Audio Interfaces (J301/J302/J303)

Quectel M.2 EVB provides one digital audio codec board interface (PCM) J301 and two analog audio
interfaces J302 and J303. This chapter gives a detailed introduction on these audio interfaces.

4.4.1.

Digital Audio Codec Board Interface (J301)

The M.2 EVB supports the external digital audio codec of TLV320AIC3104. The codec circuit is assembled

on an independent small board which can be interconnected with EVB by the BTB connector J301.

The following figures show a reference design for the connection between digital audio codec board and

the EVB.
