Other Parts Discussed in Thread: TAS5508C, TLV320AIC3206
Hi All,
We are working on a 2.1 channel audio amp with TAS5508C. (It is a long story on why we use an 8-channel controller for 2.1 design.) There are several audio sources: I2S out from LM3S9B96 and an BT module.
LM3S9B96 provides its own master MCLK and I2S data so we are fine here. However, the BT module is a master I2S but it only provides SCK, WS (Word Select) & SD (Serial Data). It doesn't provide any MCLK signal. BTW, the BT module uses 48K hz sample rate.
Here are my questions:
1. Is there any way to interface this BT module directly to TAS5508C?
2. If that is an option, I am thinking to use BT I2S as input to LM3S9B96 and let LM3S9B96 output the audio data to its I2S output port along with MCLK. It seems to be a possible solution but we need to write some code in LM3S9B96. Has anyone had this successfully? Or does anyone have any comment/suggestion?
