CS4207-CNZR - 4-In/6-Out HD Audio Codec w/ HP Amp | Cirrus Logic
The Cirrus Logic CS4207-CNZR is a highly integrated, multi-channel, low-power HD Audio Codec combining 192 kHz DACs, 96 kHz ADCs, 192 kHz S/PDIF transmitter and receiver, microphone preamp with bias voltage, and a ground-centered headphone driver, all in a 48-pin QFN (6x6 mm) package. The device operates from a single 3.3 V digital supply and a 5 V analog supply, delivers 24-bit serial audio data, and supports both HDA (HD Audio) and I2S serial interfaces to host controllers. An HD Audio Codec (High Definition Audio Codec) is a mixed-signal IC that converts digital audio streams from a PC/system chipset into line out the headphone, line stage, and microphone signals using internal DACs, ADCs, and headphone amplifiers. The codec sits in the audio signal chain between the host controller (e.g., Intel HDA-compliant chipset) and the analog transducers, and the term "HD Audio" denotes compliance with the Intel HDA Link specification rather than a frequency or bit-rate definition. CS4207-CNZR occupies the power-management IC and interface-IC tier of the audio subsystem, replacing multiple discrete ADCs, DACs, S/PDIF transceivers, and headphone amps with one package. The codec is the culmination of the signal chain (digital I/O -> mixed-signal codec -> analog out). Key features of the CS4207-CNZR include a multibit Delta-Sigma modulator architecture that enables infinite sample-rate adjustment from 32 kHz to 192 kHz, integrated ground-centered headphone driver (no DC blocking capacitors required at the output), microphone preamp with bias voltage source, and digital microphone interface support. The device supports 4 analog line/microphone inputs and 6 analog outputs, providing flexible routing for desktop, notebook, and embedded audio platforms. S/PDIF transmitter and receiver operate up to 192 kHz, allowing simultaneous digital audio transmission and reception. Technical depth: the Delta-Sigma modulator multibit topology achieves higher dynamic range and linearity than single-bit designs, while the ground-centered headphone architecture eliminates large output coupling capacitors, reducing BOM cost and improving low-frequency bass response. The codec integrates digital mixing, gain control, and jack-presence detection through the HDA link, simplifying host-driver interaction. Typical applications include desktop and notebook PC audio subsystems, all-in-one motherboards, embedded media players, and HD Audio-compatible docking stations. The wide format compatibility (HDA + I2S) and integrated HP amp make CS4207 well-suited for ultra-thin notebooks and small-form-factor designs where PCB area is constrained. When designing with this device, place the analog supply decoupling capacitors as close to the AVDD pins as possible to minimize analog-domain interference, and follow Cirrus Logic reference layout for the headphone output return paths to maintain low THD+N. The integrated HP amp eliminates external coupling capacitors but requires careful ground-centered routing to preserve low noise. This page synthesizes distributor pricing, parametric drop-in alternatives, and practical design notes that go beyond the manufacturer datasheet. Engineers comparing HD Audio codec options for desktop/notebook designs will find the application notes, thermal considerations, and HDA source documents consolidated in this page.
CS61584-IQ5 - Dual T1/E1 3.3V/5V Line Interface Unit | Cirrus Logic
The Cirrus Logic CS61584-IQ5 is a Dual T1/E1 Line Interface Unit (LIU) designed for short-haul and long-haul telecom applications, integrating two independent transceivers for T1 (1.544 Mbps) and E1 (2.048 Mbps) line formats in a single 64-pin TQFP (10x10 mm) package. The part operates from a single 5 V supply (4.75 V to 5.25 V), supports 3.3 V digital I/O via dedicated VDD_IO, and dissipates power dissipation of 310 mW typical. According to Cirrus Logic product listings, the device is housed in a TQFP-64 (10x10 mm) surface-mount package rated -40 C to +85 C industrial temperature range, and the IQ5 suffix indicates a specific speed/temperature grade per Cirrus Logic ordering nomenclature. A Line Interface Unit (LIU) is a physical-layer transceiver IC that sits between a framer/framer-LIU combination and the T1 or E1 twisted-pair line, performing transmit pulse shaping, receive equalization, clock/data recovery, and line monitoring. In the broader system hierarchy, an LIU belongs to the telecom interface IC family, which is itself a subset of interface ICs inside the integrated-circuits domain. T1 (used in North America/Japan) and E1 (used in Europe/most of the world) are the two dominant 1.544 Mbps / 2.048 Mbps PCM carrier standards originally defined for digital PSTN trunks; a dual-port LIU like the CS61584-IQ5 allows one chip to terminate two trunks, halving board area versus two discrete single-channel parts. Key features include integrated pulse-shaping and receive equalization for both T1 and E1, on-chip jitter attenuation, a serial host interface for per-channel configuration, hardware and software reset, and per-channel diagnostic loopbacks. The CS61584 supports both short-haul (CSU) and long-haul (DSX-1) line build-outs, selectable transmit pulse templates, and AMI/HDB3 line coding. Internal B8ZS/HDB3 encoders-decoders and unframed all-ones generator simplify BER testing and PRBS diagnostics without external framer intervention. Typical applications include channel banks, digital loop carriers (DLC), PBX trunk interfaces, T1/E1 multiplexers, ISDN primary-rate (PRI) adapter cards, and base-station backhaul. Because the CS61584 integrates dual transceivers and the typical power is held to 310 mW, the part is well-suited to compact multi-port cards where thermal budget is constrained. Designers should provide proper 1:2 or 1:1.15 line-side transformers and 75 ohm (E1) or 100 ohm (T1) termination networks per ITU-T G.703, maintain solid ground planes around the analog TX/RX pins to limit crosstalk between the two channels, and ensure VDD_IO matches the host framer logic level to avoid contention. For EMC/ESD robustness, TVS protection on the line-side tip/ring pairs is recommended. This page combines distributor pricing, same-family Cirrus Logic CS61584A variants, and parametric alternatives in the same 64-pin TQFP (10x10) footprint to give engineers a complete procurement and drop-in-replacement view not consolidated elsewhere.
CXD90070GG - PS5 Slim SSD Controller BGA IC | Sony Interactive Entertainment
The Sony Interactive Entertainment (SIE) CXD90070GG is a custom SSD controller and Southbridge IC used on the Sony PlayStation 5 Slim (PS5 Slim) motherboard revision EDM-033, presented in a BGA package. It functions as the secondary controller that bridges the PS5's custom SSD storage subsystem with the console's main APU, managing NVMe protocol traffic, SSD command queuing, and PS5-specific security handshakes on the Slim chassis. It is supplied exclusively through repair-parts channels rather than mainstream franchised distributors and is targeted at PS5 Slim console repair technicians. A Southbridge IC is a peripheral controller chip that sits between a high-performance application processor and lower-speed peripherals such as storage, USB, audio, and networking. In modern SoC-centric designs like the PS5, the legacy Northbridge/Southbridge architecture has been condensed into multiple custom companion controllers - the CXD90070GG is one such companion, focused on high-throughput SSD/NVMe bridging. It belongs to the broader taxonomy SSD controller > storage controller > peripheral IC > integrated circuit, and is closely related to the CXD90062GG and CXD90071GG controllers used in earlier PS5 motherboard revisions. Key features include BGA surface-mount construction compatible with PS5 Slim EDM-033 board layout, custom firmware tied to PS5 storage subsystem, and a reballed variant offered for repair workflows. The chip is supplied either as a bare die-on-substrate BGA or in reballed form with fresh solder balls for hot-air or IR rework on PS5 Slim motherboards. It is only relevant to console repair markets, not to general industrial or commercial SSD applications. The CXD90070GG communicates with the PS5 APU over a high-speed serialized interface and is responsible for SSD command routing, wear-leveling acceleration, and Thermal/POWER-state coordination. It implements custom SIE-proprietary signaling rather than a public standards-based NVMe controller interface, and is paired with CXD90064GG and CXD90071GG companion chips on the full PS5 Slim main board. Typical applications are PS5 Slim console repair, PS5 Slim storage fault diagnosis (BD-internal error codes related to SSD / E2E storage), SSD controller replacement on failed PS5 Slim motherboards, and custom controller firmware research. The wide operating envelope is constrained by the PS5 Slim chassis thermal and power design rather than industrial-grade specs. When sourcing this part, note that it is supplied almost exclusively through independent distributors and surplus channels rather than through franchised stockists such as DigiKey or Mouser. Each CXD90070GG for PS5 Slim EDM-033 should be verified against the motherboard revision before installation. Technicians commonly reball the BGA before mounting to avoid cold-joint failures. This page synthesizes distributor pricing ranges, repair-market context, and pin-compatibility notes for the CXD90070GG that are not consolidated on any single manufacturer datasheet, given that Sony Interactive Entertainment does not publish a public datasheet for this part.
CY7C65213-28PVXI - USB-UART LP Bridge Controller 28-SSOP | Infineon
The Infineon CY7C65213-28PVXI is a fully integrated USB-to-UART bridge controller that provides a single-chip solution for upgrading legacy UART peripherals to USB. Housed in a 28-pin SSOP package, it integrates a USB 2.0 Full-Speed controller, a UART transceiver, an internal 3.3V regulator, an internal oscillator, and 512 bytes of flash configuration memory. The part supports a UART data rate of up to 3 Mbps with 7 or 8 data bits and includes general-purpose I/O pins for status and control signalling. A USB-to-UART bridge is a class of bridge controller that translates between the USB protocol on the host side and an asynchronous serial (UART) interface on the device side, allowing legacy RS-232-style peripherals to gain modern USB connectivity without redesign. Within the broader product taxonomy, the CY7C65213 sits at the hierarchy: USB bridge controller -> interface IC -> communication IC -> semiconductor device. Its integrated regulator removes the need for an external 3.3V supply, and its internal oscillator removes the need for an external crystal, simplifying the BOM to a handful of decoupling capacitors. Key features include USB 2.0 Full-Speed (12 Mbps) compliance, support for USB suspend and resume signalling, hardware and software flow control ( RTS/CTS and XON/XOFF), integrated 512-byte flash for custom VID/PID and descriptor storage, configurable GPIO, and an industrial operating temperature range of -40C to +85C. The internal LDO supports bus-powered or self-powered configurations as defined by the USB 2.0 specification, simplifying the upstream power-section design. Architecturally, the CY7C65213 uses a serial interface engine (SIE) for USB protocol handling and a dedicated UART block with FIFO buffers, offloading all USB enumeration and protocol management from the host MCU. This lets designers replace legacy RS-232 transceivers with a single chip and a USB connector, reducing board area, BOM cost, and firmware complexity. Typical applications include USB-to-serial dongles for embedded debugging, industrial sensor readout with USB connectivity, point-of-sale (POS) terminals that expose legacy UART peripherals to PCs, and upgrade modules for legacy RS-232 equipment. The integrated flash also supports manufacturer-specific descriptors, allowing direct use as a branded device rather than requiring a generic-CDC driver. When designing with the CY7C65213, treat the VBUS and D+/D- lines as a controlled-impedance 90 ohm differential pair (per USB 2.0), and place the internal-regulator decoupling capacitors (typically 1uF and 0.1uF ceramic) within 1-2 mm of the VCCD pin. Note that the 28-SSOP variant is pin-to-pin compatible with the FTDI FT232R-style footprint when migrating designs across bridge vendors. This page synthesizes Infineon parameter data, distributor pricing tiers, and a curated drop-in alternative list that is not present on the manufacturer datasheet - giving engineers one consolidated source for sourcing, comparison, and PCB-level substitution decisions.
CY7C65213-32LTXIT - USB to UART Bridge 3Mbps | Infineon
The Infineon Technologies CY7C65213-32LTXIT (originally Cypress Semiconductor) is a fully integrated USB-to-UART bridge controller with USB 2.0 Full-Speed interface, up to 3 Mbps UART data rate, and 8 GPIOs, housed in a 32-pin QFN (5x5 mm) package with exposed pad. A USB-UART bridge IC is a type of interface controller that converts between a USB host port and a standard asynchronous serial (UART) port, allowing legacy serial devices to communicate over USB. Within the semiconductor hierarchy it belongs to the interface IC family, specifically USB bridge controllers, which sit between USB transceivers and application processors in a typical connectivity signal chain. Bridges handle enumeration, protocol conversion, and flow control so the host sees a standard COM port without custom drivers at the hardware level. Key features of the CY7C65213 include a USB 2.0 Full-Speed (12 Mbps) controller, a UART transceiver supporting data rates up to 3 Mbps, RS232/RS485 protocol support, 8 configurable GPIOs, an integrated 512-byte flash for vendor customization, an internal 3.3V regulator allowing 3.3V or 5V operation, and an internal oscillator that eliminates the need for an external crystal. This high level of integration minimizes the external bill of materials to essentially a USB connector and a few decoupling capacitors. Architecturally, the device combines the USB full-speed engine, serial interface engine, UART transceiver, and flash memory in a single low-power controller. The internal regulator and oscillator reduce design complexity and cost compared with discrete two-chip USB-to-serial solutions, while the GPIOs enable control signals such as RTS/CTS hardware flow control or status LEDs. Typical applications include upgrading legacy UART-based devices to USB, industrial equipment with RS232/RS485 links, point-of-sale terminals, set-top boxes, and development/debug UART consoles for embedded processors. According to Infineon, the CY7C65213 is pin-to-pin compatible with the FTDI FT232R, making it a recognized drop-in replacement in 32-QFN implementations. A key design consideration: verify the UART voltage domain, since the device operates from 3.3V or 5V via its internal regulator, and confirm flow-control pin mapping when replacing an FT232R layout because some secondary features differ. This page synthesizes distributor pricing, drop-in alternative analysis, and practical design notes not found in the manufacturer datasheet.
CY7C65213A-32LTXI - USB-UART Bridge Controller, RS485, 32-QFN | Infineon
The Infineon CY7C65213A-32LTXI is a fully-integrated USB-to-UART bridge controller housed in a 32-pin QFN (5x5 mm) package with USB 2.0 Full-Speed compliance, RS485 transceiver support, up to 3 Mbps UART data rate, and 8 configurable GPIO pins. It is the A-revision (CY7C65213A) enhancement of the original CY7C65213, adding RS485 signaling while retaining pin-compatibility with the 32-QFN footprint used by the legacy part. An internal 3.3V LDO, internal oscillator, and 512-byte on-chip configuration memory are integrated, allowing a minimal-BOM upgrade path for legacy UART peripherals to USB. A USB-to-UART bridge controller is a class of interface IC that bridges the USB protocol stack on the host side with an asynchronous serial (UART) interface on the device side. The bridge category sits within the broader hierarchy of interface ICs -> protocol converters -> bus bridges -> integrated circuits. EZ-USB bridge controllers are used when an existing embedded design with a UART (RS232, RS422, or RS485 logic levels) must be exposed to a modern PC or embedded processor that has dropped legacy serial I/O. Compared to discrete USB-to-UART implementations (USB transceiver + microcontroller + firmware), an integrated bridge reduces BOM count, PCB area, and time-to-market. Key features of the CY7C65213A include a USB 2.0 Full-Speed (12 Mbps) peripheral controller with integrated transceiver, a UART supporting RS232/RS422/RS485 multi-protocol modes, eight GPIOs that can be assigned as UART handshaking or general-purpose I/O, a 512-byte on-chip configuration flash for vendor-specific descriptors, and a wide operating temperature range of -40C to +85C for industrial environments. The integrated clock and regulator remove the need for an external crystal and 3.3V supply rail. From an architecture standpoint, the CY7C65213A uses a fixed-function USB 2.0 full-speed serial interface engine (SIE), a hardware UART engine, and on-chip RAM/ROM for the USB stack. Because firmware is fixed in ROM, designers cannot modify the USB stack behavior, but the 512-byte flash region enables custom USB VID/PID, manufacturer string, and GPIO behavior configuration at production time via Infineon's USB-Serial Configuration Utility. Typical applications for the CY7C65213A-32LTXI include industrial RS485 field-bus nodes, point-of-sale (POS) terminals, USB-to-RS232 adapter cables, factory automation equipment, and any legacy UART device migrating to USB. The QFN-32 (5x5 mm) footprint supports compact handheld designs. When designing with this device, observe the USB-IF signaling layout guidelines: place the 24 MHz crystal reference (or use the internal oscillator), keep the D+/D- differential pair length-matched within 4 mm, and provide a USB-compliant 90.9 ohm differential impedance on the upstream USB traces. Bulk decoupling should include a 4.7 uF capacitor on VBUS and a 0.1 uF capacitor on each supply pin.

CY7C65621-56LTXC - USB 2.0 2-Port Hub Controller | Infineon
The Infineon CY7C65621-56LTXC is a low-power USB 2.0 hub controller from the EZ-USB HX2LP Lite family, providing two downstream ports with single-TT bus-powered support in a 56-QFN (8x8 mm) package. It integrates USB 2.0 compliance, an upstream port, and two downstream ports on a single chip, replacing discrete hub designs with a compact surface-mount solution. A USB 2.0 hub controller is a class of interface IC that expands one upstream USB port into multiple downstream ports, handling transaction translation (TT), signal conditioning, and protocol compliance. The HX2LP Lite family belongs to Infineon's USB hub controller hierarchy, sitting between USB transceivers (physical layer only) and full USB host controllers (which add host-role processing). This positions the CY7C65621 as a self-contained USB 2.0 hub IC suitable for embedded systems without an internal root hub. Key features include USB 2.0 compliance at low-, full-, and high-speed (480 Mbps), integrated upstream and downstream transceivers, single-TTT transaction translation, bus-powered or self-powered operation, and per-port overcurrent detection. The 56-QFN package provides a low-profile footprint for space-constrained designs such as docking stations, monitors, and embedded motherboards. The CY7C65621 employs a serial interface engine plus a hub repeater architecture, offloading USB protocol overhead from the system processor. Per-port overcurrent sensing and ganged-power-switching reduce BOM cost, while internal pull-up/pull-down resistors simplify PCB layout by removing most external USB components. Typical applications include USB 2.0 hubs and docking stations, monitors with integrated USB ports, embedded motherboards, industrial USB expansion modules, and consumer peripherals such as printers. The wide operating voltage and low suspend current also make it suitable for battery-powered USB expansion accessories. When designing with this device, follow Infineon's reference schematic for USB impedance-controlled routing (90 ohm differential) and place the 24 MHz crystal within 5 mm of the XTALIN/XTALOUT pins. Decouple VBATT and VDD with 1uF ceramic capacitors placed within 2 mm of the respective pins. This page synthesizes distributor pricing, drop-in alternative listings, and PCB layout design notes not found in the manufacturer datasheet alone.
CY7C65621-56LTXCT - 4-Port USB 2.0 Hub Controller | Infineon
The Infineon CY7C65621-56LTXCT is a 4-port, USB 2.0 hub controller from the EZ-USB HX2LP Lite low-power family, supplied in a 56-pin QFN (8x8 mm) package with 0.90 mm height. It implements a USB 2.0 high-speed hub with integrated upstream and downstream termination resistors, integrated port status indicator control, and a 24 MHz external crystal with internal PLL. The device operates from a single 3.3 V supply and supports bus-powered and self-powered topologies. A USB hub controller is a protocol-aware bridge that expands one upstream USB port into multiple downstream ports while handling the USB 2.0 hub specification, including transaction translator (TT) logic, port power switching coordination, and over-current protection signaling. The HX2LP Lite family sits in the broader product hierarchy of USB interface IC -> interface IC -> integrated circuit, and is engineered specifically for low-power embedded hubs where standby current, BOM cost, and PCB area are critical. Key features include support for USB 2.0 high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) signaling, in-system EEPROM programming via SPI for vendor ID, product ID, and port customization, integrated upstream and downstream termination resistors that eliminate external components, and integrated LED status indicator drivers per port. The CY7C65621 variant provides four downstream ports, while the related CY7C65631 variant targets two-port designs. From an architectural perspective, the HX2LP Lite integrates the physical layer (PHY), serial interface engine (SIE), hub repeater, transaction translator, and power-management state machine into a single die. This integration reduces external component count compared to discrete hub designs, where multiple transceivers and a separate hub controller IC are required. According to the Cypress/Infineon datasheet, the integrated PLL derives all required USB clocks from a single 24 MHz crystal, eliminating the need for an external clock generator. Typical applications include USB port expansion on laptops, docking stations, monitors with built-in USB hubs, embedded industrial PCs, and consumer electronics such as set-top boxes and game consoles. The commercial temperature grade (0C to +70C) suits indoor commercial environments. When designing with this device, allocate 10 uF plus 0.1 uF ceramic bypass capacitors close to the 3.3 V supply pin, route the USB 2.0 differential pairs (D+/D-) with 90 ohm differential impedance, and ensure the upstream port's VBUS sensing resistor is selected per the USB 2.0 bus-power budget. The 56-QFN package requires thermal relief on the exposed pad connected to the ground plane. This page synthesizes distributor pricing, same-package alternatives, application context, and design considerations that are not consolidated in the manufacturer datasheet. Source data was retrieved from Mouser, DigiKey, Octopart, and the Infineon product page as of 2026-10-07.
CY7C65632-28LTXCT - USB 2.0 4-Port Hub Controller | Infineon
The Infineon CY7C65632-28LTXCT is a low-power USB 2.0 hub controller from the EZ-USB HX2VL family, supplying up to four downstream ports in a 28-pin QFN package. It is USB 2.0 specification compliant, operates from a single 3.3 V supply, and integrates a single Transaction Translator (TT) for full-/low-speed downstream support, targeted at cost-sensitive hub designs. A USB 2.0 hub controller is a function-specific integrated circuit that aggregates one upstream USB port into multiple downstream USB ports while managing enumeration, power switching, bus enumeration, and transaction translation between the host and connected devices. It belongs to the broader category of USB Interface ICs, within the larger Interface ICs and Integrated Circuits taxonomy. By placing the hub logic and downstream port control on a single die, the HX2VL part eliminates the external TT IC typically required by multi-TT hubs and cuts the BOM for 2- and 4-port hubs. Key features include integrated upstream and downstream USB termination resistors, integrated port-status indicator control (LED drivers), an integrated 24 MHz crystal amplifier, an in-system EEPROM interface for vendor ID / product ID / port-remap customization, and per-port overcurrent detection. The device is configurable via GPIOs to expose 2-port or 4-port topologies and supports both self-powered and bus-powered hub operation. Suspend current consumption is held to a minimum to meet USB 2.0 suspend-current requirements for bus-powered applications. Internally, the HX2VL uses a serial-interface engine for the upstream port and a hub repeater/transaction-translator architecture for the downstream ports, with port-mapping logic driven by the optional external EEPROM. The integrated termination and indicator control reduce PCB area to roughly a 4-layer design with no external PHY, which is the dominant reason designers select this part for compact hub dongles and embedded USB ports. Typical applications include standalone 4-port USB 2.0 hubs for consumer desktops, laptop port replicators, monitors with embedded USB hubs, embedded motherboards, and printer front-panel USB ports. The part is also deployed in industrial USB expansion modules where the GPIO-driven port remapping supports non-standard pin assignments. Designers should keep the 24 MHz crystal or clock source within 5 mm of the XIN/XOUT pins, route the DP/DM differential pairs with 90-ohm differential impedance, and place the upstream port termination near the device pins to preserve USB 2.0 high-speed signal integrity. The optional EEPROM is only required if custom VID/PID or port-disable remapping is needed. This page synthesizes distributor pricing, drop-in same-package alternatives, and practical design notes drawn from the manufacturer datasheet and field experience, in a form that distributors' product pages do not offer.
CY7C65632-48AXCT - HX2VL USB 2.0 4-Port Hub Controller | Infineon
The Infineon CY7C65632-48AXCT is a Very Low-Power USB 2.0 Hub Controller from the HX2VL family, supporting up to four downstream ports with integrated upstream and downstream transceivers, a USB Serial Interface Engine (SIE), USB Hub Control and Repeater logic, and Transaction Translator (TT) logic. It operates from a 3.15 V to 5.25 V supply, ships in a 48-pin TQFP (7x7 mm) package, and is qualified for the 0 to 70 C commercial temperature range. The part is supplied on Tape and Reel (TR) in the 48-AXC shipping form. A USB 2.0 hub controller is a specialized bus controller that expands a single USB upstream port into multiple downstream ports while maintaining the USB 2.0 protocol envelope. It sits hierarchically as: USB hub controller -> USB interface IC -> interface controller -> mixed-signal IC -> integrated circuit -> semiconductor. The HX2VL family targets very-low-power applications, integrating external components such as the voltage regulator and pull-up/pull-down resistors to reduce BOM cost and PCB area. Key features include a 4-port single-TT topology, configurable GPIOs, an integrated LED indicator control for per-port status, in-system EEPROM programming support, and a 24 MHz external crystal reference with an integrated PLL. The 48-AXC package reduces board space versus the 56-pin QFN variant while exposing full downstream port count plus JTAG/EEPROM/reset pins. The integrated upstream termination, integrated 1.5 kohm upstream pull-up (configurable via the DM_DAT signal path), and embedded regulator simplify the schematic to a few external discretes. From an architectural perspective, the HX2VL combines a USB 2.0 high-speed physical layer with a Transaction Translator block for full-/low-speed split transactions. The chip supports a Single-TT (one shared TT per hub) architecture rather than Multi-TT (per-port TT) - this trades downstream full-speed concurrent bandwidth for lower silicon cost and lower power dissipation. Per Infineon datasheet, the embedded regulator provides a 3.3 V internal rail from a 5 V VBUS-tolerant supply, simplifying designs that lack an external 3.3 V LDO. Typical applications include USB 2.0 hubs and docking stations, monitors with embedded USB ports, notebook port replicators, retail POS terminals, and embedded platforms requiring USB expansion from a single host port. Compared with the CY7C65634 (DS-port multi-mode part), the CY7C65632 is the Single-TT configuration with shared per-port TT logic. When designing with this part, place the 24 MHz crystal within 5 mm of the XI/XO pins and add bulk decoupling (4.7 uF plus 0.1 uF) close to VCC. Configure the upstream pull-up through the DM_DAT pin per the Infineon HX2VL datasheet to ensure proper USB enumeration. For cost-sensitive designs, the 48-TQFP keeps PCB layout simpler than the 56-pin QFN variant (CY7C65632-56LTXC).
CY7C65642-28LTXCT - USB 2.0 TetraHub Controller, 28-QFN | Infineon
The Infineon CY7C65642-28LTXCT is a USB 2.0 TetraHub controller from the EZ-USB HX2VL family, providing four downstream ports with one dedicated Transaction Translator (TT) per port in a 28-pin QFN (5x5 mm) package. It supports USB Full-Speed (12 Mbps) and High-Speed (480 Mbps) operation and integrates I2C and SPI interfaces for hub-configuration access. The device operates from a single 3.3V or 5V supply and is qualified for the commercial 0C to +70C temperature range. A USB hub is a class of interface IC that expands a single upstream USB port into multiple downstream ports while managing traffic scheduling, transaction translation between High-Speed and Full-/Low-Speed devices, and per-port power control. TetraHub controllers such as the CY7C65642 occupy the niche between fixed-port hubs (typically 4-port with one shared TT) and high-end 7-port enterprise hubs - balancing low cost, low power, and Multi-TT throughput for monitor docks, embedded PCs, and consumer peripherals. Key features of the CY7C65642 include very low suspend current (typical USB bus-power compliant), per-port over-current protection inputs, integrated upstream and downstream USB transceivers, configurable GPIOs, and optional EEPROM support for vendor-specific VID/PID and string descriptors. The Multi-TT architecture lets each downstream port run its own TT, eliminating bandwidth contention when multiple Full-Speed devices are connected downstream. Internally, the silicon implements a UTMI-compliant physical layer, a serial interface engine, and dedicated TTs that buffer and translate split transactions. This means that a Full-Speed device plugged into port 2 and a Full-Speed printer on port 3 each see full 12 Mbps rather than sharing a single TT bottleneck. The CY7C65642 series is offered in 48-pin TQFP and 28-pin QFN variants; the 28-QFN option targets space-constrained PCB designs. Typical applications include USB 2.0 hub expansion boards, monitor docking stations, point-of-sale terminals, embedded industrial PCs, printer peripherals, and USB port multipliers on motherboards. The Multi-TT architecture is particularly valuable for docking stations that must aggregate several USB Full-Speed peripherals (keyboard, mouse, headset) without throughput loss. When designing with the CY7C65642, ensure the upstream USB D+/D- pair carries a 90-ohm differential impedance and that the crystal or clock source meets the USB 2.0 jitter specification. Unused downstream ports should follow Infineon application note KBA89012 for bias and termination. Power decoupling close to VCC pins is critical to meet USB suspend-current requirements. This page synthesizes distributor pricing across nine channels, drop-in and same-family alternatives, and practical design notes that complement - not duplicate - the manufacturer datasheet.
CYPD3135-40LQXI - EZ-PD CCG3 USB-C PD Controller | Infineon
The Infineon CYPD3135-40LQXI is an ARM Cortex-M0 based EZ-PD CCG3 USB Type-C port controller supporting USB Power Delivery 3.0, packaged in a 40-pin UFQFN with exposed pad.

CYUSB3328-88LTXC - HX3 USB 5 Gbps Hub Controller | Infineon
The Infineon CYUSB3328-88LTXC is an EZ-USB HX3 USB 3.0 hub controller built around an ARM Cortex-M0 core with 32 KB of on-chip ROM, supporting SuperSpeed USB (5 Gbps) and high-speed/legacy USB on a downstream port set. Housed in an 88-VFQFN-EP package (10x10 mm) with exposed thermal pad, the device integrates a USB Billboard controller, a USB-C Bridge controller, and an integrated Dock Management Controller (DMC) that enables firmware upgrades over the USB link, signed firmware download via DMC, and rich downstream port customization including per-port power control and charging hand-off. A USB 3.0 hub controller is a specialized Application-Specific Standard Product (ASSP) that bridges one upstream USB connection to multiple downstream USB connections while managing enumeration, power, and traffic scheduling. The CYUSB3328 specifically sits in the taxonomy: USB hub -> SuperSpeed hub -> USB 3.0 hub controller -> mixed-signal ASSP -> semiconductor. By consolidating PHY, hub logic, and bridge/billboard functions in a single chip, the HX3 family reduces board area, BOM cost, and design complexity for docking stations, monitors, embedded systems, and charging hubs. The 5 Gbps SuperSpeed datapath is critical because USB 3.0's effective throughput (~400 MB/s after protocol overhead) is required by external storage, SSD enclosures, and 4K video capture where USB 2.0 would bottleneck. Key features include 5 Gbps SuperSpeed USB 3.0 with backward-compatible USB 2.0/1.1 signaling, an integrated 8-port capable hub (this part exposes 1 upstream + configurable downstream ports), native USB Power Delivery 3.0, Battery Charging v1.2 (BC v1.2) and Apple Charging support, firmware upgradability over USB with signed firmware verification, integrated USB Billboard for Alternate Mode failure reporting, and a 32 KB on-chip ROM that holds the bootloader and runtime stack. The part operates from a single 3.3 V supply and provides GPIO for port indicators and VBUS control. The CYUSB3328 architecture pairs a Cortex-M0 management CPU with a SuperSpeed hub controller block. The M0 handles USB enumeration, descriptor requests, Billboard messaging, dock management, and host-facing I2C/GPIO, while the hub block implements USB-IF defined hub states and per-port transaction translators for full-/low-speed legacy devices. The integrated PHY for both SS and HS/FS/LS signaling eliminates external PHY components. The DMC firmware is loaded over USB or I2C and can be signed for production; this allows OEMs to customize port behavior, VID/PID, charging profiles, and alternate-mode fallback messaging without changing external silicon. Typical applications include USB Type-C docking stations, USB 3.0 hubs with charging, 4K monitor/USB-C display docks, point-of-sale terminals with multiple USB peripherals, and embedded systems that need to expose several USB ports from a single upstream port. The combination of SuperSpeed hub + billboard + PD-aware charging is targeted at docking stations where USB-C Alternate Mode must be gracefully reported when the connected host cannot enter DP/PCIe alternate mode. Design consideration: the 88-VFQFN-EP package requires a continuous ground/power plane beneath the exposed pad for thermal and signal-integrity reasons; missing the EP solder connection will cause severe thermal throttling and signal-integrity degradation at 5 Gbps. Always reference Infineon's HX3 hardware design guide for 90-ohm differential SuperSpeed routing. This page synthesizes Infineon-authoritative datasheet parameters, real distributor pricing as of 2026-10-07, structured drop-in alternatives, and HX3-family design guidance not consolidated elsewhere on the open web.
CYUSB3328-88LTXI - HX3 USB 3.0 8-Port Hub Controller | Infineon
The Infineon CYUSB3328-88LTXI is a USB 3.0 SuperSpeed hub controller from the EZ-USB HX3 family, integrating an ARM Cortex-M0 microcontroller core with 32 KB ROM, a 5 Gbps USB 3.0 PHY, and an 88-pin VFQFN exposed-pad package. The device delivers four downstream USB 3.0 ports plus a USB 3.1 Gen 2 upstream port, supporting up to 8 logical downstream ports via an integrated Dock Management Controller (DMC) and USB-C bridge functionality. Native battery-charging support includes USB Power Delivery 3.0, Battery Charging v1.2, and Apple Charging signatures. What is a USB hub controller? A USB hub controller is a system-on-chip that aggregates multiple downstream USB ports into a single upstream connection, expanding the connectivity of a host computer or embedded system. Within the broader taxonomy, it falls under Interface ICs -> USB Controllers -> USB Hub Controllers, occupying the link layer between the USB host controller (typically integrated into a PC chipset) and downstream peripheral devices. HX3 specifically targets SuperSpeed (5 Gbps) industrial, docking-station, and embedded applications where firmware upgradability and signed-firmware authentication are required. Key features of the CYUSB3328-88LTXI include: 5 Gbps USB 3.0 SuperSpeed on every port, native support for USB-C billboard and bridge modes, integrated 100-mA charging per port, firmware field-upgradeable over USB with cryptographic signing through the DMC, and a 3.0V to 3.6V single-supply operation. The 88-VFQFN exposed pad offers a thermal resistance suitable for fanless industrial enclosures, while industrial temperature grade (-40C to +85C) allows deployment in factory automation and outdoor signage. Technically, the HX3 architecture pairs an ARM Cortex-M0 control processor with four dedicated USB 3.0 physical layers and a shared USB 2.0 high-speed hub block. The DMC co-processor manages USB Power Delivery negotiation, USB-C orientation detection, and Billboard device emulation for Alternate Mode failures, removing the need for an external PD controller. Signed firmware downloads via DMC prevent unauthorized firmware injection - a critical security feature for IT-provisioned enterprise docks. Typical applications include USB-C docking stations for laptops, multi-monitor KVMs, industrial panel PCs with multiple USB peripherals, USB-C chargers with embedded hub functionality, and embedded test equipment that must aggregate four USB 3.0 cameras or storage devices. The CYUSB3328-88LTXI fits these scenarios because of its integrated DMC, which reduces BOM cost versus discrete PD + hub designs. Designers should allocate a 4-layer PCB stack-up with continuous ground beneath the exposed pad for thermal dissipation, follow USB-IF compliance routing rules (90-ohm differential impedance for SuperSpeed pairs), and reserve a USB-I2C/SPI EEPROM footprint for firmware storage. The DMC handles USB-C orientation internally, so external USB-C multiplexer ICs are typically not required. This page synthesizes distributor pricing, drop-in same-package alternatives, and design notes not found in the manufacturer datasheet alone - including cross-reference entries from Infineon part-number variants (LTXC, LTXIT) that share the 88-VFQFN footprint.
DG187AA - SPST Analog Switch, JFET, TO-100-10 | Vishay
The Vishay Siliconix DG187AA is a single-channel SPST (single-pole single-throw) analog switch built around an N-channel JFET switching element with an integrated level-shifting driver. Housed in a 10-pin TO-100 metal can package (round, through-hole, 10 leads), it provides approximately 30 Ohm on-resistance and is part of the DG181 through DG191 analog-gate family originally introduced by Intersil and now manufactured by Vishay Siliconix. According to the verified distributor listings, it is categorized as an SPST analog switch IC. An analog switch (also called a JFET analog gate or solid-state analog switch) is an electronic component that uses a semiconductor device (typically a JFET or MOSFET) to connect or disconnect an analog signal path under the control of a digital logic input. Analog switches sit within the broader taxonomy of signal switches -> multiplexers/switches -> interface ICs -> integrated circuits, and they are essential whenever an analog signal must be routed without injecting distortion, charge injection, or significant series resistance. The DG187AA's JFET architecture keeps the on-resistance relatively constant over a wide analog signal range, which is a key advantage over simple MOSFET-only designs in precision instrumentation. Key differentiating features of the DG187AA include: (1) a high-speed level-shifting driver that accepts low-level CMOS/TTL-compatible inputs (down to approximately 0.8V to 2V) and uses them to control the JFET switch state, (2) analog signal range operation that suits both unipolar and bipolar audio/precision signals, (3) low charge injection thanks to the JFET topology, and (4) a hermetic TO-100 metal can that supports military temperature grades (-55C to +125C). The metal-can packaging also provides excellent EMI shielding for sensitive analog signal routing in instrumentation front-ends. In terms of electrical architecture, the DG187AA integrates the JFET switch die and the level-shifting driver die within a single TO-100 can, allowing the part to be driven directly from logic-level inputs without external pull-ups or level translators. This single-package integration reduces board area and simplifies PCB layout compared with discrete JFET-plus-driver implementations. The switching speed, while not as fast as modern CMOS analog switches, is sufficient for audio, instrumentation multiplexing, sample-and-hold front-ends, and legacy industrial signal routing. Typical applications for the DG187AA include: (1) precision instrumentation multiplexers, (2) audio signal routing in professional and broadcast equipment, (3) sample-and-hold amplifier front-ends, (4) data-acquisition system signal gating, (5) legacy industrial process-control signal switching, and (6) military and aerospace signal routing where the TO-100 hermetic can is required. The MIL-spec /883 variant (DG187AA/883) confirms the part's qualification for harsh-environment designs. When designing with the DG187AA, note that the TO-100 package has 10 leads arranged in a circular metal can, with pin 1 typically marked by a tab or dot near the package base. Because the package is a through-hole metal can (not surface-mount), PCB layout requires plated through-holes on a 0.230 inch lead circle typical of TO-100 cans. Always consult the manufacturer datasheet for the exact pinout, especially when migrating from the /883 to the commercial-temperature variant.

DG403 - Dual High-Speed SPDT Analog Switch, 44V | Analog Devices
The Analog Devices DG403 is an improved, dual high-speed SPDT (single-pole double-throw) CMOS analog switch designed for precision, high-performance switching of analog signals, with a maximum signal voltage range of 44V permitting control of 30Vp-p signals, guaranteed on-resistance matching of 2 ohm max between switches, and guaranteed on-resistance flatness of 3 ohm max over the signal range, housed in a 16-pin SOIC package. An analog switch is a semiconductor device that passes or blocks analog signals under digital control, acting as the solid-state equivalent of a relay contact. Within the signal-chain hierarchy, the DG403 belongs to the analog switches and multiplexers family, positioned below analog multiplexers (which route many channels) and above simple pass elements, and it is a core building block of analog front-end and signal-routing subsystems in data acquisition systems. Key features include CMOS or TTL-level compatible logic activation, operation from single-ended supplies of +5V to +34V or split supplies from plus/minus 5V to plus/minus 17V, and a high-voltage silicon-gate process. Each of the two independent control inputs selects between two signal paths, providing the equivalent of two SPDT relay contacts with no moving parts. The improved redesign (originally by Maxim Integrated, now Analog Devices) added guaranteed low on-resistance matching between switches and flatness over the signal range, while the epitaxial layer prevents the latch-up associated with older CMOS technologies. The ON-resistance variation with analog signal level is quite low over a plus/minus 15V analog input range, ensuring low signal distortion. Typical applications include audio and video signal routing, precision data-acquisition channel selection, sample-and-hold circuits, and replacing electromechanical relays in industrial and instrumentation signal paths. Where two single-pole single-throw contacts are needed, the DG401 offers SPST functionality; the DG405 offers DPST. Designers should observe supply-rail headroom: analog signal swings must remain within the supply rails, and logic inputs must meet CMOS/TTL threshold levels for correct switching.

DG411DY-E3 - Quad SPST 35Ohm CMOS Analog Switch | Vishay
The Vishay Siliconix DG411DY-E3 is a precision monolithic quad SPST CMOS analog switch IC featuring four independent 1:1 single-pole single-throw switches with a maximum on-resistance of 35 ohm, housed in a 16-pin SOIC package (0.154 inch, 3.90 mm width). It is a lead-free, RoHS-compliant member of the DG411 family designed for high-speed, low-error switching of precision analog signals. An analog switch is a semiconductor device that routes or blocks analog signal paths under digital control, sitting within the broader taxonomy: analog switch IC -> signal switch -> interface/signal-conditioning IC -> semiconductor. Quad SPST switches like the DG411 are the workhorses of analog front-end design, replacing electromechanical relays and discrete JFET switching where board space, speed, and reliability matter. Key features include extremely low power consumption of approximately 0.35 uW, TTL- and CMOS-compatible digital inputs, and low on-resistance matching between the four switches. The CMOS transmission-gate architecture conducts equally well in either direction, supporting bipolar analog signal swings when dual supplies are used. The -E3 suffix denotes tin/lead-free plating with RoHS compliance for modern assembly processes. Technically, each switch is built as a CMOS transmission gate with an n-channel and p-channel MOSFET in parallel, driven by level-shifting gate control circuitry derived from the digital input. This topology keeps on-resistance relatively flat over the analog signal range and minimizes charge injection, which is critical for sample-and-hold, integrator-reset, and audio signal-routing accuracy. Typical applications include audio and video signal switching, precision test-and-measurement signal routing, sample-and-hold circuits, and data-acquisition channel multiplexing, where its 35 ohm channel resistance and low quiescent power keep inserted errors and thermal drift small. Designers should verify total supply voltage headroom: the DG411 family is specified for dual supplies in the region of plus/minus 15 V, and signal swings must remain within the supply rails to avoid latch-up or increased distortion.

DG413DJ-E3 - Quad SPST CMOS Analog Switch 35 Ohm | Vishay
The Vishay Siliconix DG413DJ-E3 is a precision monolithic quad SPST CMOS analog switch with 35 ohm maximum on-resistance, four independent 1:1 switching channels, and a wide 5 V to 44 V supply range, housed in a 16-pin PDIP (0.300 in, 7.62 mm) through-hole package. An analog switch is a semiconductor device that routes or blocks analog signal paths under digital control, sitting within the broader hierarchy of interface ICs and signal routing components. Quad SPST switches such as this part provide four independent single-pole single-throw contacts that can pass signals in either direction with high off-isolation, unlike relays or discrete FET solutions which are larger and slower. The DG413 family from Vishay, like the related Analog Devices and Renesas DG411/DG412/DG413 parts, combines a 2-Normally-Open / 2-Normally-Closed channel configuration with TTL and CMOS-compatible logic inputs. Key features include 35 ohm on-resistance, low charge injection of 5 pC, -85 dB crosstalk at 1 MHz, and low off-state capacitances of 9 pF (CS(off)) and 9 pF (CD(off)). The device operates from -40 C to +85 C ambient and supports dual supplies of +/-13.5 V to +/-16.5 V as well as single-supply operation across the 5 V to 44 V range. Architecturally, the part uses CMOS transmission-gate switching cells driven by level-shifting logic inputs, enabling low error switching of precision analog signals with fast switching times. The E3 suffix denotes Vishay's lead-free, RoHS-compliant finishing. Typical applications include precision signal routing in test and measurement instrumentation, industrial process-control signal multiplexing, audio signal switching, and data-acquisition front-end channel selection where high off-isolation and low charge injection preserve signal fidelity. A key design consideration is that logic inputs must swing to the appropriate supply rails; driving the switch with logic levels referenced outside the supply range causes incorrect switching or damage.

DG419DY-T1-E3 - Precision CMOS SPDT Analog Switch | Vishay
The Vishay Siliconix DG419DY-T1-E3 is a single-pole double-throw (SPDT) precision monolithic CMOS analog switch that combines low power consumption with high switching speed and excellent signal integrity. Housed in an 8-pin SOIC (NSOIC) package, the part provides a single 2:1 switch channel with a typical on-resistance of 35 ohms, supporting analog signal rails up to ±15 V or 30 V single supply. The DG419DY-T1-E3 is supplied on a 3000-piece tape-and-reel carrier and targets precision signal routing in industrial, instrumentation, and battery-powered systems. An analog switch (also called a CMOS switch or bilateral switch) is an active semiconductor device that uses MOSFET transistors to pass or block analog signals. It belongs to the broader hierarchy of interface ICs -> analog switches/multiplexers -> signal conditioning -> data acquisition. Unlike electromechanical relays, CMOS analog switches offer nanosecond switching, low power draw, no contact bounce, and zero off-state current leakage when fully turned off, making them ideal for solid-state signal multiplexing in modern mixed-signal designs. Key features of the DG419DY-T1-E3 include a typical on-resistance of 35 ohms, low charge injection, break-before-make switching action, and TTL/CMOS-compatible digital logic inputs. The device operates from a single 10 V to 30 V supply or from dual ±5 V to ±15 V supplies, with a logic threshold that allows direct interface to 3.3 V or 5 V microcontrollers. Its low power consumption (under 35 mW quiescent) and rugged ESD protection make it suitable for both portable and line-powered designs. The DG419DY-T1-E3 uses a precision CMOS architecture with on-resistance matching between channels and flat on-resistance across the analog signal range, minimizing total harmonic distortion when passing audio or precision DC signals. The break-before-make switching topology prevents momentary shorts between input sources during channel transitions, which protects upstream drivers and downstream ADCs from current spikes. Typical applications include precision test equipment, guidance and control systems, battery-powered instrumentation, data acquisition front-ends, audio signal routing, sample-and-hold circuits, and programmable gain amplifiers. The wide operating voltage range and high off-isolation make it equally suitable for industrial 4-20 mA signal routing and for low-voltage sensor multiplexing. When designing with the DG419DY-T1-E3, observe the absolute maximum supply voltage of 44 V to avoid permanent damage. Place 0.1 µF decoupling capacitors close to V+ and V- pins, and ensure the logic input does not exceed V+ or fall below ground. For high-impedance source signals, add a small series resistor at the output to limit capacitive kickback during switching transitions.
