I'm trying to use 4 JESD lanes to capture baseband DDC IQ data at (decimate x4) 614.4MHz with a sample clock of 2457.6 MHz using the ADC32RF45evm board.
To make this sort of work, I load up the clock file LMK_ADC32RF45_lmfs82820_2457p6_MSPS.cfg and my own custom setup file that sets the decimation to 4 and the NCO frequency to 780 MHz (My input signal is a 500MHz wide set of tones centered at 780 MHz).
The final trick was to use the ADC32RF80_LMF_8221 configuration in HSDCP. Unfortunately this is using 8 lanes at 6.14Gb/s and I want to use 4 lanes at 12.28 Gb/s. Are there more config files for HSDCP somewhere that will allow me to do this? I also assume that I will need to do some JESD configuration in the ADC32RFxx EVM to set this up as well, so any insights there would be helpful also.
