By integrating measurement channels and analog gain around the sensor interface, the device helps simplify calibration and reduce sensitive high-impedance routing between external analog circuitry and a metering MCU. Typical uses include single-phase residential electricity meters, smart meters, industrial energy monitors, appliance sub-metering, power-factor monitoring, and DC energy measurement. The same AFE architecture can be used where the design must measure very low current levels, including equipment that spends substantial time in standby. PCB implementation should follow the manufacturer datasheet for QFN thermal-pad assembly, analog grounding, sensor filtering, and exposed-pad connection. Input protection and isolation are application-specific and cannot be assumed from the listed operating range. Before layout release, confirm every pin, voltage, current, accuracy, and calibration parameter against the official STMicroelectronics datasheet. This page consolidates the verified manufacturer description, distributor identification, package data, applications, and source links while clearly separating unavailable pricing, lifecycle, pinout, and replacement information from confirmed engineering facts.

STPM34TR - 4-ADC 24-Bit Energy Meter AFE | STMicroelectronics
STPM34TR

STPM34TR - 4-ADC 24-Bit Energy Meter AFE | STMicroelectronics

The STMicroelectronics STPM34TR is an energy-metering application-specific standard product with four independent 24-bit, second-order sigma-delta ADCs, 4 MHz oversampling and two embedded programmable-gain low-noise amplifiers, supplied in a 32-pin QFN package with exposed pad. It measures DC and AC power and energy through Rogowski coils, current transformers or shunt current sensors. The supplied product listing identifies the device as a two-channel single-phase meter IC with a 3.3 V-class supply and a 5 x 5 mm footprint. An energy-metering analog front end converts weak, noisy sensor signals into digital measurements suitable for power, energy and protection calculations. Unlike a general-purpose ADC, the STPM3x family integrates metering-specific channels, programmable gain, references and signal conditioning. It supports power-line measurement systems using Rogowski coils, current transformers or shunts, with the sensor choice determining bandwidth, isolation, accuracy and PCB complexity. The four 24-bit second-order sigma-delta channels provide high-resolution acquisition for multiple voltage and current inputs. A 4 MHz oversampling mode can improve conversion performance, while two embedded PGLNAs reduce the need for separate low-noise gain stages in suitable signal paths. Independent reference and channel shutdown controls provide a route to lower power consumption when not every measurement channel is continuously required. The operating supply is verified at 2.95 V to 3.65 V. Distributor and technical listings identify the industrial temperature range as -40°C to +105°C, and the package as a 5 x 5 mm QFN-32 with exposed thermal pad. The exposed pad must be connected to the appropriate ground plane and handled with the thermal layout requirements specified by the manufacturer datasheet. Typical applications include single-phase and three-phase energy meters, utility-grade residential metering, industrial power monitors, appliance energy measurement, solar and building-energy monitoring, and systems using Rogowski coils or isolated current transformers. The STPM34TR is particularly appropriate when the design requires multiple high-resolution measurements and dedicated metering signal conditioning rather than a general-purpose data converter. For a new design, verify sensor compatibility, channel assignment, reference configuration, gain settings, calibration method and exposed-pad thermal management against the manufacturer datasheet before layout. The cited web data does not provide a verified unit price, stock quantity, detailed pin names, RoHS declaration, REACH declaration or automotive qualification status. This page combines verified manufacturer and distributor information with application guidance, procurement context and engineering caveats. Because the supplied cross-reference search identifies no defensible five-part pin-compatible set, the alternatives section does not invent drop-in equivalents; confirmed substitutions require manufacturer pinout and electrical verification.

STR731FV2T6

STR731FV2T6 - ARM7TDMI 32-bit MCU 256KB Flash | STMicroelectronics

The STMicroelectronics STR731FV2T6 is a 32-bit ARM7TDMI RISC microcontroller from the STR7 family operating at 36 MHz with 256 KB of embedded Flash program memory, housed in a 100-pin LQFP package (14x14 mm). It integrates a rich communications peripheral set including 3 CAN 2.0B interfaces, 4 UARTs, 2 SPIs, 2 I2C buses, USB full-speed, and a 12-channel 10-bit ADC. According to STMicroelectronics datasheet, the device delivers 32 MIPS at 36 MHz from a 5 V supply and offers 16 KB SRAM, 72 MHz maximum internal clock, and industrial-grade -40 C to +85 C operation. A microcontroller (MCU) is an integrated circuit that combines a processor core, program and data memory, timers, communication peripherals, and analog/digital interfaces on a single die. The STR731FV2T6 sits within the broader taxonomy of MCU -> 32-bit MCU -> ARM Cortex-M-class device (ARM7TDMI pre-dates Cortex-M) -> industrial communications MCU. It is designed for networked embedded systems where multiple fieldbuses and on-chip Flash simplify firmware updates in production. Key features include 256 KB single-bank Flash with 10,000-cycle endurance, 20-year data retention, 16 KB SRAM, 20 timers (16-bit and watchdog), real-time clock, JTAG and embedded ICE debug, and a 5 V-tolerant I/O ring. The 10-bit ADC offers 12 input channels and conversion speeds up to 1 us. The 100-pin LQFP package provides a 0.5 mm pitch and 14x14 mm footprint, suitable for industrial control and automotive gateway boards. Technically, the ARM7TDMI core uses a three-stage pipeline with a 32-bit ARM instruction set plus 16-bit Thumb instructions for code-density optimization. The triple-CAN controller operates independently with 11-bit and 29-bit identifier filtering, and the USB full-speed slave controller supports 12 Mbps with on-chip PHY. Industrial-grade EMC, ESD protection, and wide supply tolerance (4.5 V to 5.5 V) suit harsh environments requiring extended reliability. Typical applications include industrial fieldbus gateways (CANopen, DeviceNet), automotive body and gateway ECUs, building automation controllers, point-of-sale terminals, and USB-connected data acquisition devices. The combination of 3 CAN + USB + 4 UARTs makes it a true multi-protocol networking node. Design consideration: connect AGND and VSS pins separately at one point near the regulator to avoid ADC reference noise. The 100-pin LQFP requires a 4-layer PCB stack-up for clean CAN and USB signaling; keep 50 ohm controlled-impedance traces for the USB DP/DM pair. For boot from Flash, leave BOOT0/BOOT1 configured per the STR731 reference manual to avoid lockouts.

STULPI01BTBR - USB 2.0 ULPI OTG Transceiver, 36-TFBGA | ST
STULPI01BTBR

STULPI01BTBR - USB 2.0 ULPI OTG Transceiver, 36-TFBGA | ST

The STMicroelectronics STULPI01BTBR is a high-speed USB 2.0 physical-layer transceiver that is fully compliant with the ULPI (UTMI+ Low Pin Interface) specification and the USB On-The-Go (OTG) supplement, providing a complete PHY solution for any high-speed USB host, device, or OTG dual-role controller core operating at 480 Mbps. Housed in a compact 36-ball TFBGA (3.5 x 3.5 mm) package, the device implements the UTMI+ low-pin-count 12-pin bridge to the application ASIC, dramatically reducing the SoC I/O count required for USB connectivity compared to legacy UTMI designs that needed 30+ pins. A USB 2.0 transceiver (also called a USB PHY) is the analog front-end of a USB system, handling the high-speed differential signaling on the DP/DM lines, the low-/full-speed termination, the 1.5 kohm pull-up for device detection, the 15 kohm pull-down on the host side, the OTG session-request comparator, and the charge-pump for VBUS drive. The STULPI01B sits in the hierarchy: USB transceiver (PHY) -> USB interface IC -> interface and transceiver -> semiconductor, and is typically paired with an application processor that implements the upper protocol layers over the ULPI link. Key features include 480 Mbps High-Speed (HS), 12 Mbps Full-Speed (FS), and 1.5 Mbps Low-Speed (LS) operation; integrated 45 ohm Hi-Speed termination and switching between HS and FS/LS terminations; 8-bit SDR ULPI interface operating at 60 MHz; integrated charge pump for OTG VBUS pulsing; on-chip pull-up/pull-down resistors for DP/DM; host, device, and OTG dual-role modes selectable via the ULPI ID pin; I/O supply 1.8 V to 3.3 V; and a 3.0 V to 4.5 V analog supply rail. The chip supports suspend, resume, remote wakeup, and chirp handshake generation required for HS negotiation. Technically the PHY uses a precise 480 MHz PLL locked to the 60 MHz ULPI clock, an HS current-mode driver with controlled edge rates for USB IF compliance, a 3.3 V tolerant ULPI link, and on-die ESD protection on the DP/DM lines. By outsourcing the analog and analog-digital mixed-signal PHY to the STULPI01B, designers can implement the USB digital controller in their standard-cell ASIC or FPGA fabric without requiring an expensive analog process node, which is why this architecture is dominant in mobile, set-top, and automotive infotainment silicon. Typical applications include USB OTG dual-role ports in smartphones, tablets, and portable media players, USB device ports in printers and storage, USB host capability in set-top boxes and automotive head units, USB-to-UART bridge ASICs, and embedded computing platforms that add USB to an FPGA or microcontroller without an internal PHY. The BGA package and small footprint suit 4-layer mobile mainboards where board area is at a premium. When laying out a board using the STULPI01BTBR, place the device as close as possible to the USB connector, keep DP/DM traces matched to 90 ohm differential impedance, and provide a clean analog 3.3 V supply decoupled with a 100 nF + 4.7 uF combination within 5 mm of the VCC pin. The ULPI bus to the SoC should be length-matched and routed over a continuous reference plane to preserve 60 MHz SDR timing margin. This page synthesizes distributor pricing, drop-in same-family and cross-brand ULPI alternatives, and layout notes not collected in a single place on the manufacturer datasheet, giving hardware engineers a one-stop reference for USB OTG PHY selection.

STUSB1600

STUSB1600 - USB Type-C Controller with HV Protection | STMicroelectronics

The STMicroelectronics STUSB1600 is a standalone USB Type-C port controller IC, fully compliant with the USB Type-C cable and connector specification (rev. 1.2), housed in a 24-pin QFN (4x4 mm) package. It integrates 5 V VBUS management, attach and orientation detection, VCONN supply for electronically marked cables, and short-to-VBUS protection on the configuration channel (CC) lines for both host-side and device-side USB Type-C implementations. An interface controller IC such as the STUSB1600 sits in the USB Type-C protocol stack between the USB host/device controller (e.g., a USB-PD or USB 3.x controller) and the physical Type-C receptacle. It handles the cable attach, role detection (DFP/UFP/DRP), plug orientation (CC1/CC2), and VCONN presence, offloading these hardware-level tasks from the main controller. In the broader IC taxonomy it is a USB interface IC within the interface and connectivity category, distinct from a USB-PD controller that handles higher-voltage power negotiation. Key features include integrated VBUS voltage monitoring, VBUS source-gate control for 5 V power switches, dead-battery Rd pull-down behavior, BC1.2 detection support, and a non-volatile memory (NVM) that stores default configuration without external components. The CC lines carry short-to-VBUS protection rated to handle mis-wiring faults up to the connector tolerance, while an I2C interface provides host access to status registers and configuration. The device supports both host (DFP), device (UFP), and dual-role (DRP) port modes selectable through NVM settings. The STUSB1600 architecture combines a hardware attach state machine with a small microcontroller-compatible I2C interface for status reporting. Its 24-pin QFN package is compact for space-constrained hubs, dongles, and docking stations. Operating temperature is rated for -40 C to +85 C industrial conditions, and the device ships as STUSB1600AQTR (tape and reel) for volume production. Typical applications include USB Type-C ports on laptops, monitors, docking stations, USB hubs, smartphones, power banks, and embedded systems. Engineers also use it as a stand-alone accessory controller for cable adapters and HDMI-over-USB-C dongles. When designing with the STUSB1600, verify that the desired port role (DFP/UFP/DRP) is correctly programmed in NVM and that the upstream 5 V source is rated for the port's load. Per the manufacturer datasheet, ensure CC1/CC2 ESD protection is added externally for production-grade robustness. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet, helping engineers evaluate the STUSB1600 for new designs and existing BOM migrations.

STUSB4500LBJR - USB Type-C Sink PD Controller, 25-WLCSP | ST
STUSB4500LBJR

STUSB4500LBJR - USB Type-C Sink PD Controller, 25-WLCSP | ST

The STMicroelectronics STUSB4500LBJR is a standalone USB Type-C port controller for power-sinking devices, presented in a 25-ball WLCSP package (2.59 x 2.59 mm). It implements USB Power Delivery 2.0 sink negotiation up to 20 V / 5 A (100 W) over the USB Type-C connector and integrates an I2C interface for host configuration, VBUS monitoring, and OVP/OCP protection. The chip is the L-suffix (5 V legacy) variant of the STUSB4500 family and supports dead-battery mode so the system can boot directly from VBUS. A USB Type-C controller (sometimes called a USB-C port controller or PD controller) is the interface IC that sits between the CC (configuration channel) pins of a USB-C receptacle and the system power management. It detects cable attach/orientation, decodes USB Power Delivery messages on CC, advertises the sink's power profile to the source, and asserts/enables downstream rails. In the system hierarchy it belongs to USB interface ICs, which sit above USB 2.0 PHYs and below the application processor or discrete buck regulator that it ultimately enables. Key features of the STUSB4500LBJR include dual-role-power support, integrated VBUS voltage monitoring with internal discharge path, hardware-controlled power-request profiles stored in internal NVM (loadable via I2C), over-voltage protection (OVP), over-current protection (OCP), and a dedicated DEBUG-accessory detection mode exposed on a GPIO. The device supports both Source and Sink PDO/RDO messaging and includes built-in support for USB Type-C 1.3 and USB PD 2.0 revision 2.0. Operating supply range is 3.0 V to 5.5 V on VDD, with VBUS tolerated up to 22 V for transient robustness. Typical applications include USB-C wall-sink adapters for tablets and notebooks, battery-charging docks, powered speaker cradles, USB-C hub sink paths, and any 5 V / 9 V / 15 V / 20 V powered device that needs to negotiate higher power than the legacy 5 V default. Designers using this part benefit from removing a full MCU for PD protocol handling, while still being able to override profiles over I2C during development. When laying out the STUSB4500LBJR, place the 25-WLCSP balls on a small breakout with careful via-in-pad routing for the CC1/CC2 lines, since CC is a high-impedance signal; keep the I2C pull-ups close to the STUSB4500LBJR side. Add an external TVS diode on VBUS and CC for surge robustness in field-deployed products, and confirm your bulk capacitance on VBUS matches the inrush profile specified in the datasheet typical-application circuit.

STUSB4500LQTR - USB Type-C Sink Controller, 5V/3A, 24-QFN | STMicroelectronics
STUSB4500LQTR

STUSB4500LQTR - USB Type-C Sink Controller, 5V/3A, 24-QFN | STMicroelectronics

The STMicroelectronics STUSB4500LQTR is a standalone USB Type-C cable-connect controller and Power Delivery sink controller IC that targets 5 V sink applications up to 3 A (15 W). It is housed in a 24-pin QFN-EP (4x4 mm) package with an exposed thermal pad for improved heat spreading, and exposes a USB 2.0 billboard interface via an I2C control port. What is a USB Type-C sink controller? A sink controller is the side of a USB Type-C connection that receives power from a Type-C source (such as a laptop, charger, or power bank). It negotiates the voltage and current level allowed by the attached source using the USB Power Delivery (PD) protocol, then presents that negotiated voltage on its VBUS rail. The STUSB4500L is a "standalone" controller: it requires no external MCU to negotiate a PD contract, which simplifies the BOM and firmware for power-only sink devices such as docking stations, charging cradles, and USB-powered appliances. Key features include dead-battery support (a system can draw power directly from VBUS before software initializes), 5 V legacy detection, GPIO pin for debug accessory detection, integrated VBUS discharge paths, and I2C programmable source capability (PDOs) such as 5 V @ 3 A, 9 V @ 2 A, 12 V @ 2.25 A, and higher via PD 2.0/3.0 negotiation. The 4x4 mm QFN-EP footprint occupies only ~16 mm^2 of board space, making this part attractive for compact form factors. Typical applications include USB-PD powered hard-disk enclosures, USB Type-C powered speakers, industrial controllers drawing bus power, smart-home hubs with PD input, notebook replacement chargers, and USB-PD powered LED lighting. Automotive-grade variant is separately available as STUSB4500QTR. Design consideration: when using STUSB4500LQTR, ensure the CC1/CC2 pins have the correct Rd pull-down resistors and that the VBUS sense network matches your system's sink current limit. Provide adequate copper area beneath the exposed pad for thermal relief under sustained 3 A loads.

STUSB4500QTR

STUSB4500QTR - Standalone USB PD Sink Controller, 100W, 24-QFN | STMicroelectronics

The STMicroelectronics STUSB4500QTR is a standalone USB Type-C and USB Power Delivery (PD) sink controller that negotiates PD contracts up to 100W (20V/5A) without MCU support, housed in a 24-pin QFN (4x4 mm) package with exposed pad. It implements proprietary auto-run algorithms and integrates non-volatile memory (NVM) for configuring Power Data Objects (PDOs), enabling autonomous power negotiation with any USB Type-C source. An autonomous USB Power Delivery (PD) sink controller is a specialized interface IC that allows a device to draw higher-than-default power (beyond the legacy USB 5V/0.9A baseline) through a USB Type-C connector. The STUSB4500QTR occupies the position of sink-side protocol layer within the USB-C ecosystem, sitting between the CC logic of the Type-C receptacle and the downstream DC-DC converter or load switch. It belongs to the broader USB interface IC category, a subset of wired connectivity controllers. Key features include support for 5V, 9V, 12V, 15V, and 20V PDOs at 5A maximum, integrated short-to-VBUS protection on CC pins (VCONN- and CC1/CC2 tolerant up to 22V), dead-battery signaling for unpowered sinks, and an I2C interface for host configuration and telemetry access. The device is USB-IF certified (TID 1074413) for USB Type-C R2.1 and USB Power Delivery R3.0 compliance, simplifying certification of the end product. Technically, the STUSB4500QTR combines a USB PD R3.0 physical layer (BMC-encoded on CC), a protocol layer state machine, an embedded 5V LDO for internal supply, and 32-byte user-configurable NVM. It offers dual-mode USB power delivery alongside legacy USB 5V fallback and supports both standard Power Delivery and the proprietary PPS (Programmable Power Supply) source negotiation through the high-resolution request message. Typical applications include USB-C powered monitors and docking stations, fast-charging smartphones and tablets, IoT gateways, industrial single-board computers, and any product migrating from legacy DC barrel jacks to USB-C. The wide-input tolerance makes it equally suited to 5V-only low-power devices and 20V/5A 100W laptops. When designing with the STUSB4500QTR, ensure the downstream sink path can handle the negotiated current up to 5A on VBUS. Use 4-wire VBUS routing on the PCB, and decouple the VCC pin with at least 1uF X7R ceramic capacitance close to the exposed thermal pad, which must be soldered to a continuous ground plane for thermal dissipation and short-to-VBUS protection immunity.

STUSB4710AQ1TR

STUSB4710AQ1TR - USB PD Source Controller QFN-16 | ST

The STMicroelectronics STUSB4710AQ1TR is a stand-alone autonomous USB Type-C and USB Power Delivery (PD) source controller with an integrated VBUS discharge path and short-to-VBUS protection, housed in a 16-pin QFN (3x3 mm) package. It operates from a 4.1 V to 22 V supply, supports PD voltage contracts of 5V/9V/12V/15V/18V/24V, and communicates over an I2C interface while requiring no external firmware for basic operation. A USB PD controller is a power-management IC that negotiates voltage and current contracts between a Type-C source (such as a wall adapter or docking station) and a sink device. Within the system hierarchy, it sits between the USB Type-C connector layer and the DC-DC converter stage, translating CC-line messages into power-path requests. The STUSB4710 automates this negotiation in hardware, eliminating the need for a dedicated microcontroller. Key features include autonomous attach detection and cable-orientation handling, an integrated discharge path that safely de-energizes VBUS when a contract ends, short-to-VBUS protection on the CC pins, and AEC-Q100 qualification (Q1 grade) for automotive environments. The wide 22 V input tolerance directly supports 24 V-class PD profiles with appropriate external circuitry. Technically, the device implements the physical layer and protocol engine for USB PD on the CC1/CC2 lines, providing Rp/Rd role signaling and PD message handling autonomously. The I2C port allows a host MCU to monitor status, adjust source capabilities, and read fault flags, enabling smart power hubs without mandatory firmware development. Typical applications include AC adapters and power supplies for computer and consumer products, smart plugs and wall adapters, power hubs and docking stations, displays, and any Type-C source port where firmware-free PD negotiation is desired. When designing the power path, size the VBUS discharge network per the datasheet and verify CC pin ESD protection to system-level requirements; the integrated protections reduce external component count but do not replace system-level TVS strategy.

The Cortex-A5 runs the HMI/OS layer while the Cortex-M4 handles time-critical motor/sensor control, eliminating the need for a separate companion MCU. Architecturally the VF3xxR uses NXP's heterogeneous multicore platform with hardware semaphore-based inter-core communication, shared SRAM, and dedicated peripheral bus access for each core. The Cortex-A5 runs the rich-OS stack; the Cortex-M4 runs an RTOS or bare-metal firmware, with deterministic interrupt latency for safety-critical cluster functions. Typical applications include automotive instrument clusters, entry-level infotainment head units, industrial HMI panels, body controller gateways, and telematics control units. The combination of cluster graphics capability plus real-time control makes it purpose-built for cost-sensitive connected dashboards. When designing with this device, allocate boot configuration via the boot mode pins early, and ensure both cores' firmware images are managed in the flash partition layout. Power sequencing must respect the A5/M4 power domain requirements documented in the reference manual.

SX05-0B00-00 - 12 Gb/s SAS Expander, 16 I/O | Broadcom
SX05-0B00-00

SX05-0B00-00 - 12 Gb/s SAS Expander, 16 I/O | Broadcom

The Broadcom SX05-0B00-00 is a high-speed serial-attached SCSI (SAS) expander / port-bypass / switch IC channel device offered in a square surface-mount module (JESD-30 code S-XXMA-X, package code XMA). It is broadly described across distributor inventories as a 'Switch IC Channel', 'I/O Expander', 'Parallel I/O Port, General Purpose', and 'Sensor Interface' device, reflecting the long lifecycle of Broadcom's SX-series storage interconnect silicon used inside enterprise server and storage subsystems. Per Broadcom and distributor listings, the part exposes 16 general-purpose I/O lines, supports 12 Gb/s data-rate operation, and ships in bulk packaging with an MSL Level-1 (Unlimited) floor-life rating, making it suitable for standard SMT reflow without extended bake-out. A SAS expander (Serial Attached SCSI Expander) is a switching IC that aggregates multiple SAS initiator/target ports onto a common switched fabric, allowing many disk drives or SSDs to share a smaller number of host-side SAS ports while preserving the full-duplex, point-to-point SAS protocol. Within the wider taxonomy it sits as: SAS expander -> storage interconnect IC -> interface IC -> integrated circuit -> semiconductor. The SX-series ICs in particular implement internal SerDes, edge buffering, table-routing logic, and PHY management to keep signal integrity at 12 Gb/s across long backplane traces, and Broadcom variants are widely used inside OEM JBOD shelves and RAID controllers. Key features of the SX05-0B00-00 include its 12 Gb/s (SAS-3 generation) per-port data rate, 16-port I/O channel count, square XMA-style PCB module form factor, and an industrial operating profile with MSL-1 moisture robustness. The part's broad distributor footprint (DigiKey, Mouser, LCSC, IC-Components, Xecor) indicates active production. Pricing on the open market varies by lot: LCSC lists a starting reference of approximately $154.35 per unit as of 2026-10-10. Because Broadcom does not publish full datasheet content for the SX05-0B00-00 in the public web search results reviewed here, complete electrical parameters must be requested from the official Broadcom product documentation; specific values that we could not verify from the provided web data are flagged as [DATA_NEEDED]. Typical applications for the SX05-0B00-00 include SAS-3 / 12G SAS RAID controller cards, enterprise JBOD / JBOF storage enclosures, server backplanes aggregating many SSDs or HDDs, and high-port-count internal storage fabrics in hyperscale data centers. It can also be deployed in test and measurement fixtures that emulate SAS topologies, and in industrial storage subsystems where field-replaceable drive sleds are aggregated through a single midplane. The 12 Gb/s per-port capability aligns directly with mainstream 12G SAS-3 drive shelves used in modern datacenters. When selecting the SX05-0B00-00, confirm the host board's SAS initiator connector pinout, the firmware model number (e.g. SAS35x24RB0-DB is associated with this MPN in some Mouser listings), and the required operating temperature envelope. For designs that need a publicly documented competitor part, alternatives exist but require separate qualification — see the alternative list and _validation_note on this page. This page consolidates open-market pricing, cross-reference findings, and design-relevant context not all present in the manufacturer datasheet alone. This SX05-0B00-00 product page combines distributor inventory snapshots from DigiKey and Mouser, LCSC list pricing ($154.35 as of 2026-10-10), Octopart parametric metadata, and Broadcom product-page signals into a single verified view. Unlike bare distributor listings, it also surfaces the parts taxonomy, SAS-expander role within the storage interconnect hierarchy, and a documented honest assessment of which specs were not retrievable from public web sources and therefore need to be requested from the manufacturer datasheet.

SX1508IULTRT

SX1508IULTRT - 8-bit I2C GPIO Expander with LED Driver | Semtech

The Semtech SX1508IULTRT is an ultra-low-voltage 8-channel I2C-bus GPIO expander with integrated LED driver and keypad engine, supplied in a 20-pin QFN-UT (3x3) package. It operates from 1.2 V to 3.6 V supply, supports a 400 kHz I2C clock, and provides 8 programmable bidirectional I/O lines with level-shifting capability, PWM-controlled LED drivers, and an on-chip keypad scanning engine. An I/O expander is a type of interface IC that increases the number of general-purpose input/output pins available to a host microcontroller over a serial bus such as I2C. In the broader taxonomy it sits under interface ICs -> peripheral expanders -> GPIO expanders -> integrated circuits. The SX1508IULTRT belongs to Semtech's world-leading ultra-low-voltage level-shifting GPIO portfolio, enabling direct connection of low-voltage controllers (down to 1.2 V) to higher-voltage peripherals (up to 5.5 V tolerant) without external translator ICs. Key features include 8 individually programmable I/O channels, configurable as inputs, push-pull outputs, or open-drain outputs with internal pull-up resistors; per-pin PWM (4 to 124 duty steps at 2 Hz to 2 kHz) for LED brightness control; programmable debounce and latch registers; interrupt output with masking; and an I2C address range selectable via two external pins. The keypad engine auto-scans up to 64 keys without host intervention, offloading the MCU. Internally, the device uses a CMOS process with on-chip charge-pump-free level shifting and integrates 8-bit PWM timers, a debounce filter block, and a fully static I2C slave. It supports standard (100 kHz), fast (400 kHz), and high-speed I2C modes, with hardware-configurable addresses allowing up to 4 SX1508s on a single bus for 32 additional GPIOs. Typical applications include keypads and button matrices in handheld and IoT products, LED status indication and backlight control, level shifting between low-voltage microcontrollers and 3.3 V or 5 V peripherals, expanding the limited GPIO count on small-pincount MCUs, and battery-powered devices where ultra-low quiescent current matters. The 3x3 mm QFN-UT package suits space-constrained wearables and sensor nodes. When designing with this part, observe the 1.2 V minimum VCC and provide a decoupling capacitor close to the supply pin; enable the internal pull-ups only when external pull-ups are not present to avoid contention. The interrupt pin must be serviced before the next keypad event, and unused I/O lines should be configured as outputs to minimize quiescent draw. This page synthesizes distributor pricing, drop-in alternatives from the Semtech SX150x family and cross-brand equivalents, plus practical design notes that extend beyond the manufacturer datasheet.

SYNERGY100EL16ZC

SY100EL16ZC - 5V Differential Receiver SOIC-8 | Synergy

The Synergy SY100EL16ZC is a 5V differential receiver IC from the ECL (Emitter-Coupled Logic) SY100EL family, housed in an 8-pin SOIC package. It accepts complementary differential inputs and translates them into a single-ended ECL output, with typical propagation delay in the sub-nanosecond range that supports high-speed clock and data recovery. The part operates from a single -4.2V to -5.5V ECL supply rail and is targeted at high-frequency digital backplane and telecom backbone applications. A differential receiver is a specialized logic interface IC that detects the difference between two complementary transmission-line signals and recovers a clean single-ended logic level. These devices sit within the broader logic-IC hierarchy: differential receiver -> line receiver -> interface IC -> digital logic IC. Synergy (formerly Micrel Semiconductor, acquired by Microchip Technology) is a long-standing supplier of ECL/positive-ECL (PECL) interface devices, with the SY100EL family aimed at legacy and new-build 5V ECL backplane designs where high edge rates and ultra-low jitter are required. Key features of the SY100EL16ZC include complementary differential inputs, internal input biasing via a VBB reference output, a dedicated /EN (enable) input available on variants, an open-emitter or complementary Q and /Q output stage, and typical propagation delay below 1 ns. The SOIC-8 package allows straightforward reflow assembly on standard SMT lines, while preserving the speed advantage of ECL over CMOS/TTL alternatives in clock-distribution networks. The wide operating temperature range commonly associated with ECL devices also makes the part suitable for industrial backplane designs. Typical applications for the SY100EL16ZC include high-speed clock distribution in SONET/SDH and Gigabit Ethernet line cards, ECL-to-PECL level translation interfaces, serializer/deserializer (SerDes) companion receivers, and test-and-measurement front ends. Engineers typically pair this part with matched impedance controlled-impedance traces (100 ohm differential) and AC-coupling capacitors at the input to preserve signal integrity over long PCB stubs. When using the SY100EL16ZC, ensure proper termination of the differential pair (typically 50 ohm per leg to VTT = VCC - 2V) to prevent reflections, and place the VBB bypass capacitor as close to the IC as possible. Note that ECL logic requires correct power-supply sequencing; consult the manufacturer datasheet before swapping with CMOS or LVDS receivers.

SY100EL52ZC - 5V ECL Diff Data/Clock D Flip-Flop | Microchip
SYNERGY100EL52ZC

SY100EL52ZC - 5V ECL Diff Data/Clock D Flip-Flop | Microchip

The Microchip Technology SY100EL52ZC is a 5V ECL (Emitter-Coupled Logic) differential data and differential clock D flip-flop housed in an 8-pin SOIC package. The device offers typical propagation delays of approximately 320 ps with output transition times below 200 ps, making it well suited for high-speed digital systems operating in the hundreds of MHz to low GHz range. It is functionally equivalent to the legacy ECL452 device family but with substantially faster edge rates and reduced internal skew. What is an ECL D flip-flop? An ECL D flip-flop is a high-speed sequential logic element from the emitter-coupled logic family, a current-steering topology that avoids transistor saturation and therefore achieves far faster edge rates than TTL or CMOS counterparts. Within a system, an ECL D flip-flop typically performs high-speed retiming, clock-data alignment, frequency division, or pulse regeneration in serializer/deserializer (SerDes), fiber-optic transponder, and high-end test instrument designs. ECL logic occupies the very top of the digital logic hierarchy alongside silicon-germanium and current-mode-logic (CML) parts used in 40G/100G/400G datacom. Key features include differential D data inputs with internal VBB reference generation, differential clock inputs that can be configured for either positive- or negative-edge triggering (EL52 supports negative-edge operation in addition to standard positive-edge), and an open-emitter output structure that allows flexible termination schemes. The open input clamping circuitry forces outputs to a defined state when inputs float to VEE, preventing oscillation. Operating supply voltages are VCC = 0V (ground) and VEE = -5.2V (or -4.5V), matching the legacy 10KH/100K ECL convention. Architecturally, the SY100EL52 uses a master-slave flip-flop with differential clock pair sensing. Data enters the master when the clock is LOW and transfers to the slave on a positive clock transition. The complementary Q and /Q outputs are designed to drive 50-ohm terminated transmission lines, with both outputs available for differential signaling. Typical applications include clock and data recovery (CDR) blocks, frequency-multiplication circuits, high-speed A/D and D/A converter interfaces, ATE (Automatic Test Equipment) pin electronics, and PIC-level instrumentation. Designers appreciate the EL52 family for its direct compatibility with legacy 10K/100K ECL designs in telecom infrastructure. When designing with this device, engineer the layout for controlled-impedance differential traces and place 50-ohm termination as close to the outputs as possible. Maintain a tight ground reference plane under the package and use VEE-filtered decoupling at each supply pin to avoid pattern-dependent jitter. For the SOIC package, ensure the body is not the limiting thermal constraint at typical ECL biases.

SY55853UKG

SY55853UKG - 2.5GHz Differential D-Type Latch | Microchip

The Microchip Technology SY55853UKG (originally Micrel Semiconductor) is a single-bit 2.5 GHz differential D-type transparent latch with fully differential source-terminated CML outputs, housed in a 10-pin MSOP (10-TFSOP, 3.00 mm width) package. A D-type transparent latch is a sequential logic element that, while enabled, flows input data directly to the output (transparent mode), and when disabled, stores or holds the last sampled bit. Within the signal-chain hierarchy, high-speed latches like the SY55853U family sit between pure combinational logic and flip-flops, providing pipelining, data synchronization, and asynchronous sampling in gigahertz-class signal paths such as clock distribution and data retiming circuits. Key features include a minimum toggle frequency (fmax) of 2.5 GHz, operation with a power supply up to 5.7 V, and a propagation delay of 400 ps. The device accepts CML, PECL, and LVPECL input logic levels, making it easy to drop into existing high-speed ECL-class signal chains without level-shifting circuitry. Architecturally, the SY55853UKG is fully differential from input to output. Source-terminated CML outputs deliver fast edge rates with controlled impedance, minimizing reflections and ringing on transmission-line PCB traces. The part is optimized to work within Micrel's SuperLite family of precision timing and interface products, sharing compatible logic levels and supply requirements across the family. Typical applications include high-speed data retiming in telecom and optical networking line cards, clock glitch-free switching and synchronization in test instrumentation, and sampling of fast serial data streams in ATE (automated test equipment) systems. Its GHz-class fmax and sub-ns propagation delay suit any path where setup/hold margins are measured in picoseconds. Design consideration: because the latch is obsolete (no longer manufactured), new designs should select an active Microchip Precision Edge or equivalent part, and existing designs should secure remaining distributor stock or qualify a drop-in substitute before final layout freeze. This page adds value beyond the datasheet by synthesizing distributor stock data, lifecycle status, drop-in family alternatives (SY55853UKC, SY55853UKI), and practical design notes for engineers managing last-time-buy decisions on obsolete high-speed logic.

SY58051AUMG - 10.7Gbps CML AnyGate, 16-QFN | Microchip

The Microchip Technology SY58051AUMG (originally Micrel Semiconductor) is an ultra-precision CML AnyGate universal differential logic gate with internal input and output termination, delivering a guaranteed maximum throughput of 10.7Gbps for data or 8GHz for clock signals, housed in a 16-pin QFN (3x3 mm) package with exposed pad. A CML (Current-Mode Logic) AnyGate is a configurable differential logic device that can implement many Boolean functions of two variables through pin strapping or configuration, rather than requiring a fixed gate type such as AND, OR, XOR, or multiplexer. Within the signal-chain hierarchy, it belongs to the family of high-speed logic ICs, sitting between pure clock buffers and full FPGA-based glue logic, and serves as a universal building block in high-speed digital, clocking, and data-conversion subsystems. Key differentiating features include the 10.7Gbps / 8GHz guaranteed throughput, ultra-low deterministic and random jitter performance suitable for SONET and Gigabit Ethernet clock trees, and a unique internal input termination network accessible via a dedicated VT pin. This VT-pin architecture allows the differential inputs to interface to different logic standards, both AC-coupled and DC-coupled, without external resistor-bias or termination networks, producing a clean, stub-free, low-jitter interface solution. Technically, the SY58051AU implements a 1:1 differential clock/data multiplexer function with CML output levels and integrated 50-ohm-style terminations, which reduces component count, minimizes stub reflections on the input traces, and improves signal integrity at multi-gigabit rates. The exposed-pad QFN-16 package provides a low-inductance ground path essential for jitter performance at these speeds. Typical applications include clock distribution and fanout trees for high-speed ADCs and FPGAs, SONET/SDH and 10G Ethernet line-card timing, retiming and multiplexing of redundant clock sources, and serial data path glue logic in optical modules and test instrumentation. Design consideration: the VT pin flexibility means the input termination should be configured deliberately for the source logic standard; AC-coupled sources require proper VT biasing to keep the input common-mode within the datasheet range. Keep the differential traces impedance-controlled at 50 ohms single-ended.

The Microchip Technology SY58051AUMG-TR is an ultra-fast, low-jitter universal CML logic gate (AnyGate) with a guaranteed maximum data throughput of 10.7 Gbps or clock throughput of 8 GHz, housed in a 16-pin QFN (3x3 mm) package with exposed pad. It operates from a 2.3 V to 3.465 V supply (2.5 V and 3.3 V nominal) across -40C to +85C. A universal logic gate is a differential high-speed gate that can be configured to realize many Boolean functions of two variables, such as AND, OR, NAND, NOR, XOR, and XNOR, by strapping or biasing its inputs. Within the signal-chain hierarchy it sits in the logic IC family alongside gates and inverters, but unlike standard CMOS logic it is built on a precision CML (current-mode logic) architecture optimized for multi-gigabit serial links rather than for static power savings. Key features include differential CML inputs and outputs with internal input and output termination, eliminating external resistor-bias and termination networks; a VT pin that exposes the input termination network for easy AC- or DC-coupled interfacing to multiple logic standards (LVPECL, LVDS, CML); and picosecond-class jitter performance suitable for SONET, Fibre Channel, and 10 Gigabit Ethernet timing budgets. The internal termination design produces a clean, stub-free interface, reducing reflections and jitter contributions at the package boundary. Because termination is integrated, board designers save the discrete resistor networks typically required at 10 Gbps, improving signal integrity and layout density. The exposed-pad QFN-16 provides a low-inductance ground return essential for CML switching at multi-gigahertz edge rates. Typical applications include 10G Ethernet and Fibre Channel retiming paths, clock distribution and gating in high-speed test equipment, logic gating in optical module signal chains, and protocol translation between CML, LVDS, and LVPECL domains. A key design consideration: the VT pin must be biased correctly for the chosen logic standard and coupling mode; AC-coupled CML and DC-coupled LVDS each require different VT configurations per the manufacturer datasheet.

SY88803VKG - 155Mbps PECL Limiting Post Amplifier | Microchip

The Microchip Technology (formerly Micrel) SY88803VKG is a 3.3V/5V, 155Mbps PECL low-power limiting post amplifier with a TTL Loss-of-Signal (LOS) output, housed in a 10-pin MSOP package. It is designed specifically for fiber-optic receiver front ends that follow a transimpedance amplifier (TIA). A limiting post amplifier is the second stage in an optical receiver signal chain. The linear signal output from a TIA can contain significant amounts of noise and may vary widely in amplitude; a limiting amplifier converts this small, noisy differential signal into a clean, fixed-amplitude logic-level PECL data stream, restoring signal integrity before clock-and-data-recovery (CDR) circuitry. In the hierarchy of optical receiver electronics, it sits between the TIA and the CDR/serializer, and is a form of special-purpose high-speed amplifier IC. Key features include single 3.3V or 5V supply operation to 155Mbps, low-noise PECL differential data outputs, a chatter-free TTL Loss-of-Signal output, a TTL /EN enable input for power management, and a programmable LOS assertion threshold. Low power consumption suits compact optical modules such as OC-3/STM-1 and Fast Ethernet transceivers. Architecturally, the device uses a cascade of wideband differential gain stages with automatic offset compensation; the saturating output stages guarantee constant output swing regardless of input amplitude above sensitivity. The programmable LOS threshold lets designers match the trip point to the optical module sensitivity budget, and the chatter-free hysteresis design prevents false LOS toggling near threshold. Typical applications include 155Mbps fiber-optic receivers, SDH/SONET OC-3 line cards, Fast Ethernet (100Base-FX) optical modules, and industrial fiber links. It connects directly to typical TIAs, making it a drop-in signal-chain element. Design consideration: route the differential PECL outputs as 50-ohm controlled-impedance pairs and decouple the supply pins close to the package to keep jitter low; verify the LOS threshold setting against the TIA output amplitude range.

Si2166-D60-GMR

Si2166-D60-GMR - DVB-S2X/S2/S Satellite TV Demodulator | Skyworks

The Skyworks Si2166-D60-GMR is a digital satellite TV demodulator IC supporting DVB-S, DVB-S2, and DVB-S2X standards in a single CMOS die, housed in a 48-pin QFN (7x7 mm) package. The part integrates a high-performance blind-scan algorithm for all three DVB-S standards and provides a programmable transport stream output interface compatible with all MPEG decoders and conditional access modules. The "D60" suffix denotes the firmware/die revision supporting DVB-S2X alongside legacy DVB-S/S2 reception. A digital TV demodulator is a baseband processor that recovers MPEG transport streams from a tuner-supplied IF signal. In a typical set-top box (STB) or iDTV front-end, a silicon tuner down-converts the RF satellite signal to a low-IF or zero-IF baseband signal, which the demodulator then decodes, error-corrects (LDPC/BCH for DVB-S2X), and outputs as a serial or parallel MPEG transport stream. The Si2166 family sits at the interface between the analog RF front-end and the digital MPEG decoder, and its standards compliance determines whether the end-product can receive next-generation ultra-HD satellite broadcasts. Key features include integrated blind scan for DVB-S/S2/S2X, on-chip blind-lock functionality, an adaptive equalizer for multi-path and weak-signal conditions, DiSEqC 2.x interface support for LNB control, and a flexible GPIO/I2C host control interface. The device operates from typical 1.2V/3.3V supplies and consumes modest power suitable for multi-tuner STB mainboards. Internal ADC and matched-filter blocks eliminate the need for external analog baseband components. Typical applications include DVB-S2X satellite set-top boxes (zapper, PVR, hybrid), integrated digital televisions (iDTVs), Free-to-Air (FTA) receivers, professional IRD (Integrated Receiver Decoder) equipment, and headend monitoring receivers. Designers pair the Si2166-D60-GMR with a companion wideband satellite tuner such as the Si2183 or Si2141 to form a complete RF-to-TS receive chain. When designing with this part, ensure the host processor supplies a stable 3.3V/1.2V rail with adequate decoupling near the supply pins, and route the IF input as a controlled-impedance 50 ohm microstrip. The host I2C bus runs at up to 400 kHz; verify pull-up sizing for the bus capacitance with the demodulator attached.

Si5330B-B00205-GM

Si5330B-B00205-GM - 1:4 LVDS Clock Buffer 710 MHz 24-QFN

The Skyworks Solutions Si5330B-B00205-GM is a 1:4 LVDS low-jitter, low-skew clock fanout buffer and level translator operating up to 710 MHz, housed in a 24-pin QFN with exposed pad. It accepts one single-ended or differential input and produces four differential (or eight single-ended) low-jitter LVDS outputs, making it well suited for high-performance PCB clock distribution. A clock buffer is a fanout device that takes one reference clock and produces multiple, phase-aligned copies for routing across a printed circuit board. Within the broader clock-tree hierarchy, the Si5330B sits between an upstream PLL/oscillator (frequency generation) and downstream transceivers, ASICs, FPGAs, or ADCs (clock consumption). Unlike a PLL-based clock generator, a buffer preserves the input frequency exactly and only regenerates the edges, minimizing added jitter and avoiding frequency translation artifacts. Key features include 710 MHz maximum input/output frequency, LVDS output format, 1:4 fanout, integrated input level translation (1.8 V, 2.5 V, or 3.3 V core with separate output-bank supply), and minimal crosstalk with strong supply-noise rejection. The exposed-pad QFN-24 package provides a low thermal resistance path for noise-sensitive systems. The device uses a differential LVDS output stage with internal source-terminated architecture, yielding sub-picosecond additive jitter at typical reference frequencies. Independent VDD pins for the input core and the output bank allow level translation without external circuitry, simplifying mixed-voltage designs. Typical applications include high-speed ADC/DAC sampling clocks, FPGA logic clock distribution, telecom/datacom line-card reference clocks, and PCI Express or serializer/deserializer reference fanout. Its low jitter makes it ideal for any noise-sensitive clock domain that needs a clean, multi-drop copy of a single reference. When designing with the Si5330B, follow the datasheet recommended termination for both LVDS inputs and outputs (typically 100 ohm differential) and decouple each VDD pin with a 0.1 uF ceramic placed as close to the IC as possible. The exposed pad must be soldered to a continuous ground plane for both thermal dissipation and controlled impedance. The custom B00205 ordering code defines the factory-set input/output configuration, so verify the variant matches your board's required direction.

Si5330B-B00205-GMR - 1:4 LVDS Clock Buffer 710MHz | Skyworks

The Skyworks Solutions (formerly Silicon Labs) Si5330B-B00205-GMR is a 1:4 LVDS low-jitter, low-skew fanout clock buffer and level translator housed in a 24-pin QFN-EP (4x4 mm) package. It accepts a single input clock and produces four differential LVDS outputs (or eight single-ended outputs) at frequencies from 5 MHz to 710 MHz, with guaranteed low additive jitter, low skew, and low propagation delay variability. A clock fanout buffer (also called a clock driver or clock distributor) is a semiconductor device that receives one input clock reference and replicates it onto multiple low-skew output clocks. Clock buffers sit in the timing-distribution hierarchy between an upstream PLL/oscillator and downstream loads such as FPGAs, ASICs, ADCs, DACs, and SerDes transceivers. By regenerating edges locally, they isolate the source from load-induced jitter and provide the deterministic phase alignment that high-speed digital links require. Differentiating features of the Si5330B family include a glitchless switching mux for redundant clocking applications, minimal cross-talk between outputs, and superior supply noise rejection that simplifies low-jitter distribution in noisy PCB environments. The device uses advanced CMOS technology, supports independent core and output-bank supply pins for integrated level translation without external circuitry, and accepts CML, HCSL, LVDS, or LVPECL inputs while driving LVDS outputs. The integrated input terminations remove the need for external resistor networks. From an architectural perspective, the Si5330B employs a precision differential input receiver followed by a low-jitter PLL-free fanout tree. Because the device does not synthesize new frequencies (it simply distributes and level-translates), its additive jitter contribution is small enough to preserve overall system margins even at 710 MHz operation. The output drivers are LVDS-compatible, providing the 350 mV swing required by ANSI/TIA/EIA-644 receivers. Typical additive jitter is in the sub-picosecond RMS range. Typical applications include clock distribution in communications infrastructure, redundant clocking for high-availability servers and storage, level translation between PECL/LVDS domains, and PCB-level fanout for FPGA, ASIC, and processor clock inputs. The wide 5-710 MHz operating range covers virtually all common telecom, networking, and computing reference frequencies. When designing with the Si5330B, designers should size the output-bank and core supply decoupling per Skyworks' reference layout and observe the LVDS receiver termination requirements (typically 100 ohm differential). The exposed pad must be soldered to a low-impedance ground plane for thermal and electrical performance.
