DAC3482 Sync
One MM CTM are using the DAC3482
We want to get the fixed delay(latency) value from DAC3482 input to output from power-on to power-on.
We reference the 3482 datasheet and the slaa584 that DAC348x Device Configuration and Synchroniztion, DAC3482 Device Logics Synchronizatioan Sources as follows the table 1.

The QMC is not used.
DATACLK =100MHz, DACCLK = 800MHz,interp = 8x,
SYNC and FRAME are from DATACLK by dividing 16 are 6.25MHz,and they are periodic signal.
The Refence Clk is 100MHz, N=1;M=8,P=5,VCO = 4000MHz
OSTR = PFD = 100MHz.
We start sequence is recommended to power-up the DAC3482 according to the datasheet in page-73.
We found the delay is variational from power-on to power-on.
Can you tell me the question about our configuration.
