CS8406-IZ

Audio Special Purpose Overview

The CS8406-IZ 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 flexible three-wire serial input port, multiplexes the signals, and drives them onto a cable using an on-chip differential line driver. It supports frame rates up to 192 kHz.

Audio Special Purpose Feature Summary

• Complete compatibility with EIAJ CP1201, IEC-60958, AES3, and S/PDIF standards
• Flexible 3-wire serial digital audio input port
• On-chip channel status and user bit buffer memories allow block-sized updates
• Microcontroller write access to Channel Status and User bit data
• On-chip differential line driver
• Generates CRC codes and parity bits
• Standalone mode allows use without a microcontroller
• Supports sampling rates up to 192 kHz

Audio Special Purpose Applications

• A/V receivers
• CD-R and DVD receivers
• Digital mixing consoles
• Effects processors
• Set-top boxes
• Computers
• Automated audio equipment

Audio Special Purpose Procurement Notes

The 'IZ' suffix indicates a TSSOP package variant (typically 28-TSSOP). Verify specific voltage requirements: the datasheet specifies +3.3V or +5.0V for both Digital Supply (VD) and Digital Interface (VL). Confirm availability as this component may be subject to lifecycle changes common with legacy audio ICs.
