CS8415A
96 kHz Digital Audio Interface Receiver
Features

Complete
General Description
The CS8415A is a monolithic CMOS device which re-
ceives and decodes one of 7 channels of audio data
according to the IEC60958, S/PDIF, EIAJ CP1201, or
AES3. The CS8415A has a serial digital audio output
port and comprehensive control ability through a 4-wire
microcontroller port. Channel status and user data are
assembled in block sized buffers, making read access
easy.
A low jitter clock recovery mechanism yields a very
clean recovered clock from the incoming AES3 stream.
Stand-alone operation allows systems with no micro-
controller to operate the CS8415A with dedicated output
pins for channel status data.
Target applications include A/V receivers, CD-R, DVD
receivers, multimedia speakers, digital mixing consoles,
effects processors, set-top boxes, and computer and
automotive audio systems.
