Hi,
We have Two LMX2594 devices, used to generate ADC Device clocks to the x3 ADC12DJ5200 IC (refer below image).OSCIN for LMX2594 Device is generating from LMK48032 PLLoutput. As we need Multichannel ADC synchronization, all lmx device outputs should be phase synchronized.
In this case we are not using SYSREF (sysref dividers) from the LMX2594 Device (Refer LMX2594 GUI Image).
- If sysref path is not used, do we need to use sysrefreq signal?
- As we are using same RFOutA and RFOutB output frquencies from LMX2594, do we need to manually synchronize both RFOutA and RFOutB output channels using sysrefreq pin? If yes, then can I generate sysrefreq signal from FPGA? otherwise should I leave sysrefreq signal open or does this signal will use to achieve multi device synchronization?
Please help
