Hi there,

i have a custom board with AD1938 with connection to a ADAU1442 board.

MCLKI is connected to CLKOUT with 12.288MHz at ADAU1442.

What are the Register Settings on AD1938 to run the ADC and DAC at 192kHz in slave mode from 12.288MHz from MCLKI?

In DAC Control Register 0[2:1] 10 = 128 kHz/176.4 kHz/192 kHz, ok but what i have to do to select 192kHz?

In DAC Control Register 1[6] 1 = internaly generated, means from PLL in slave mode?

 

Thanks for your help.

 

Greetings, 

Hans
