General Description
The CS8427 is a stereo digital audio transceiver with
AES3 and serial digital audio inputs, AES3 and serial
digital audio outputs, and includes comprehensive con-
trol ability through a 4-wire microcontroller port. Channel
status and user data are assembled in block-sized buff-
ers, 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, and computer and au-
tomotive audio systems.
