CS8416-DNZR

Audio Special Purpose Overview

The CS8416-DNZR 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 a serial digital audio output port and comprehensive control via SPI or I²C interfaces. It operates with +3.3V analog and digital supplies, and a +3.3V or +5.0V logic supply. The component supports sample frequencies from 32 kHz to 192 kHz and is housed in a 28-QFN (5x5) package with exposed pad.

Audio Special Purpose Feature Summary

• Includes an 8:2 S/PDIF input multiplexer for flexible signal routing
• Features low-jitter clock recovery mechanism for clean recovered clocks
• Provides three general-purpose outputs (GPO) for configurable signal routing

Audio Special Purpose Applications

• A/V receivers
• DVD/CD players
• Digital mixing consoles
• Set-top boxes

Audio Special Purpose Procurement Notes

The CS8416-DNZR is listed as Obsolete/Not Recommended for New Designs (NRND). Distributors such as DigiKey list the part status as 'Obsolete'. Designers should verify current stock availability and consider replacement strategies due to end-of-life status.

Audio Special Purpose Selection Notes

Select the CS8416-DNZR for applications requiring automotive temperature ratings (-40°C to +85°C). Ensure the design accommodates separate VA (+3.3V), VD (+3.3V), and VL (+3.3V/+5.0V) power supplies. Verify that the PCB layout supports the 28-VFQFN exposed pad package for adequate thermal dissipation and grounding.

Audio Special Purpose Part Context

The CS8416 series includes Commercial grade variants (e.g., CS8416-CNZR) operating from -10°C to +70°C. The DNZR suffix specifically denotes the Automotive grade version with extended temperature capabilities. All variants share the same functional architecture but differ in qualification and environmental specifications.
