CS8416-CNZR

Audio Special Purpose Overview

The CS8416-CNZR 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 the IEC60958, S/PDIF, EIAJ CP1201, or AES3 interface standards. The device features an 8:2 S/PDIF input multiplexer, low-jitter clock recovery, and flexible serial digital output ports. It operates with +3.3 V analog/digital supplies (VA/VD) and a +3.3 V or +5.0 V logic supply (VL). Packaged in a 28-QFN (5x5 mm) surface-mount case, it functions within a commercial temperature range of -10°C to +70°C.

Audio Special Purpose Procurement Notes

This component is officially listed as Discontinued (EOL). Designers must verify availability through authorized distributors or secondary markets. Confirm compliance with RoHS3 specifications and check for any Product Change Notices (PCN) regarding labeling or manufacturing site updates prior to procurement.

Audio Special Purpose Selection Notes

Select this component for applications requiring high-resolution digital audio reception up to 192 kHz. Ensure the system design accommodates the specific power supply requirements: +3.3 V for VA and VD, and either +3.3 V or +5.0 V for VL. Verify that the control interface (SPI or I²C) aligns with the host microcontroller capabilities. Consider the commercial temperature grade (-10°C to +70°C) against environmental operating conditions.
