Vmetro has announced a high-speed analogue input XMC module with the high speed I/O performance of the Virtex-5 FPGA.

The AD1520 is a dual channel 1.5Gsample/s ADC XMC/PMC module. A National Semiconductor ADC08D1520 8-bit converter on the analogue input is connected to either a Virtex-5 SX95T, LX110T or LX155T FPGA back-end. The aim to is provide wideband analogue input and high-end FPGA processing for demanding real-time applications such as radar and telecommunications.

The board, which is the next generation model of the ADC1500, shows typical performance characteristics of 7.4 ENOB, 61dBc SFDR and 47 db SNR at 373 MHz. The full power input bandwidth extends to beyond 2GHz.
It has LVPECL trigger input and output connections along with sample clock input and general purpose I/Os on the front panel. This allows it to be operated in a range of modes, including multi-board synchronous sampling.

There is also a clock generator PMC/XMC card, which can be used to generate low skew, minimal jitter clock signals to the ADC boards and coordinate multi-board synchronisation.

The FPGA is connected to two 9Mbyte memory banks of high bandwidth QDRII SRAM capable of accepting the incoming data at full speed from the ADC and two 128Mbyte banks of DDR2 SDRAM.

The module is supported by a development kit, the FusionXF which includes a software development kit which provides host software support for Windows, VxWorks and Linux, including drivers for high-speed DMA access between the XMC and host CPU, FPGA reconfiguration and diagnostics. A hardware kit contains the FPGA interface definitions and HDL functions to build a fully functional FPGA design.
