Tool/software:
Hello, I am attempting to synchronize multiple ADC3644 and would like to know how and what signal to feed into the PDN/SYNC pins for complex decimation. I assume I must first configure it using SPI, then generate a square waveform (buffered and matched trace lengths) into the pins, is this correct? Furthermore, does the frequency of the sync signal matter in reference to the clock/sample clock, or does any integer multiple of 64Hz work, or any frequency in general? Thank you.
