CS8416
192 kHz Digital Audio Interface Receiver
Features
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
Complete EIAJ CP1201, IEC-60958, AES3,
S/PDIF compatible receiver
+3.3V Analog Supply (VA)
+3.3V Digital Supply (VD)
+3.3V or +5.0V Digital Interface Supply (VL)
8:2 S/PDIF Input MUX
AES/SPDIF input pins selectable in hardware
mode
3 General Purpose Outputs (GPO) allow signal
routing
Selectable signal routing to GPO pins
S/PDIF to TX inputs selectable in hardware mode
Flexible 3-wire serial digital output port
32 kHz to 192 kHz sample frequency range
Low jitter clock recovery
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.
Pin and microcontroller read access to Channel
Status and User data
SPI or I²C control port Software Mode and
standalone Hardware Mode
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.
