... CDB4352 SYSTEM OVERVIEW The CDB4352 evaluation board is an excellent means of quickly evaluating the CS4352. The CS8416 digital audio interface receiver provides an easy interface to digital audio signal sources including the majority of digital audio test equipment. The evaluation board also allows the user to supply external PCM clocks and data through a header for system development ...

... CS4352 as possible. Extensive use of ground plane fill in the evaluation board yields large reductions in radiated noise. 7. HARDWARE CONTROL The CDB4352 is controlled through settings on switch S1. This allows for configuration of the board without a PC. A switch is provided for CS8416 MCLK speed, clock and data source for the board, and the hardware mode config- uration of the CS4352. ...
