CS8416K-CZZR

Audio Special Purpose Overview

The CS8416K-CZZR is a monolithic CMOS digital audio receiver manufactured by Cirrus Logic Inc. It decodes one of eight stereo pairs of digital audio data according to IEC60958, S/PDIF, EIAJ CP1201, or AES3 interface standards. The device features an 8:2 S/PDIF input multiplexer and supports sample frequencies from 32 kHz to 192 kHz. It operates with a +3.3 V analog supply (VA), a +3.3 V digital supply (VD), and a +3.3 V or +5.0 V digital interface supply (VL). The component is housed in a 28-TSSOP package and functions as an audio receiver for digital audio interfacing applications.

Audio Special Purpose Procurement Notes

This part number is listed as Obsolete/End-of-Life (EOL) by distributors such as DigiKey. Availability is limited to stock or third-party sources. The 'K' suffix typically denotes the commercial temperature grade (-10°C to +70°C), while the non-K version may denote automotive grade (-40°C to +85°C); verify specific lot markings against manufacturer PCNs if critical.

Audio Special Purpose Selection Notes

Select this component for systems requiring decoding of up to eight stereo pairs of digital audio streams. Ensure the design accommodates the required power supplies: VA and VD at +3.3 V, and VL selectable between +3.3 V and +5.0 V. Verify that the host system can interface via SPI or I²C for register configuration in software mode.
