CDB4265

The CDB4265 evaluation board is an excellent means for evaluating the CS4265 CODEC. Evaluation requires an analog/digital signal source and analyzer, and power supplies. A Windows PC compatible computer must be used to evaluate the CS4265.System timing for the I²S, Left-Justified and Right-Justified interface formats can be provided by the CS4265, the CS8416, or by a PCM I/O stake header with an external source connected. RCA phono jacks are provided for the CS4265 analog inputs and outputs. Digital data I/O is available via RCA phono or optical connectors to the CS8416 and CS4265.The Windows software provides a GUI to make configuration of the CDB4265 easy. The software communicates through the PC’s serial port to configurethe control port registers so that all features of the CS4265 can be evaluated. The evaluation board may also be configured to accept external timing and data signals for operation in a user application during system development.
