CS8416-CSZR

Audio Special Purpose Overview

The CS8416-CSZR is a monolithic CMOS digital audio interface 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 standards. The device features an 8:2 S/PDIF input multiplexer, low-jitter clock recovery, and flexible serial digital output ports supporting sample frequencies from 32 kHz to 192 kHz. It operates with +3.3 V analog and digital supplies, and a +3.3 V or +5.0 V logic supply. The component is housed in a 28-SOIC package and supports I²C and SPI control interfaces for comprehensive configuration.

Audio Special Purpose Feature Summary

• Supports IEC60958, S/PDIF, EIAJ CP1201, and AES3 digital audio standards
• Integrates an 8:2 S/PDIF input multiplexer with selectable hardware mode
• Features low-jitter PLL clock recovery mechanism for clean signal reconstruction
• Provides three general-purpose outputs (GPO) for customizable signal routing

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 'CSZR' corresponds to the 28-SOIC package variant when sourcing. Confirm that the commercial grade operating temperature range (-10°C to +70°C) meets system requirements. Ensure power supply decoupling adheres to the datasheet recommendations for AGND and DGND separation. Note: This product family has been declared Obsolete/End-of-Life; check distributor availability carefully.

Audio Special Purpose Selection Notes

Select this component for designs requiring multi-input digital audio reception with high channel status data access. The CS8416 supports both software-controlled (I²C/SPI) and standalone hardware modes. Ensure the host system can accommodate the required 3.3V/5.0V logic levels and that the PCB layout allows for proper differential input termination and PLL filter capacitor placement near the FILT pin.

Audio Special Purpose Part Context

The CS8416 belongs to the Cirrus Logic CS84xx series of digital audio interface receivers. The CSZR suffix specifically denotes the 28-pin SOIC package version, distinct from the QFN or TSSOP variants. This part is designed for high-performance audio applications where jitter attenuation and robust channel status handling are critical.
