96 kHz, Digital Audio Transceiver

The CS8427 is a stereo, digital audio transceiver with AES3 and serial, digital audio inputs, AES3 and serial digital audio outputs, along with comprehensive control through a 4-wire micro-controller port. Channel Status and User data are assembled in block-sized buffers, making read/modify/write cycles easy.

A low jitter, clock recovery mechanism yields a very clean recovered clock from the incoming AES3 stream.

Target applications include A/V receivers, CD-R, DVD receivers, multimedia speakers, digital mixing consoles, effects processors, set-top boxes, computer, and automotive audio systems.
