The CS8405A is a monolithic CMOS device that encodes and transmits audio data according to the AES3, IEC-60958, S/PDIF, or EIAJ CP1201 standards. The CS8405A accepts audio and digital data, which it then multiplexes, encodes, and drives 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 (serial peripheral interface) or 2-wire 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 audio/video receivers, CD-R, DVD receivers, digital mixing consoles, effects processors, set-top boxes, computers, and automotive audio systems.


  • Complete EIAJ CP1201, IEC-60958, AES3, and S/PDIF transmitter; compatible with standards
  • On-chip channel status and user bit buffer memories allowing 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 (cyclical redundancy check) codes and parity bits
  • Standalone mode does not require a microcontroller
  • 5 V digital supply (VD)
  • 3 V to 5 V digital interface (VL)
  • Package: 28-pin SOIC, 28-pin TSSOP; option for lead-free assembly
