CS8427-CS - 96 kHz Stereo Digital Audio Transceiver | Cirrus Logic
部品番号: CS8427-CS ✓ 生産中CS8427-CS 概要
A digital audio transceiver is an interface IC that accepts digital audio signals, manages the associated clock and control information, and provides corresponding digital outputs. In the broader signal-chain hierarchy, the CS8427-CS belongs to the digital audio interface family within audio and communications ICs, rather than to analog amplifiers or conventional power-management devices.
The verified manufacturer information identifies AES3 inputs and outputs, serial digital audio input and output paths, and a 4-wire microcontroller control interface. The control port supports communication with an external controller, while the digital audio paths provide the core conversion and routing function. The CS8427 family is documented in 28-pin SOIC and TSSOP packages, with commercial and automotive temperature-grade variants listed in the manufacturer datasheet listing.
The CS8427-CS is particularly relevant to professional audio, consumer audio, and digital-audio equipment designs that require transparent handling of digital audio streams. Its 96 kHz designation identifies the intended digital audio operating class, while the combination of AES3 and serial audio connections allows the device to sit between source and destination interfaces. The 4-wire control port also supports configuration and status monitoring by a host microcontroller.
When designing a board around the CS8427-CS, verify the exact pin function, supply requirements, clock topology, and control-port implementation against the manufacturer datasheet before layout release. The verified distributor result confirms the 28-SOIC package, but the supplied snippets do not expose a complete pin table, so individual pin assignments should be taken directly from the CS8427 datasheet rather than inferred from the package designation.
This page combines verified distributor and manufacturer-datasheet references, same-family replacement data, package information, and practical selection guidance. It is intended to help engineers identify the correct CS8427-CS ordering code and assess whether a same-family CS8427 variant is appropriate for a production redesign.

主な用途
CS8427-CS の用途: 6 件s: Digital Audio Routing and Format Conversion, Professional Digital Audio Equipment, Multichannel Audio Processor, Embedded Audio System Interface, Consumer Digital Audio Source Equipment, Digital Audio Interface Evaluation and Bring-Up.
Digital Audio Routing and Format Conversion
The CS8427-CS is appropriate for a digital audio router that must move streams between AES3 and serial digital audio endpoints. Its verified feature set includes AES3 inputs and outputs, serial digital audio inputs and outputs, and a 4-wire microcontroller control port, allowing a host processor to configure operating conditions and monitor device status. The 96 kHz designation supports high-rate digital audio designs, while the 28-SOIC package simplifies assembly where a through-hole-style digital audio IC is preferred. Before finalizing the board, confirm the exact clock requirements, input/output format support, and electrical limits in the manufacturer datasheet.
おすすめ
Professional Digital Audio Equipment
Professional studio and broadcast equipment can use the CS8427-CS to bridge AES3 sources with serial digital audio sections. Its stereo digital-audio transceiver description and separate AES3 and serial paths reduce the need for parallel glue logic, while the 4-wire microcontroller port supports host-controlled configuration. The part is identified as a 96 kHz device, making it relevant to high-resolution professional audio paths. Board bring-up should verify clock routing, digital-amplitude compatibility, and the control-port timing specified in the CS8427 datasheet.
おすすめ
Multichannel Audio Processor
The CS8427-CS can sit inside a multichannel audio processor as the interface between incoming digital sources and downstream serial audio converters. AES3 inputs accept framed digital audio, serial outputs distribute the selected stream, and the 4-wire control interface permits register configuration from an embedded controller. Its 28-SOIC package provides a practical option for equipment that does not require the smallest possible TSSOP footprint. Exact channel routing and supported sample-rate combinations must be confirmed from the manufacturer data because those detailed values are not exposed in the supplied search excerpts.
おすすめ
Embedded Audio System Interface
An embedded audio system can use the CS8427-CS where an MCU or DSP requires a configurable digital-audio routing stage. The documented 4-wire port includes chip select, bit clock, data input, and data output signals, supporting register access from a host controller. AES3 and serial digital audio paths provide interface flexibility, while the 96 kHz product designation targets high-rate operation. The implementation must pay close attention to signal grounding, digital trace impedance, and clock-source cleanliness because the supplied references identify the interfaces but not the complete board-layout recommendations.
おすすめ
Consumer Digital Audio Source Equipment
The CS8427-CS is suitable for consumer digital-audio source equipment that accepts professional-style digital inputs and must present them to a serial digital audio converter. AES3 inputs provide a direct framed-audio entry point, while the serial output path supports downstream converters or DAC sections. The 4-wire microcontroller port allows the host to configure operating state and report status. Because the device is a transceiver rather than a converter, a separate DAC or audio codec remains necessary for analog output generation, and the manufacturer datasheet should be used to verify supported formats and clock modes.
おすすめ
Digital Audio Interface Evaluation and Bring-Up
The CDB8427 customer demonstration board provides a practical way to evaluate the CS8427 before integrating it into production hardware. Engineers can use the documented AES3, serial audio, and 4-wire control interfaces to verify signal routing and host communication in a controlled platform. The CS8427-CS's 28-SOIC package is also useful for comparing hand-soldered prototypes with the manufacturer's evaluation environment. Final schematic and layout work should nevertheless be based on the production datasheet, including recommended decoupling, clock topology, and signal-termination details that are not present in the supplied snippets.

設計ノート
Route AES3, serial digital audio, and clock signals as controlled-impedance digital nets with continuous return paths beneath the drivers and receivers. Keep the 4-wire control-port traces away from clock and audio nets where practical, and place pull-up or pull-down terminations at the device rather than at the controller when the datasheet specifies them. The supplied excerpts identify the interfaces but do not publish trace-length or impedance limits, so use the manufacturer layout guidance rather than relying on generic digital-design values.
Build the supply network with local high-frequency bypass capacitance at the device and separate the digital-audio return path from noisy analog or switching sections. Because the verified snippets do not expose the CS8427-CS supply-voltage range, quiescent current, or recommended capacitor values, those values must be taken from the manufacturer datasheet. Confirm that the chosen regulator has adequate headroom for the device's absolute maximum rating before defining the power tree, and validate supply ripple at the pins during analog-clock and digital-output switching.
Do not substitute a CS8427 ordering suffix solely from its similarity to CS8427-CS. The verified cross-reference confirms CS8427-CSR, CS8427-CSZR, and CS8427-CZZ as family candidates, while the family is offered in both 28-pin SOIC and 28-pin TSSOP packages and commercial and automotive grades. Validate package dimensions, pinout, temperature grade, and control behavior against the ordering table before treating any candidate as a drop-in replacement.
コンプライアンス情報
The supplied verified excerpts confirm commercial and automotive temperature-grade options in the CS8427 family but do not state material-compliance declarations for the CS8427-CS ordering code. Automotive temperature capability is not treated as proof of AEC-Q100 qualification.
