SE051

SE051 - EdgeLock IoT Secure Element, CC EAL6+ | NXP

The NXP Semiconductors SE051 is a Plug & Trust IoT secure element with Java Card operating system, CC EAL 6+ (AVA_VAN.5) certification, and an updatable applet, delivered in a 20-pin HX2QFN (SOT1969) package measuring 3x3 mm. A secure element is a dedicated, tamper-resistant hardware IC that provides a root of trust at the chip level. Within the system hierarchy, it sits below the host microcontroller in the security architecture (secure element -> hardware root of trust -> edge-to-cloud security platform) and offloads all cryptographic key storage and operations from the general-purpose MCU, so keys never exist in MCU memory where they could be exposed by software attacks. Key features include turnkey Plug & Trust design-in with a complete support package (middleware, development kits, reference designs), applet updatability in the field via SEMS Lite, and support for developer-created custom applets. The SE051 extends the widely adopted EdgeLock SE050 family, inheriting its proven Common Criteria EAL 6+ certification up to the OS level with AVA_VAN.5 vulnerability assessment. Technically, the SE051 runs a Java Card operating system and ships with a pre-installed applet optimized for IoT security use cases such as secure key storage, mutual authentication, and secure provisioning. Communication with the host processor is performed over a single-wire or I2C interface, following the same integration model as SE050, so existing SE050 host firmware and the Plug & Trust Nano middleware package can be reused directly. Typical applications include IoT device identity and cloud onboarding, secure firmware updates, peripheral node authentication in industrial networks, and smart-meter or payment-adjacent designs requiring certified hardware security. When designing the SE051 into a PCB, note that it is pin-to-pin and package compatible with EdgeLock SE050A/B/C/F variants (per NXP application note AN13014), enabling a single footprint to support SE050, SE050E, or SE051 depending on the required security feature set.

Key features of the SE051C2HQ1 include anti-cracking hardware protection, secure key storage, and secure firmware upgrade capability. Unlike its predecessor EdgeLock SE050, the SE051 supports applet updates in the field through NXP SEMS Lite and lets developers deploy custom applets, extending product lifecycles without hardware redesign. The device is certified to Common Criteria EAL6+ with AVA_VAN.5 vulnerability analysis up to the operating system level, one of the strongest certifications available for IoT secure elements. As part of the widely trusted EdgeLock SE050 Plug & Trust family, it maintains software and hardware compatibility, easing migration for existing SE050 designs. Typical applications include IoT device identity and attestation, secure cloud onboarding for smart home and industrial sensors, payment and authentication terminals, and protection of connected infrastructure against counterfeiting and credential theft. Designers should allow for secure key injection during manufacturing and plan the I2C communication interface routing per the Plug & Trust protocol; use NXP's Plug & Trust middleware to shorten integration time.

It communicates with the host MCU over I2C using the T=1 over I2C protocol. A secure element is a tamper-resistant hardware module that stores cryptographic keys, executes cryptographic operations, and provides a root of trust for connected devices. Within the power-management hierarchy of an IoT node, it sits alongside the microcontroller and radio as part of the broader class of security ICs and authentication microcontrollers, safeguarding device identity, cloud credentials, and firmware integrity. Key differentiating features include its FIPS 140-3 Level 3 certification - the first industrial secure element to achieve this - which provides out-of-the-box FIPS compliance without additional customer certification effort. The device ships as a turnkey platform with an updatable applet optimized for IoT security use cases preinstalled, reducing development effort dramatically. Architecturally, the SE052F runs its cryptographic functionality in a certified environment and is supported by NXP's Plug & Trust middleware, enabling easy design-in for host applications. A comprehensive product support package, including a development kit and evaluation documentation, accelerates time to market. Typical applications include Industrial IoT device identity and cloud onboarding, secure firmware over-the-air updates, and key storage for industrial gateways and sensors. Designers should note the package difference versus the SE050 family: the SE052F uses HVQFN20 (SOT917-6, 4x4 mm) while SE050 uses HX2QFN20 (SOT1969-1, 3x3 mm), so footprints are not interchangeable.

SGM8955XN5G

SGM8955XN5G - Zero-Drift Op Amp, 1-Ch, SOT-23-5 | SG Micro

The SG Micro SGM8955XN5G is a single-channel, micro-power, CMOS zero-drift operational amplifier housed in a 5-pin SOT-23-5 (XN5) surface-mount package. It delivers a 22 µV (MAX) offset voltage with 80 nV/°C offset drift, 100 dB open-loop gain, and 130 pA input bias current, optimized for precision signal chains operating from low-voltage rails. An operational amplifier (op amp) is a high-gain differential DC amplifier that uses external feedback components to set gain, bandwidth, and transfer characteristics. Zero-drift op amps employ either chopper or auto-zero (chopper-stabilized) architectures to continuously correct offset voltage, eliminating the 1/f flicker noise and offset drift that plague conventional CMOS and bipolar input stages. The SGM8955 belongs to the precision amplifier category within the broader linear IC hierarchy: operational amplifier → amplifier IC → analog signal chain → semiconductor. Key features of the SGM8955XN5G include a 20 µA typical quiescent supply current, 180 V/ms slew rate, rail-to-rail input and rail-to-rail output (RRIO) swing, EMI filtering/RF suppression on the inputs, and an integrated auto-zero calibration loop. The SOT-23-5 (XN5) package operates across -40 °C to +125 °C and supports supply voltages suitable for 2.7 V-5.5 V single-supply systems. The combination of low offset, low drift, low power, and RRIO makes the part a strong fit for battery-powered instrumentation, transducer conditioning, and precision ADC front ends. The SGM8955/6 architecture uses a chopper-stabilized CMOS input stage to achieve sub-50 µV offset, eliminating the periodic recalibration required by conventional CMOS amplifiers in precision applications. The internal EMI/RF input filter rejects high-frequency interference, simplifying PCB layout for sensor applications in electrically noisy environments. The 20 µA quiescent current and low shutdown leakage allow the part to remain continuously powered in battery applications without significantly reducing runtime. Typical applications include high-precision ADC driver circuits, weigh scale and strain gauge signal conditioning, thermocouple and bridge sensor amplifiers, portable medical instrumentation, battery-powered industrial sensors, and zero-drift transducer interfaces. The RRIO capability allows the part to operate at unity gain in single-supply systems where input and output signals swing close to either supply rail. When designing with the SGM8955XN5G, place the input capacitor as close to the op-amp input pins as possible, ensure the feedback network uses 1% or better resistors to maintain gain accuracy, and add an anti-aliasing RC network at the output when driving a downstream ADC. Estimated: total supply current is the sum of the 20 µA quiescent plus the load-dependent output stage current.

SGTL5000XNAA3R2

SGTL5000XNAA3R2 - Stereo Audio Codec, 32-QFN-EP | NXP

The NXP SGTL5000XNAA3R2 is an ultra-low-power stereo audio codec with integrated headphone amplifier, delivering 98 dB SNR DAC performance at only 4 mW for the DAC-to-headphone path, housed in a 32-pin QFN with exposed pad (5x5 mm) package. The IC combines line-in, microphone-in, line-out, headphone-out, and digital audio I/O on a single die, with 24-bit ADC/DAC resolution and 100 dB SNR on the ADC path. Programmable sample rates from 8 kHz to 96 kHz are supported, and an integrated PLL allows clock reuse from an external system reference, reducing overall BOM cost. An audio codec (coder-decoder) is a mixed-signal IC that converts digital audio streams (typically I2S, left-justified, or right-justified) into analog signals for headphones or line outputs while simultaneously digitizing analog microphone or line inputs. The SGTL5000 belongs to the audio codec family, which sits in the broader mixed-signal semiconductor hierarchy of audio ICs, interface ICs, and finally the integrated circuit category. It enables compact portable designs by collapsing the DAC, ADC, headphone driver, and PLL onto one chip. Key features of the SGTL5000XNAA3R2 include a capless headphone output topology that eliminates the need for large DC-blocking capacitors, programmable microphone bias with on-chip reference, and 1.62 V to 3.6 V digital supply operation with 0.9 V to 1.2 V analog core voltage (generated by an internal LDO). Total harmonic distortion plus noise is rated at -80 dB (DAC-to-headphone), and quiescent current consumption is engineered for handsets, tablets, and other battery-powered applications. The exposed thermal pad on the 32-QFN-EP package ensures low thermal resistance for continuous headphone drive. The architecture uses a sigma-delta modulator for both ADC and DAC paths with on-chip digital decimation/interpolation. The integrated PLL accepts a reference clock and synthesizes all internal audio clocks, allowing system designers to feed a single system clock and avoid adding a dedicated audio crystal. Headphone amplification is ground-centered and capless, supporting 16 ohm and 32 ohm loads. Typical applications include portable media players, tablets and e-readers, wearable fitness devices, USB audio dongles, and low-power voice-capture accessories. The codec is also found in industrial human-machine interfaces and consumer single-board computers where compact audio is required. When designing with the SGTL5000XNAA3R2, place the analog decoupling capacitors as close to the AVDD and HPVDD pins as possible, and connect the exposed pad to a clean analog ground. Route I2S and I2C traces away from switching nodes and consider a ferrite bead between DVDD and the system digital supply to prevent digital switching noise from coupling into the analog path. This page synthesizes distributor pricing, NXP and Freescale cross-references, drop-in alternatives, and practical design notes not aggregated in any single datasheet or distributor page, giving engineers a one-stop decision resource.

SGTL5000XNLA3

SGTL5000XNLA3 - Ultra-Low-Power Stereo Audio Codec | NXP

The NXP SGTL5000XNLA3 is an ultra-low-power stereo audio codec with an integrated headphone amplifier, housed in a 20-pin QFN-EP (3x3 mm) package with exposed thermal pad. It delivers 98 dB SNR DAC performance, -80 dB THD+N at headphone output, and consumes only 4 mW for the DAC-to-headphone playback path, forming a complete mixed-signal audio solution in a single die. The device integrates line-level input, microphone input, line output, headphone output, and a digital I/O port supporting I2C and SPI control in a 3 mm x 3 mm footprint suitable for hand-held and wearable products. An audio codec (coder-decoder) is a mixed-signal integrated circuit that converts digital audio streams to analog outputs through a DAC path and converts analog inputs to digital streams through an ADC path. The SGTL5000 sits within the broader hierarchy of audio converters -> audio ICs -> interface ICs -> integrated circuits. By integrating a PLL, a capless headphone driver, and programmable digital filters, the codec reduces external BOM cost and PCB area compared with discrete codec-plus-headphone-amplifier designs. Key features include 98 dB SNR on the DAC path, -80 dB THD+N at headphone output, 4 mW playback power consumption, an integrated PLL that accepts external system clocks, a capless 32 ohm headphone driver, programmable digital volume control, and a 5-band parametric equalizer. The 20-QFN-EP package exposes a thermal pad that keeps junction temperature low during sustained headphone playback, and the I2C/SPI control interface simplifies bring-up with virtually any host microcontroller. Architecturally, the SGTL5000 combines a multi-bit sigma-delta DAC and ADC with an on-chip voltage reference, low-dropout regulators for analog and digital supply domains, and a ground-centered capless headphone amplifier. The integrated PLL supports standard audio sample rates from 8 kHz to 96 kHz and recovers the audio clock from a system reference, eliminating the need for a separate audio crystal in many designs. Typical applications include portable media players, wearable audio devices, IoT speakers, single-board computers (for example, the Teensy Audio Shield ecosystem), gaming headsets, and developer kits that need USB or wireless audio playback with headphone monitoring. The wide host compatibility and low power draw also make it well suited for digital voice assistants and Bluetooth audio post-processing stages. Designers should plan for adequate decoupling on VDDA and VDDIO rails, route the analog and digital grounds as split planes joined at a single point beneath the exposed pad, and follow the NXP reference layout to preserve the 98 dB SNR figure. The headphone output is capless, but the line output requires an AC-coupling capacitor when driving single-ended loads. This page synthesizes verified distributor pricing, datasheet specifications, drop-in alternatives, and practical layout notes not found in the manufacturer datasheet alone, helping engineers shorten the evaluation cycle and avoid common BOM-risk pitfalls when sourcing the 20-pin QFN-EP variant versus the legacy 32-pin QFN.

It supports stereo line-in, microphone-in, line-out, headphone-out and digital I/O through I2C, SPI or I2S serial interfaces, with a power budget of just 4 mW from DAC to headphone output. An audio codec (coder-decoder) is a mixed-signal IC that converts digital audio streams into analog signals for headphones or line outputs and converts analog microphone or line inputs back into digital audio. It sits in the signal chain between a host processor's digital audio bus and the analog audio transducers. The SGTL5000 belongs to the ultra-low-power codec class (codec -> audio converter -> mixed-signal IC -> semiconductor), making it suitable for battery-powered portable products where power and PCB area are at a premium. Key features include an integrated PLL that reuses an external clock to reduce system BOM, capless headphone output that eliminates large AC-coupling capacitors, programmable mic bias, and digital volume controls on every path. The 98 dB SNR exceeds most portable audio requirements while the 4 mW quiescent draw enables hours of playback on small batteries. Hardware gain-ramped transitions eliminate zipper noise during volume changes. The SGTL5000 uses a multi-bit sigma-delta modulator for both ADC and DAC paths with on-chip digital filters and de-emphasis. The integrated charge pump generates a negative rail for the headphone amplifier, allowing true-ground-referenced 0 V output swing without DC blocking caps. A flexible clock tree accepts master clock, bit clock or external PLL reference. Typical applications include portable media players, GPS/navigation devices with voice prompts, wearable fitness audio, Bluetooth/USB headset dongles, and low-power IoT audio endpoints. The 20-QFN-EP footprint also suits space-constrained wearables and embedded boards such as the Teensy audio shield and various SBC platforms. When designing with this device, follow NXP's recommended PCB layout for the exposed pad: stitch vias under the EP for thermal dissipation and ground return, keep analog and digital ground planes split under the IC and stitch at one point. Use low-ESR ceramic decoupling close to each supply pin and route I2S traces impedance-matched and length-matched to avoid jitter.

SI21662-B22-GMR

SI21662-B22-GMR - Dual DVB-S/S2 Satellite TV Demodulator | Skyworks

The Skyworks SI21662-B22-GMR is a dual-channel DVB-S, DVB-S2 and DSS satellite TV digital demodulator integrated into a single 68-pin QFN (8x8 mm) package. Each of the two independent demodulator cores supports QPSK, 8PSK, 16APSK and 32APSK modulation, with symbol rates up to 45 Msps for legacy DVB-S and up to 30 Msps for DVB-S2. The device is intended for satellite set-top box, PVR, and TV front-end designs that must tune two transponders simultaneously for picture-in-picture or dual-record functionality. Host communication is via a standard I2C serial interface (TBC specific address) operating from a single 3.3 V supply, and the part is delivered on 2500-piece tape and reel in the GMR (Pb-free matte-tin, RoHS compliant) finish. A satellite demodulator is a category of baseband signal-processing IC that converts the digitized IF output from a tuner into MPEG transport streams (or LVDS / parallel TS to an external host decoder). It belongs to the broader hypernym hierarchy: demodulator -> tuner/demodulator can -> receiver subsystem -> digital TV front-end -> consumer video SoC ecosystem. Modern DVB-S2 systems additionally apply LDPC forward-error-correction, so an Si2166x family device must pair with a low-noise PLL that meets the phase-noise mask demanded by 32APSK constellations. Key features include dual independent DVB-S/DVB-S2/DSS demodulation channels, 32APSK and 16APSK support for high-efficiency DVB-S2 transponders, integrated LDPC and BCH FEC engines, DiSEqC 1.x and 2.x interface support, and a flexible TS output interface with serial, parallel and LVDS options. An on-chip programmable clock recovery synthesizer removes the need for an external VCXO in most designs, reducing BOM cost. The 68-QFN (8x8 mm) exposed-pad package supports a thermal resistance (theta_JA) suitable for the typical 0.6 W power dissipation of the device under full dual-channel load. The SI21662-B22-GMR uses Skyworks' proprietary dual demodulator core architecture that shares the analog AGC loop and host interface between channels. Each demodulator includes its own channel filter, symbol-rate Nyquist filter, carrier-recovery loop, and LDPC decoder. The device is implemented in a standard CMOS process and supports both legacy DVB-S (QPSK) and the second-generation DVB-S2 standard with multi-level APSK constellations, giving receiver manufacturers a single silicon platform for legacy SD, HD, and UHD satellite transponder decoding. Typical applications include dual-tuner satellite set-top boxes, hybrid satellite/terrestrial DVRs, professional satellite receiver cards, and television sets with built-in DVB-S2 tuners. The dual-channel architecture is particularly suited to watch-and-record scenarios where one tuner is dedicated to a live channel while the second records a different transponder simultaneously. The integrated DiSEqC interface also makes the part a natural fit for multi-LNB dish installations such as motorised DiSEqC 1.2 / 2.x setups. When designing with the SI21662-B22-GMR, provide a clean 3.3 V regulated analog rail (LDO) and short, impedance-controlled IF traces from the tuner output, because the demodulator's symbol-timing recovery is sensitive to phase noise on both the IF and the reference clock. Use a 100 nF decoupling capacitor on every VDD pin and a single 10 uF bulk capacitor on the 3V3 supply pin. This page synthesizes distributor pricing, drop-in Si2166x family alternatives, pinout guidance, and design notes that go beyond what the manufacturer datasheet alone provides for the SI21662-B22-GMR.

SI2400-BS

SI2400-BS 2.4 kbps ISOmodem IC | Skyworks Solutions

The Skyworks Solutions SI2400-BS is a 2.4 kbps ISOmodem system-side interface IC supporting V.21, V.22, V.23, Bell 103, Bell 212A, and V.22bis operation in a 16-pin SOIC package. According to the verified distributor data, it operates from a 3 V to 5.25 V supply and includes an integrated global DAA, capacitive isolation, parallel phone detection, globally compliant line-interface features, and overcurrent protection. These characteristics place the device in the modem interface IC category, a specialized application of interface semiconductors for connecting data equipment to analog telephone networks. The SI2400-BS consolidates legacy serial modem functionality into a compact surface-mount device. Its highest supported data rate is 2400 bps, while V.21 and Bell 103 provide lower-rate operation and V.22, V.23, Bell 212A, and V.22bis provide additional protocol compatibility. The integrated global DAA is significant because it reduces the amount of external telephone-line interface circuitry required. Capacitive isolation separates the line-facing circuitry from the system side, while parallel phone detection supports shared-line or off-hook detection functions. The verified product information identifies the SI2400-BS as a system-side ISOmodem rather than a general-purpose data modem or modern broadband communications controller. Its 16-SOIC body measures 3.90 mm wide in the standard 0.154-inch format, allowing reuse of conventional small-outline PCB land patterns. It is supplied in a tube according to the available package data, making it practical for prototype assembly, small production runs, and legacy telecommunications equipment. Typical uses include legacy fax and data equipment, remote-control systems, industrial telemetry links, point-of-sale terminals, and telecommunications equipment that must retain support for V.21, V.22, V.23, Bell 103, or Bell 212A connections. Because the verified material identifies these standards rather than giving detailed timing, clock, or pin-level electrical limits, engineers should confirm those parameters in the manufacturer datasheet before releasing a new design. The principal design consideration is that a 16-pin SOIC modem must be supported by appropriate telephone-line interface, isolation, power, and signal-conditioning components. Board layout should preserve the isolation boundary and keep sensitive analog line connections physically separated from digital and power-return paths. Input and supply filtering should also follow the manufacturer’s reference implementation when the full datasheet is available. This page consolidates the verified distributor descriptions, package information, protocol coverage, same-family cross-reference results, and practical selection guidance for the SI2400-BS. It also distinguishes documented facts from parameters that still require confirmation from the manufacturer datasheet, helping engineers evaluate this legacy ISOmodem without treating unverified electrical details as guaranteed specifications.

Typical applications include embedded telephone-line modems, industrial data links, point-of-sale equipment, legacy fax or terminal interfaces, telecom test equipment, and communication modules requiring V-series or Bell 212A compatibility. System designers should verify the exact pinout, line-side circuitry, isolation requirements, and protocol implementation against the manufacturer datasheet before production release. For PCB design, place the SOIC close to the telephone-line interface and keep sensitive analog and digital return paths appropriately separated. Provide stable supply bypassing and confirm the selected DAA programming values for the target country. Because this is an interface IC rather than a power semiconductor, SOA data is not applicable.

Its multi-standard support allows equipment designers to configure one controller for different analog line speeds. The package is identified as a 16-pin SOIC, also described as SOP with gull-wing leads and a commercial temperature grade. Typical uses include legacy fax machines, point-of-sale terminals, industrial data collectors, telephone answering equipment, remote-access systems, and embedded PSTN gateways. These applications benefit from the integrated DAA, backward-compatible 300 to 2400 bps operation, and programmable international line interface. Designers should verify country-specific line parameters, isolation requirements, hook-switch behavior, and supported signaling protocols before release. Because the SI2401-FSR is a mature legacy interface, current lifecycle and availability should be reconfirmed before new production commitments. LCSC lists the SI2401-FSR as in stock with pricing from $2.6067 as of 2026-10-23.

The related SI2404 family supports communication rates extending from 2,400 bps to the V.92 class at 56,000 bps when paired with an appropriate line-side companion device. An ISOmodem is a modem controller integrated circuit designed for data communication over telephone, analog, or other limited-bandwidth connections. It combines modulation, data handling, call-control signaling, and line-interface functions into a compact device. A system-side ISOmodem normally works with a line-side counterpart, allowing the two devices to divide the functions required for a complete analog data modem connection. The SI2404-D-FS supports the principal V-series and Bell modem formats identified in the manufacturer documentation, including V.21, V.22, V.23, V.29, Bell 103, and Bell 212A. Related family documentation also identifies V.44, V.42, V.42bis, MNP2-5, automatic rate negotiation, Fast Connect, and Type I and Type II caller-ID decoding. These capabilities make the family applicable to legacy data equipment, embedded communication modules, fax systems, and industrial interfaces requiring standards-compatible modem signaling. As a 2.4 kbps system-side modem IC, the SI2404-D-FS emphasizes compact implementation and compatibility with established modem protocols. Its 16-pin SOIC package provides a small surface-mount footprint, while the protocol mix allows operation with older terminals, fax machines, remote-management equipment, and telephone-network interfaces. The maximum 56,000 bps family capability depends on the selected line-side companion and does not mean that every operating mode of the SI2404-D-FS itself runs at that rate. Typical implementations include embedded analog modems, fax-modem modules, industrial remote terminals, point-of-sale equipment, telecommunications test equipment, and legacy data-collection systems. In each application, the correct line-side IC, isolation boundary, analog termination, and network interface must be selected together because the SI2404-D-FS represents the system-side portion of the modem chipset. When laying out the PCB, place the SI2404-D-FS close to the companion modem and analog-network interface components. Follow the manufacturer pin-description table for supply, ground, clock, control, and analog connections, and preserve the specified decoupling arrangement. Component population and timing values should be selected from the SI2404 family documentation rather than estimated from unrelated modem designs. This page combines protocol identification, package and rate details, drop-in comparison guidance, and practical integration notes to accelerate component selection. Review the complete SI2404 family datasheet and your system-level modem requirements before releasing a production design.

The integrated DAA reduces the number of external telephone-line interface components needed in a connected product. The SI2439-A-FM is identified as a V.34 and V.92 modem solution with a stated data rate of 33.6 kbps. Its 38-QFN construction is intended for compact surface-mount equipment, while the exposed-pad package arrangement supports board-level thermal management. The 3 V to 3.6 V operating range allows the modem circuitry to operate from a regulated low-voltage rail in embedded communications equipment. This part belongs to Skyworks' ISOmodem family, where modulation, data pumping, line-interface functions, and a global DAA are consolidated into one mixed-signal semiconductor. Consolidation can reduce external component count and board area compared with a discrete modem implementation. The package also reduces interconnect complexity by placing the modem functions and their required land pattern on a single surface-mount device. Typical uses include embedded asynchronous modems, data communications equipment, telephone-network interfaces, industrial data links, and legacy WAN connectivity equipment. Selection is appropriate when a design specifically requires V.34 or V.92 compatibility, a 33.6 kbps modem channel, and the SI2439-A-FM's integrated global DAA. Host software, line-interface support, and regulatory certification must be evaluated as part of the complete modem subsystem. The principal design consideration is the exposed-pad footprint. Place the device according to the manufacturer's land pattern, provide all supply and ground connections, and follow the datasheet's recommended decoupling and thermal-layout requirements. Because modem performance depends on the surrounding telephone interface and implementation, validate conducted emissions, line behavior, and interoperability in the final equipment rather than relying only on individual IC measurements. This page consolidates the verified product identity, package information, modem standards, supply range, and sourcing information into one engineering reference. It also distinguishes confirmed device attributes from details that require direct review of the manufacturer datasheet, including the complete pin table, clocking requirements, line-interface values, and approved application configurations.

The SI2456-FT also provides more than 5000 V capacitive isolation, parallel phone detection, automatic rate negotiation, and a globally compliant line interface. An ISOModem chipset is an integrated data-over-voice modem optimized for telephone and wide-area-network endpoints. Within the broader modem hierarchy, it combines signaling functions, data-link protocols, and telephone-line interface circuitry in one IC. This integration reduces the number of external interface components required in designs that need asynchronous or synchronous data transfer over an analog phone line. The principal features of the SI2456-FT include a 3 V to 3.6 V supply range, 56 kbps maximum data rate, V.42bis and MNP2-5 error correction, automatic rate negotiation, parallel phone detection, and overcurrent protection. Its lead-free 24-TSSOP package supports conventional surface-mount assembly while exposing the device in the system-side modem format identified by the SI2456-FT ordering code. Technically, the device combines modem signal processing with an integrated global DAA. The DAA provides the telephone-line termination and isolation functions required for connected-line operation, while protocol support covers the principal ITU-T and Bell modem recommendations listed for the component. Automatic rate negotiation allows the modem to select an appropriate bearer rate from the capabilities of the connected endpoint, and V.42bis/MNP2-5 support improves transmission reliability on noisy lines. Typical uses include point-of-sale terminals, industrial data-collection equipment, remote telemetry systems, embedded telephone-network access, and legacy equipment requiring a Bell or ITU-T modem connection. The SI2456-FT is particularly appropriate where a compact surface-mount solution and integrated line isolation are more important than a high-speed broadband data interface. Designers should verify the exact board layout, external network-interface components, and firmware requirements against the manufacturer datasheet before production. Because this is an integrated line-side modem chipset, PCB creepage, isolation, grounding, and telephone-network compliance require careful implementation; substitution should never be based on package appearance alone. This page consolidates verified specifications, sourcing information, replacement guidance, and design considerations for the SI2456-FT. It also distinguishes a documented same-package family alternative from unverified substitutes, helping engineers make a defensible legacy-modem sourcing decision.

The commercial-temperature rating supports indoor telecom, industrial control, fax, and data-communication equipment. Technically, the SI2457-C-FT is a system-side modem solution rather than a general-purpose transceiver. Its protocol support allows a host processor to establish modem connections across PSTN or equivalent line systems. The built-in phase-locked loop supports stable symbol timing, and the integrated telephone-interface functions simplify the analog line path. Designers should still account for line protection, regional impedance requirements, coupling components, and the complete reference circuit described in the manufacturer data sheet. Typical uses include legacy fax equipment, remote-access terminals, industrial monitoring links, embedded telephone interfaces, point-of-sale systems, and communications equipment that must support both V.21-class low-speed data and V.90-class 56 kbps operation. The broad protocol set makes the IC useful where interoperability with older telephone infrastructure matters more than raw data throughput or a modern packet-based interface. A critical design consideration is the telephone-line interface. The manufacturer data sheet specifies the external component values, isolation network, hook and phone-detection circuitry, and layout constraints required for reliable operation. Keep sensitive line-side routing compact, provide the specified protection network, and observe the required creepage and clearance distances for the intended installation class. This product page consolidates the SI2457-C-FT electrical characteristics, package information, protocol capabilities, application guidance, and confirmed same-package alternatives. It also highlights practical distinctions among closely related Si2457-family devices so engineers can assess footprint reuse, modem features, and implementation constraints before placing a part on a new design.

Typical uses include legacy modem pools, industrial data communication equipment, telephone-line monitoring systems, point-of-sale terminals, and embedded access products requiring Bell or V-series compatibility. Because V.92 modem designs include analog telephone-line characteristics, component selection must account for the external line interface, isolation, filtering, ring detection, and the host-side communication requirements of the complete system. For a new PCB, use the 16-pin SOIC footprint and follow the manufacturer pin-description table and typical application circuit. Do not assume that footprint compatibility alone guarantees functional interchangeability. Review clock requirements, supply sequencing, interface signals, country-specific line-network behavior, and external analog components before transferring an existing design to SI2493-C-FS. This product page combines the manufacturer data-sheet information, interface and package characteristics, protocol coverage, verified sourcing records, and practical implementation guidance. It also distinguishes explicitly documented replacements from merely similar modem ICs so engineers can assess PCB reuse, protocol support, and system-level risk before making a sourcing decision.

SI3000-C-FS

SI3000-C-FS - 16-Bit Voice Codec | Skyworks Solutions

Skyworks Solutions SI3000-C-FS is a 16-bit voice-band audio codec with a serial interface, programmable input and output gain or attenuation, microphone bias, a handset hybrid circuit, and output drive for 32-ohm headphones. The device operates from 3 V to 5.25 V and is packaged in a 16-pin SOIC. A voice-band audio codec converts analog voice signals into digital data for transmission and reconstructs digital audio into an analog signal for playback. The SI3000-C-FS integrates several telephone-interface functions that otherwise require separate components, including microphone amplification, output drive, microphone bias, and handset hybrid support. Its 16-bit serial interface allows it to connect with compatible modem and data-access-arrangement devices. Programmable input and output gain or attenuation provide control over signal levels in analog voice paths. The integrated microphone bias circuit supports microphone-based input stages, while the output driver is specified for 32-ohm headphones. These functions reduce the number of external analog components required in a voice-band interface. The SI3000 family is intended for voice-band equipment, including ISOmodem and digital access equipment. The SI3000-C-FS can connect directly to Si3035, Si3044, and Si3056 North American and international DAA chipsets through the serial interface, allowing an analog voice path to be paired with an established line-interface chipset. Supply-voltage operation from 3 V to 5.25 V makes the codec usable in 3.3 V and 5 V systems. The listed operating-temperature range is 0 C to 70 C. Because this is a mixed analog-and-serial-interface device, correct grounding, supply decoupling, clock implementation, and layout of the voice path directly affect signal integrity and audio performance. For a new design, use the manufacturer pin-description table and recommended application circuit when assigning PCB tracks, setting gain, and selecting support components. Pay particular attention to analog and digital return paths, the microphone-bias connection, and the output-drive network. The 16-pin SOIC footprint supports conventional surface-mount assembly but requires adequate copper and thermal considerations for reliable soldering. This page combines device capabilities, application fit, sourcing guidance, and practical design notes to help engineers evaluate the SI3000-C-FS for compact voice-band systems. It also distinguishes verified compatibility from unknown replacement options so procurement decisions can be based on package, interface, and electrical requirements rather than MPN similarity alone.

SI3000-C-GS

SI3000-C-GS - 16-Bit Voice-Band Audio Codec | Skyworks

The Skyworks Solutions Inc. SI3000-C-GS is a 16-bit voice-band audio codec with 84 dB ADC dynamic range, 84 dB DAC dynamic range, and 4–12 kHz sample rates in a 16-SOIC package. It integrates a 30 dB microphone preamplifier, programmable input and output gain or attenuation, microphone bias, handset hybrid circuitry, and output drive for 32 Ω headphones. A voice-band codec is a specialized audio interface that converts analog microphone or line-level signals into a digital serial stream and converts digital audio back into an analog output. Within the hierarchy of audio codecs, line codecs, audio interface ICs, and interface semiconductors, it concentrates several telephone and modem signal-chain functions into one device. Its narrowband sampling range is intended for speech rather than hi-fi music. The SI3000-C-GS provides one ADC and one DAC, both using 16-bit resolution. Programmable input and output gain or attenuation gives the system designer control over signal levels, while the 30 dB microphone preamplifier supports direct microphone conditioning. The integrated bias circuit reduces external microphone-support requirements, and the headset driver is specified for 32 Ω loads. Integration is a central advantage because the codec combines the analog voice interface, conversion functions, and telephone-support circuitry. According to the manufacturer datasheet, the device can connect directly with Si3034, Si3035, Si3044, and Si3056 data-access arrangements and chipsets. These interfaces support voice-band modem and telephone equipment where board area and component count are important constraints. Typical applications include voice-band modems, telephone interface boards, handsets, speakerphones, voicemail equipment, and data-access adapters. The 16-SOIC package also makes the SI3000-C-GS suitable for designs that require conventional surface-mount assembly rather than a high-density land grid array. When designing around this codec, verify the required analog supply, digital interface voltage, sampling clock, and serial device configuration against the manufacturer pin descriptions and application guidance. Decoupling, grounding, and microphone-bias layout remain critical because they directly influence noise, distortion, and voice intelligibility. This product data combines the confirmed electrical characteristics, package information, interface functions, application fit, and design considerations needed to evaluate the SI3000-C-GS for a voice-band audio signal chain.

SI3000-KS

SI3000-KS - 16-Bit Voice Codec | Skyworks Solutions

Skyworks Solutions SI3000-KS is a 16-bit voice-band interface codec with one ADC channel and one DAC channel, supporting sample rates from 4 kHz to 12 kHz in a 16-pin SOIC package. The verified listing identifies 84 dB ADC dynamic range, 84 dB DAC dynamic range, a 30 dB microphone preamplifier, programmable input gain or attenuation, and programmable output gain or attenuation. It is intended for voice-band audio systems requiring integrated conversion and microphone or speaker drive functions. The distributor data also identifies the SI3000-KS as a leaded interface codec and reports that Skyworks recommends the Si3000-C-FS datasheet for current design work. This means lifecycle status should be confirmed before new production commitments, although the SI3000-KS remains listed by distributors. A voice-band codec is an audio interface integrated circuit that converts analog microphone or line-level signals into digital PCM data and converts digital audio back into an analog output. In the broader device hierarchy, the SI3000-KS belongs to audio codecs, interface ICs, signal-conversion devices, and semiconductor components. Its one-ADC and one-DAC architecture is suitable for compact telephony, communications, embedded voice, and audio-assistance designs where a dedicated low-bandwidth audio path is required. The 4 kHz to 12 kHz sample-rate range targets narrow voice bandwidth rather than full-spectrum hi-fi audio. The main engineering benefits are the stated 84 dB conversion dynamic range, integrated microphone and speaker-drive support, and programmable analog gain controls. Input gain or attenuation helps match microphone levels to the converter, while output gain or attenuation helps condition the playback signal before the speaker amplifier. The 30 dB microphone preamplifier provides additional headroom for weak microphone sources. Because the verified data does not provide supply voltage, clock requirements, control-interface details, absolute maximum ratings, or thermal data, those values must be obtained from the manufacturer datasheet before final schematic or PCB approval. Use the SI3000-KS when the design specifically needs a narrowband voice codec with integrated ADC, DAC, microphone preamplification, and programmable gain. Suitable application directions include telephone handsets, intercom systems, industrial voice terminals, automotive voice interfaces, and embedded communication modules. The automotive positioning appears in distributor descriptions, but qualification status and exact environmental requirements are not independently established by the supplied data and therefore remain unknown. A design must also verify that the required sample rate, serial interface, audio levels, power rails, and external components match the device datasheet. The principal design consideration is lifecycle risk. Mouser states “Leaded - Not recommended for new designs, see Si3000-C-FS datasheet,” while DigiKey lists SI3000-KS for purchase. Engineers should therefore treat the SI3000-KS as a potentially legacy or transition-related device and compare it with the recommended current family before committing a new design. The exact pinout is not reproduced in the supplied verified snippets, so pin-level wiring must be confirmed from the official manufacturer datasheet. This page combines the verified distributor classification and specifications with procurement context and design guidance without inventing missing electrical parameters. This page synthesizes distributor listings, lifecycle notices, codec specifications, replacement guidance, and practical application considerations. It distinguishes verified facts from unavailable parameters, highlights the Skyworks recommendation concerning Si3000-C-FS, and avoids treating a distributor availability statement as proof of long-term design support.

SI3010-FS

SI3010-FS - 2.4 kbps Global DAA | Silicon Labs

The Silicon Labs SI3010-FS is a 2.4 kbps direct access arrangement integrated with a global DAA and supplied in a 16-pin SOIC package. It operates from a 3 V to 3.6 V supply, supports a 0°C to 70°C temperature range, and is intended for telephone-line interface and ISOmodem applications. The SI3010-FS combines the line-side signaling functions of a direct access arrangement with the digital interface requirements of a V.22bis ISOMODEM system. A direct access arrangement, or DAA, is the line-side interface between a modem data terminal and a public switched telephone network. It converts analog line conditions into signals that can be processed by modem circuitry while providing the required isolation, hook-state detection, dialing, and line-current handling. A global DAA is designed to support internationally configurable telephone-line behavior rather than a single country-specific line interface. The SI3010-FS provides a 2.4 kbps data rate and operates from 3 V to 3.6 V, making it suitable for legacy V.22bis-class data communication equipment. Its 16-pin SOIC package is a surface-mount format suitable for automated assembly, and the reel configuration supports production feeding. The documented operating range of 0°C to 70°C identifies the SI3010-FS as a commercial-temperature device. The integrated DAA reduces the number of external line-interface functions required in a complete modem design. This can simplify the printed-circuit-board layout while preserving a standardized telephone-line interface. Because the part belongs to the Si2401 and Si2404 ISOmodem families, it is particularly relevant to designs requiring a line-side DAA paired with established modem controller or codec functionality. Typical uses include 2400 bps modem hardware, fax and data terminal equipment, industrial data links operating through telephone networks, and legacy communications controllers that require a globally programmable DAA. The SI3010-FS is also useful when a completed modem design must be maintained with an established 16-pin SOIC footprint and 2.4 kbps class performance. Designers should verify the complete SI3010 or Si240x companion-device arrangement because the DAA also requires suitable line-interface components and an appropriate host or modem companion. PCB layout must preserve the manufacturer's recommended analog and digital partitioning, while component selection must account for the telephone network's voltage and current requirements.
