6.4.1 PurePath™ Console 3 Software

The TAS2120's advanced features and device configuration can be performed using PurePath Console 3(PPC3) software. The base software PPC3 is downloaded and installed from the TI website. Once installed the TAS2120 application can be downloaded from with-in PPC3. The PCC3 tool calculates necessary register coefficients that are described in the following sections. The device performance is optimized using registers named TUNING based on the options for system configuration selected in the GUI. This is the recommended method to configure the device. Once the TAS2120 application calculates and updates the device, the registers values can be read back using the PPC3 tool for final system integration.
