UPPER SADDLE RIVER, N.J., 10 Sept. 2009. Pentek Inc. in Upper Saddle River, N.J., is introducing the Model 7158 data converter PMC card/XMC transceiver module for high-speed, wideband and electronic warfare applications such as remote radar countermeasures, tracking, and UAV surveillance.
The Model 7158 is a dual-channel, 12-bit 500 MHz data converter that builds on the Pentek Model 7156 by extending the A/D sampling rate. By coupling the high speed analog I/O data converters through powerful FPGA resources, this signal processing module can receive a signal, process it, and send it back out in real time.
This module is also available as a PCI board, Model 7658; as a 3U and 6U CompactPCI module, Model 7258 and 7358 respectively; and as a PCI Express module full- and half-length versions with the Models 7758 and 7858.
"The dual, on-board Virtex-5 FPGAs add a wealth of DSP resources and are a perfect match to these higher-rate A/Ds to handle real-time signal processing," says Rodger Hosking, vice president of Pentek. The 7158 high-speed transceiver is suited for rugged systems deployed and lab environments.
The signal processing FPGA of the 7158 handles the real-time DSP algorithms while the second FPGA provides a status and control path to the PC or carrier board. Additionally, the FPGA can be a Xilinx FXT family device with a PowerPC processor, forming a complete, self-contained subsystem. Users can install an Ethernet stack so the module can communicate over gigabit Ethernet to external systems in the vehicle or craft.
Using Pentek's GateFlow FPGA Design Kit, customers can develop and integrate custom IP to support a wide range of real-time applications for communication, signal intelligence, beamforming and radar countermeasures.
Reconfigurable FPGAs Extend Board Functions
A total of 512 megabytes of DDR2 SDRAM memory arranged in two banks enables users to capture real-time data, storing it in a local memory for applications like wideband radar in which the destination device cannot handle the peak real-time data rates, and the SDRAM acts as an elastic buffer.
The SDRAM can also be used to store an arbitrary waveform for playback through the D-A converters. Optionally, the total SDRAM capacity can be doubled to 1 gigabyte.
The 7158 is supported with the ReadyFlow Board Support Package under Windows, Linux and VxWorks operating systems. Each BSP includes an OS driver as well as a have ReadyFlow C language library to support all board functions and provide sample applications for quick development startup.
