CDB42L73

The CDB42L73 board is a dedicated platform for testing and evaluating the CS42L73, an ultralow power mobile audio and telephony CODEC. To allow comprehensive testing of CS42L73 features and performance, extensive hardware and software configurable options are available on the CDB42L73. Hardware options, such as power-supply settings, are configured via jumpers on the stake headers. Software options, such as registry settings for the CS42L73, are configured with the FlexGUI software, which communicates with the CDB42L73 via USB from a Windows compatible computer. In addition, digital I/O headers on the CDB42L73 allow external control signals (for example, an external DSP or microcontroller) to configure and interface with the CS42L73 and other devices directly without the use of FlexGUI. The CDB42L73 also serves as a good component and layout reference for the CS42L73.
