Audio pins configuration

SANGILI KUMAR

Hello

We are designing Android custom device with Audio, GSM, Bluetooth audio, and FM these four peripherals have audio signal. How can i design schematic for these audio pins communicating with my AM335x chip.

In AM335xevm_sk kit schematic just two kind of audio signals implemented Bluetooth audio and AUDIO IC signal additional we have FM and GSM audio.

Advice me how can i design ?

Thanks in advance.

How can you expect to receive help when only you know what interfaces your peripherals have? The AM335X has two McASP peripherals, each with up to four channels. You should read section 22 of the AM335X Technical Reference Manual.

Hello Biser

Ya i know. But in AM335xevm NAND,NOR,MMC,WiFi etc, everything is configure with CPLD to compromise the pin conflict issues.

Likewise Is there any solution like use external chip to mange these audio signals? Because we need to implement AUDIO IC, GSM audio signal and FM audio signal.

First of all you should consider whether you have enough McASP pins available on the AM335X for all these devices. Then you should check the audio formats/bit rates required, and whether they can be supported by the McASP hardware.
