HOUSTON, 15 Jan. 2007. VMETRO in Houston announced the PMC-FPGA05-ADC1, a Xilinx, Inc. Virtex-5 LX110 FPGA based PMC module with integrated dual analog input channels.

By closely coupling the high-performance FPGA processing and the analog I/O, the PMC-FPGA05-ADC1 is for applications requiring maximum performance with minimal latencies such as Software Defined Radio (SDR), Signal Intelligence (SigInt) and data recording.

The analog input front end incorporates dual channel analog input with a full power input bandwidth of between 100 kHz and 110 MHz with a signal to noise ratio (SNR) of 68dB and a spurious free dynamic range (SFDR) of 82dB.

The PMC-FPGA05-ADC1's dual analog interfaces combined with the processing power and PCI-X bus interface enable this PMC module to provide front-end processing.

Processing on the PMC-FPGA05-ADC1 is provided by a Xilinx XC5VLX110 Virtex-5 FPGA. Supported by three banks of QDRII SRAM (8 megabytes per bank) and two banks of DDR2 SDRAM (128 megabytes per banks), the Virtex-5 FPGA is capable of performing sophisticated, high-speed DSP tasks in a small footprint. The PMC module supports a 133 MHz PCI-X interface as well as PMC digital user I/O via the Pn4 connector. Both of these interfaces are provided by the FPGA.

Software support for the PMC-FPGA05-ADC1 includes host drivers for Windows and VxWorks. Linux support is scheduled for the second half of 2007. The drivers support high-speed DMA to minimize potential bottlenecks between the analog input, the FPGA and the host processor. Utilities and example VHDL are provided to support customers' development of FPGA firmware as well as providing diagnostic support.
