CS8406-CSZR

Audio Special Purpose Overview

The CS8406-CSZR is a monolithic CMOS digital audio interface transmitter manufactured by Cirrus Logic. It encodes and transmits audio data compliant with AES3, IEC60958, S/PDIF, and EIAJ CP1201 standards. The device accepts audio and digital data via a configurable three-wire serial input port, multiplexes it, and drives the signal onto a cable using an on-chip differential line driver. It supports frame rates from 8 kHz to 192 kHz and operates on a +3.3 V or 5.0 V digital supply. Channel status and user bit data are managed through SPI or I²C microcontroller interfaces or direct pin access in standalone mode.

Audio Special Purpose Feature Summary

• Complete compatibility with EIAJ CP1201, IEC-60958, AES3, and S/PDIF transmission standards
• On-chip channel status and user bit buffer memories enabling block-sized updates
• Flexible three-wire serial digital audio input port supporting up to 192 kHz frame rate
• Integrated CRC code and parity bit generation for data integrity
• Standalone mode allows use without a microcontroller

Audio Special Purpose Applications

• A/V Receivers
• CD-R and DVD Receivers
• Digital Mixing Consoles
• Set-top Boxes
• Computer Audio Systems
• Automotive Audio Systems

Audio Special Purpose Procurement Notes

Verify the package type matches the required 28-SOIC form factor (indicated by 'CSZ'). Confirm that the Tape & Reel (TR) packaging aligns with automated surface-mount assembly requirements. Ensure the operating temperature range of -10°C to 70°C meets the environmental specifications of the target application. Check for RoHS compliance if restricted substances are a concern.
