3.7. Audio Interfaces (J0801/J0802/J0803)

The EVB provides one digital audio codec board connector (J0803), two analog audio connectors

(J0801/J0802). This chapter gives a detailed introduction on these audio interfaces.

3.7.1. Digital Audio Interface (J0803)

The EVB supports external digital audio codec ALC5686 or SLIC LE9643. The codec or SLIC is

assembled on an independent TE-A which can be connected to the EVB by the BTB connector (J0803).
