I am wondering about how to connect the MCLKIN line in a circuit for the ADAU1977.
I am planning to drive the chip in slave mode.
In the data sheet reference design for the ADAU1977 (page 65), it suggests the PLL_FILT to be setup using LRCLK values :
But my question is, where should I connect MCLKIN ?
Currently I assume that the PLL is not being used and I connect MCLKIN (pin 7) to GND.
Will that work ?
Is there a better place to connect it ?
