Other Parts Discussed in Thread: ADC12J4000, ADS54J66, LMK04828
HI,
I have two ADS54J66EVM boards and two TSW14J56 boards. Can I synchronize ADS54J66s on two ADS54J66EVM boards?
I notice that in tidu851 the way of synchronziation of two ADCs(ADC12J4000) is described. But I still have some questions about that:
(1) In tidu851, the chain of "trigger in" on board is TMST+(boardA) ——>R18(boardA)——>SYNC_P(boardA)——>FPGA(master)——>SYNC_N(boardA)——>TMST-(boardA)——>TMST+(boardB)——>R18(boardB)——>SYNC_P(boardB)——>FPGA(slave)——>SYNC_N(boardB)——>TMST-(boardB,named as " Trigger out"). What is "trigger out" for on TMST- of board B?Why is it connected by a SMA cabel? It seems that someone will use this singal?
(2) The "trigger in" is internally connected to FPGA by pin G12 of FMC, which is Net SYNCbABP on board ADS54J66EVM. So if I want to synchronize two ADS54J66s, should I cut the microstip line of net SYNCbABp and SYNCABm,then put coaxial pigtails on them? And then connect all of them as described on tidu851?
(3) I think the firmware will be changed if I use synchronization_2x_demo.exe to synchronize two ADS54J66s instead of two ADC12J4000s. So do you have that firmware based on ADS54J66? If not , do you have other ideas about synchronizing two ADS54J66EVMs based on two TSW54J66EVMs?
Best Regards
