CS8405A 96 kHz Digital Audio Interface Transmitter Features Complete EIAJ CP1201, IEC-60958, AES3, S/PDIF-compatible Transmitter V Digital Supply VD+ V or V Digital Interface VL+ On-chip channel status and user bit buffer memories allow block-sized updates. Flexible 3-wire Serial Digital Audio Input Port Up to 96 kHz Frame Rate Microcontroller Write Access to Channel Status and User Bit Data On-chip Differential Line Driver Generates CRC Codes and Parity Bits Standalone Mode Allows use Without a Microcontroller The CS8405A is a monolithic CMOS device which encodes and transmits audio data according to the AES3, IEC60958, S/PDIF, or EIAJ CP1201. The CS8405A accepts audio and digital data, which is then multiplexed, encoded, and driven onto a cable. The audio data is input through a configurable, 3-wire input port. The channel status and user bit data are input through an SPI or microcontroller port, and may be assembled in block-sized buffers. For systems with no microcontroller, a standalone mode allows direct access to channel status and user bit data pins. Target applications include A/V Receivers, CD-R, DVD receivers, digital mixing consoles, effects processors, set-top boxes, and computer or automotive audio systems.
