Pentek has today announced the Onyx Model 71791 XMC module. The board is an L-Band RF tuner with two 500 MHz A/Ds based on the high density Xilinx Virtex-7 FPGA. The Model 71791 is designed for connection directly to SATCOM or communications system L-band signals. A front panel SSMC connector accepts L-Band signals between 925 MHz and 2175 MHz, typically from an L-Band antenna or an LNB (low noise block). With its programmable LNA, the Maxim MAX2121 tuner directly converts these L-Band signals to IF or baseband using a broadband I/Q analog downconverter followed by 123 MHz low pass anti-aliasing filters.

The two analog tuner outputs are digitized by two Texas Instruments ADS5463 500 MHz 12-bit A/D converters to capture the full 123 MHz bandwidth, three times that of Pentek's previous L-Band tuners. The Model 71791 features two Acquisition IP modules to easily capture and move data. Each module can receive data from either of the two A/Ds or a test signal generator. Architectural enhancements in the Onyx family include 4 Gbytes of 1600 MHz DDR3 memory and a Gen 3 PCIe interface, delivering peak transfer rates up to 8 Gbytes/s.

The Pentek GateFlow FPGA design kit gives users access to the complete factory installed IP at the source code level. Pentek's GateXpress PCIe configuration manager supports dynamic FPGA reconfiguration through software commands as part of the runtime application. This provides an efficient way to quickly reload the FPGA to slash development time. The Cobalt Model 71791 XMC is designed for commercial, rugged or conduction cooled operating environments. It is also available in several form factors, including 3U and 6U VPX, 3U and 6U cPCI; AMC and PCIe. The Model 71791 XMC module with 4 Gbytes of memory starts at $16,995. Additional FPGA, A/D and LVDS FPGA I/O options are available.
