Cirrus Logic CDB43198K Evaluation Kit is a dedicated platform for testing and evaluating the CS43198 high-performance DACs. This evaluation kit consists of an evaluation board, a USB cable, and a High Dynamic Range (HDR) measurement board (CDB-HDR-MEAS). The CDB43198 board directs the clock from the digital input sources to/from the CS43198 UTs by utilizing five buffers with direction control. This evaluation board uses the J42 pin that provides an I2C interface to connect a host adapter to support communication with a smart codec. The smart codec helps perform listening tests with various equalizer filters based on the impedance of the attached headphone.
