Part Number:ADC08D1520
Hello,
My customer has a question about ADC08D1520.
[Background]
They evaluated the output waveform of the ADC08D1520 while changing the sampling clock phase with the registers (Addr=Fh) in their board.
Input signal is CW.
The configuration is 1:4 DEMUX DES MODE.
They changed the phase from 0ps to 142ps with course phase adjust and intermediate phase adjust.
It swapped DI and DId, DQ and DQd in that test.
[Q1]
Is there a possibility that the swapping DI and DId, DQ and DQd occurs by changing the phase adjust ?
[Q2]
Does the DCLK phase change by changing the phase adjust ?
Best Regards,
Hiroshi Katsunaga
