CS8416K-CNZ

Audio Special Purpose Overview

The CS8416K-CNZ 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 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). It supports sample frequencies ranging from 32 kHz to 192 kHz and features low-jitter clock recovery mechanisms. The component is housed in a 28-QFN package.
