ADC34J45EVM: Register 0x30 Octets per Frame

Goran Marinkovic
Intellectual 330 points
Part Number: ADC34J45EVM

Tool/software:

The datasheet SBAS664B –MAY 2014–REVISED NOVEMBER 2014 states for the setting "00000000 = 20x serialization: two octets per frame"

However the ADC3000 GUI does the following, it does "ADC34Jxx 0x30[0x30]-[0x1]"

Which one is correct? I assume it's the datasheet.... however the GUI value makes more sense to me. And both work?????!!!!! At least my FPGA is able to lock to the Multi Gigabit Link.

    Hi Goran,

    It is likely that the only bit that matters to decide 20x or 40x serialization is actually bit 1, which would make sense here. I would suggest to use the datasheet values when any discrepancy like this occurs and both work, this is so you can reference the datasheet later on instead of the gui, since the gui has a higher chance of not being updated.

    Thanks, Chase

    Hello Chase,

    I changed my configuration to:

    0x030 0x00           // Register 0x030; bit(7:0) := OCTETS PER FRAME = '00000000' = 20x serialization: two octets per frame

    Cheers
