I am debuging new design with TAS5707 + ARM M4 + MEMS microphone.
I cannot get any sound from TAS5707.
I am running on fs=16kHz, BCLK=768kHz MCLK=6,144MHz
I am using MCU crystal which is 8MHz so the master clock is generated internaly by dividing and droping cpu clocks - so there is some jitter.
How much is TAS5707 tollerant to MCLK jitter?
When I read register 0x00 I get 0b10010000 so I suppose that TAS5707 detect my setup Fs=16kHz and MCLK =384xFs correctly
Then when I read error status register I get autolock error bit . What this bit means?
My design is based on TI EVM module schematic.
When I scope MCLK it looks little "nervous". When I scope audio power outputs there is zero signal.
