We had a project that works on the EVB (from Analog) ,
the input is the ADC it than goes (after some filttering) to 3 I2S outputs at 192K at master mode.
we made 10 boards prototype, only 2 boards are working , all the other have no BCLK out of the ADAu1701 (and all other clocks as well)
all voltages are correct, input clock , PLL_mode are same .
What can cause such a problem ?
can decupling can cause it ?
