Multi-Gsps, Multi-board Analog IO Synchronization
April 10, 2018Download PDF
Some problems can be difficult to solve. Phase accurate synchronization of analog signals through multiple analog to digital converters at multi-GHz rates on a single card is one such problem. Synchronization between multi-boards or systems raises the bar even further. To do this over wide temperature ranges reliably takes the problem up yet another notch.
The challenge was to achieve all of these with eight Curtiss-Wright’s VPX3-530 transceivers; each with four 2 Gsps data converters, a total of 32 analog input channels requiring cycle accurate synchronization. The VPX3-530 has also dual analog outputs for a total of 16 analog output, all demanding synchronization.
