Digital Audio Interfaces

Select the various digital audio interfaces on the TAS2770EVM Reference Board through hardware
settings and software settings. Several headers on PPC3-EVM-MB allow access to the following digital
audio signals:

•

I2S Data out (SDOUT) from the TAS2564 (for example, current and voltage sense data)

•

I2S Data in (SDIN) to the TAS2564

•

I2S Word clock or frame sync (FSYNC)

•

I2S Bit clock (SBCLK)
