CS8415A
96 kHz Digital Audio Interface Receiver
Features
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.
! Complete EIAJ CP1201, IEC-60958, AES3,
S/PDIF compatible receiver
! +5 V Analog Supply (VA)
! +3 V to +5 V Digital Interface Supply (VL)
! 7:1 S/PDIF Input MUX
! Flexible 3-wire serial digital output port
! 8 kHz to 96 kHz sample frequency range
! Low jitter clock recovery
! Pin and microcontroller read access to
Channel Status and User data
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.
! Microcontroller and standalone modes
! Differential cable receiver
! On-chip Channel Status and User data buffer
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.
