We want to use LTC6951 as clock for JESD204B and want to interface it with ARRIA 10 FPGA and AD9690
We have two queries:-
1) Whether we can interface SYSREF CML outputs of LTC6951 directly with regular LVDS IOs of ARRIA 10. I am bothered about maximum differential
output of 1600mV whether it can be given to ARRIA 10 or whether it will damage the SOC.
2) Is it essential to power LTC6951 with LDOs or whether the same can be done using DC to DC Converters of ENPIRION used to power the rest of the circuit
including SOC. Like AD9690 has clear instruction of using LDO whereas the none exists for LTC6951. However, we find that EVMs are consistently using
