Cirrus Logic Inc. has introduced the CS8422, a 24bit, 192kHz digital audio receiver with a low-jitter PLL and integrated asynchronous sample rate converter.

The digital audio receiver utilizes a high performance PLL, which does not require any external loop filter components, for ultralow jitter clock recovery and high jitter rejection from incoming audio streams. The CS8422 integrates an input multiplexer that supports up to four S/PDIF or two differential AES3 audio inputs, receiver to transmitter pass-through and TDM mode for automotive applications.

The CS8422 is offered in a 32-lead QFN package and operates from a single, 3.3V supply with on-chip level shifters to support a direct interface to logic levels from 1.8V to 5V. Audio data is input through the digital interface receiver or a three-wire serial audio input port, with audio output through one of two three-wire serial output ports. Its phase-lock loop core provides high tolerance to input jitter, and can output 192Fs, 384Fs, 512Fs, 768Fs, or 1024Fs recovered output clock rates.

Price is $3.84 in quantities of 10,000.
