Compressed data can be delivered in IEC61937 format via the S/PDIF port and in bursty mode via the PC interface. PCM data can be accepted through the digital input connectors or from the on-board ADC. Six chan- nels of audio are provided on the six analog outputs and on three optical S/PDIF transmitters. CLKIN for the DSP can be derived either from the on-board oscillator or the external PLL. MCLK can be extracted from incoming S/PDIF streams, generated with the external PLL, or mastered by the audio decoder. The CDB4923/300 incorporates a Crystal Multichannel Audio Decoder, the CS4340 24-Bit Audio D/A Converter, the CS8414 Digital Audio Interface Receiver, the CS8404A Digital Audio Interface Transmitter, and the CS5334 20-Bit Stereo A/D Converter.
