Multi-Gsps, Multi-board Analog IO Synchronization

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.

VPX3-530 from Curtiss-Wright - 3U VPX Xilinx Virtex-7 FPGA ADC/DAC

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.

Analog Input Performance of VPX3-530

This white paper provides the typical (measured) performance of the analog inputs of the VPX3-530, what the advantages are of various modes and how well they compare with the formal device datasheets. The white paper then proceeds to give an insight to the true performance of the VPX3-530 in order for the developer to make reasoned decisions as to whether the VPX3-530 will meet application requirements and which configuration would be most effective for a particular application.


Meeting the demands of signal intelligence and electronic warfare with the VPX3-530

With increasingly advanced threats in signal intelligence and electronic warfare, systems need to be reliable and SWaP-optimized. Stay ahead of the game with Curtiss-Wright and the VPX3-530.
