CS8416-CZZR

Audio Special Purpose Overview

The CS8416-CZZR is a monolithic CMOS digital audio receiver manufactured by Cirrus Logic Inc. It receives and decodes one of eight stereo pairs of digital audio data according to IEC60958, S/PDIF, EIAJ CP1201, or AES3 interface standards. The device supports sampling rates from 32kHz to 192kHz and operates on a 3.3V to 5V supply voltage. It features a serial digital audio output port and comprehensive control via selectable pins in Hardware Mode or through an SPI/I²C control port in Software Mode. Channel status data are assembled in buffers for easy read access.

Audio Special Purpose Feature Summary

• Supports up to 8-channel digital audio input with 8:2 multiplexing capability
• Integrates low-jitter clock recovery mechanism for clean signal reconstruction
• Configurable 3-wire serial digital audio output port
• Three general-purpose output (GPO) pins for flexible signal routing

Audio Special Purpose Applications

• Audio/Video receivers
• Multimedia speakers
• Digital mixing consoles
• Set-top boxes

Audio Special Purpose Procurement Notes

This component is marked as Obsolete/End-of-Life (EOL). Distributor records indicate the product was declared obsolete around June 2021 with a Last Time Buy date in July 2022. Verify availability through remaining stock or authorized distributors only; new production is not guaranteed.

Audio Special Purpose Selection Notes

Select this component when high-resolution digital audio reception up to 192kHz is required. It is suitable for designs needing multi-channel input handling and flexible output configuration. Compare against the CS8416-CNZR if a QFN package is preferred over the TSSOP form factor. Consider the CS8415A for applications requiring lower sampling rate support but different pinout constraints.

Audio Special Purpose Part Context

The CS8416 series represents Cirrus Logic's solution for professional and consumer digital audio interfacing. The CZZR variant specifically denotes the TSSOP-28 package in a tape and reel configuration. This part belongs to a broader family that includes transmitters like the CS8406 and alternative receiver packages such as the CNZR. It serves as a core component for decoding standard digital audio streams into usable formats for downstream processing.
