Board Overview The FMC_XM134 is a 4-channel 3.2 GSPS (or configurable to 2-channel 6.4 GSPS) 12-bit ADC acquisition FMC+ daughter card module. This board adheres to the FMC+ standard and complies with the VITA57.4 specification. It can be coupled as an ideal I/O module to the FPGA front-end. After digitization, RF analog signals are transmitted to the FPGA via a 16-lane JESD204B interface. The board supports a maximum of 2 channels of 6.4 GSPS RF direct sampling, with a -3dB analog input bandwidth of up to 8 GHz. Signals with instantaneous bandwidths below 3 GHz can all be digitized within the first Nyquist zone.

The board supports an on-board programmable sampling clock and an external reference clock. Multiple boards can also perform synchronized acquisition via trigger (input/output) signals. The board's 4 analog signal inputs are connected via 50Ω characteristic impedance SSMC RF connectors, using AC transformer coupling. The board can be widely used in radar signal processing, electronic warfare, and other applications.
