CS8416K-CZZ

Audio Special Purpose Overview

The CS8416K-CZZ is a monolithic CMOS digital audio interface receiver manufactured by Cirrus Logic. It decodes stereo audio data from eight input pairs according to IEC60958, S/PDIF, EIAJ CP1201, and AES3 standards. The device operates with a +3.3V analog supply (VA), a +3.3V digital core supply (VD), and a logic supply (VL) of either +3.3V or +5.0V. It supports sample frequencies ranging from 32 kHz to 192 kHz and features low-jitter clock recovery. The component is housed in a 28-TSSOP surface-mount package and functions within an ambient temperature range of -10°C to +70°C.

Audio Special Purpose Feature Summary

• Supports IEC60958, S/PDIF, EIAJ CP1201, and AES3 digital audio interface standards
• Integrates an 8:2 S/PDIF input multiplexer for flexible signal routing
• Includes three general-purpose outputs (GPO) for configurable signal assignment
• Features auto-detection of compressed audio streams and CD Q sub-code decoding

Audio Special Purpose Applications

• A/V receivers
• CD-R and DVD receivers
• Multimedia speakers
• Digital mixing consoles
• Set-top boxes

Audio Special Purpose Procurement Notes

Verify the specific suffix 'CZZ' against the manufacturer's current ordering guide to confirm the exact package type and commercial grade specifications. Confirm that the required voltage levels align with the specified VA, VD, and VL ranges before finalizing procurement.

Audio Special Purpose Selection Notes

Select this component for designs requiring multi-standard digital audio reception without external DSP processing. Ensure the system design accommodates the separate VA, VD, and VL power domains. Verify that the 28-TSSOP footprint matches the PCB layout constraints and thermal requirements for the commercial operating temperature range.

Audio Special Purpose Part Context

This part belongs to the CS8416 series of digital audio receivers. It is designed as a standalone solution for consumer and professional audio equipment, eliminating the need for dedicated microcontrollers in hardware mode configurations while offering full software control via SPI or I²C interfaces.
