General Description
The CS8416 is a monolithic CMOS device which re-
ceives and decodes one of 8 channels of audio data
according to the IEC60958, S/PDIF, EIAJ CP1201, or
AES3 interface standards. The CS8416 has a serial dig-
ital audio output port and comprehensive control ability
through a selectable control port in Software Mode or
through selectable pins in Hardware Mode. Channel sta-
tus data are assembled in buffers, making read access
easy.
GPO pins may be assigned to route a variety of signals
to output pins
A low jitter clock recovery mechanism yields a very clean
recovered clock from the incoming AES3 stream.
Stand-alone operation allows systems with no microcon-
troller to operate the CS8416 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 au-
tomotive audio systems.
