CS8406-DSZR

Audio Special Purpose Overview

The CS8406-DSZR is a monolithic CMOS digital audio interface transmitter manufactured by Cirrus Logic. It encodes and transmits audio data in compliance with AES3, IEC 60958, S/PDIF, and EIAJ CP1201 standards. The device accepts audio and digital data via a configurable three-wire serial input port, multiplexes the signals, and drives them onto a cable. It supports sampling rates from 8 kHz to 192 kHz and operates on a single +3.3 V or +5.0 V digital supply voltage. Channel status and user bit data are managed through SPI or I²C microcontroller interfaces.

Audio Special Purpose Feature Summary

• Supports AES3, IEC 60958, S/PDIF, and EIAJ CP1201 transmission standards
• Configurable three-wire serial digital audio input port
• On-chip channel status and user bit buffer memories for block-sized updates
• Microcontroller write access to channel status and user bit data via SPI or I²C

Audio Special Purpose Applications

• Digital audio interfacing systems
• Audio transmitters requiring AES/EBU or S/PDIF compatibility

Audio Special Purpose Procurement Notes

The CS8406-DSZR is marked as 'Obsolete' (End-of-Life) by the manufacturer. Distributor listings indicate it may be available in Tape & Reel packaging, while the base part CS8406-DSZ is often listed in Tube packaging. Verify availability and lead times carefully due to its lifecycle status.

Audio Special Purpose Selection Notes

Select this component for applications requiring a standalone digital audio transmitter compatible with major professional and consumer standards. The device supports frame rates up to 192 kHz and allows direct access to channel status bits without a microcontroller in standalone mode. Note that this part is obsolete; consider replacement options if long-term supply is required.

Audio Special Purpose Part Context

The CS8406 series consists of high-performance digital audio interface transceivers designed for professional and consumer audio equipment. The CS8406 specifically functions as a transmitter, encoding parallel audio data into serial formats suitable for long-distance transmission over coaxial cables. It is part of a broader family including receiver variants like the CS8416.
