Engineers designing modern SDR applications know there are many trade-offs between options, including PMC/XMC versus VXS. As newer FPGA technology is developed and deployed, however, VXS will be better able to satisfy growing requirements for more board and front-panel space, higher densities, more IP core and I/O choices, and improved analog performance than PMCs or XMCs.
