Overview

The CS8422-CNZ is a 24-bit, high performance, stereo asynchronous sample-rate converter with an integrated digital audio interface receiver that supports AES3 and S/PDIF interface standards. This integrated feature set removes the requirement for system platforms to vary system clocking when integrating asynchronous digital interfaces. Audio data is input through the digital interface receiver or a 3-wire serial audio input port. Audio is output through one of two 3-wire serial audio output ports. Serial audio data outputs can be set to 24, 20, 18, or 16-bit word lengths. Data in the digital interface receiver and serial audio input port can be up to 24-bits long. Input and output data can be completely asynchronous, synchronous to an external clock through XTI, or synchronous to the recovered master clock. The CS84222 can be controlled through the control port in Software Mode or in a Stand-Alone Hardware Mode. In Software Mode, the user can control the device through an SPI or I²C control port. The CS8422-CNZ is ideal for consumer, professional and automotive applications such as audio/video receivers & HTiB, digital mixing consoles, digital effects processors and automotive amplifiers.
