The X6-1000M integrates high-speed digitizing and signal generation with signal processing on a PMC/XMC IO module for demanding DSP applications. The tight coupling of the digitizing to the Virtex6 FPGA core realizes architectures for SDR, RADAR, and LIDAR front end sensor digitizing and processing. The PCI Express system interface sustains transfer rates over 2 GB/s for data recording and integration as part of a high performance realtime system.The X6-1000M features two, 12-bit 1 GSPS A/Ds and two 1 GSPS 16-bit DACs. Analog input bandwidth of over 2 GHz supports wideband applications and undersampling. The DACs have features for interpolation and coarse mixing for upconversion. The sample clock is from either a low-jitter PLL or external input. Multiple cards can be synchronized for sampling and down-conversion.A Xilinx Virtex6 SX315T (LX240T and SX475T options) with 4 banks of 1GB DRAM provide a very high performance DSP core with over 2000 MACs (SX315T
