TAS5711: MCLK

datasheet said: The clock section uses MCLK or the internal oscillator clock (when MCLK is unstable, out of range, or absent) to produce the internal clock (DCLK) running at 512 time the PWM switching frequency.

so it means we can use Serial Control Interface Operational Without MCLK?

How can we use the internal oscillator？

We don't have ADC or MCU in the system, juse I2S input from CSR8670, and we use extenal cystal to creat a clock for TAS5711, but seems can't work well.

Hope you can give us suggestions., thanks.
