Other Parts Discussed in Thread: TAS5760M
Hi,
I am currently trying to use the TAS5760L(PBTL mode) to play some audio from a ucontroller, but there is no signal coming out of it when checking with a scope.
1.I am a bit unsure about if the required clock rates from the I2S is supportable, my MCK is set to be 2.9 MHz(64*fs) with a LRCK of 44100 Hz and SCK of 1.41 MHz. I didn't quite understand the given table on the datasheet for the supported SCLK rates, could you validate the clocks?
2. If they arent valid, is there anything that could be done whether to check if there is other DAC's/amplifiers that could support these rates.
3. On the analog control register, how do I decide which OUTPUT switching rate I should have, I just set it to the default value 16*LRCK.
4.Also what is the channel selection for PBTL mode(analog control register), aren't both of the channels connected to the output filter?
Below I have analyzed my I2S, I2C bus and the SPK_SHUTDOWN* pin:
