SDR receiver VPX board

13 October 2010 Computer/Embedded Technology

Pentek’s Model 5331 is a general-purpose, 16-channel multiband digital receiver 3U VPX board. It includes both a Virtex-II FPGA and two 14-bit A/Ds for signal processing and features built-in support for PCI Express (PCIe) Gen. 2 over the 3U VPX backplane.

The board accepts two analog RF inputs at +4 dBm full scale into 50 Ω on front panel SMA connectors. The two inputs are transformer coupled and digitised by AD6645 14-bit A/D converters which operate at a maximum sampling rate of 80 MHz in the standard unit and up to 105 MHz for option -100. The 5331 includes four TI/Graychip GC4016 quad multiband digital down-converter chips. The maximum input sampling rate for the GC4016 is 100 MHz. Each device includes four independently tuneable channels capable of centre frequency tuning from DC to ƒS/2, where ƒS is the sample clock frequency.

With a 100 MHz sample clock, the useable output bandwidth of each of the down-converter channels is 2,5 MHz. However, since the Model 5331 delivers parallel digital outputs from the GC4016 into the FPGA, users can take advantage of the GC4016 channel combining mode to join two or four channels into a single channel with a resulting bandwidth of 5 or 10 MHz, respectively. This supports many of the new wideband wireless standards. Since both A/D converters connect directly to the FPGAs, signals with even wider bandwidths can be accommodated.
