Single-Slot VXS Module Streams 12-Bit Data At 1 Gsamples/s

In a single 6U VME/VXS slot, the QuiXilica Atlas-V5 VXS provides up to eight channels of 12-bit, 1-gsample/s analog inputs streaming up to 12 Gbytes/s into three Xilinx Virtex 5 FPGAs. Each channel has an input bandwidth of 1.5 GHz, which supports operation up to the third Nyquist band, and uses a single ADC without interleaving. The front-end FPGAs, typically SX95T devices, each accept four channels of input data for initial processing. The outputs of the front-end FPGAs (up to 6 Gbytes/s each) are then combined in the back-end FPGA for additional processing and output via the VXS backplane or front panel QSFP fiber-optic links at aggregate rates up to 3.75 Gbytes/s. When configured with an SX240T back-end FPGA, the Atlas-V5 delivers 2336 V5 DSP slices with up to 1.3 TeraMACs/s of signal processing capability. The Atlas-V5 includes hardware support for sample-accurate synchronization both within a single card and across multiple cards, allowing the module to support high-channel-count applications such as beamforming and interferometry with up to 144 channels in a single VXS chassis.
