Overview

The X6-RX is a flexible IF receiver that integrates IF digitizing with signal processing on a PMC IO module. The module provides up to 48 configurable receiver channels with a powerful Xilinx Virtex 6 FPGA signal processing core, and high performance PCI Express/PCI host interface. With the X6-RX, IF recorders can log both the digitized raw data and channels real-time sustaining rates over 1 GB/s.

The X6-RX features four, 16-bit 160 MSPS A/Ds with dual digital downconverters (DDC). IF frequencies of up to 300 MHz are supported. The sample clock is from either a low-jitter PLL or external input. Multiple cards can be synchronized for sampling and downconversion.

A Xilinx Virtex6 SX315T (LX240T at initial release) with 4 banks of 128MB DRAM provide a very high performance DSP core with over 2000 MACs (SX315T). The close integration of the analog IO, memory and host interface with the FPGA enables real-time signal processing at extremely high rates.

Dual TI/GrayChip DDCs, connected directly to the FPGA, provide up to 48 narrowband or 8 wideband channels, with input from any A/D channel. The DDC perform complex or real downconversion, with flexible controls for mixing, filtering, decimation, output formats and data rates. Channels can be synchronized to support beam forming or frequency hopped systems.

The X6 family power is less than 15W for typical operation. VITA 20 conduction cooling is used with a heat-spreader and sink are Ruggedization levels for wide-temperature operation and conformal coating are supported.

The FPGA logic can be fully customized using VHDL and MATLAB using the Frame Work Logic toolset. The MATLAB BSP supports real-time hardware-inthe-loop development using the graphical, block diagram Simulink environment with Xilinx System Generator. IP cores for DDC, demodulation, and FFT are available.

Software tools for host development include C++ libraries and drivers for Windows and Linux. Application examples demonstrating the module features and use are provided.

This extremely versatile module is easily adapted for use in virtually any type of system. Our XMC carrier adapters offer conduction and convection cooling and are available for a range of interfaces including Desktop PCI, Desktop PCI Express, Cabled PCI Express, CompactPCI, and PXI/PXI Express. This module is also readily installed into Innovative Integration's eInstrument Embedded PC, SBC-ComEx Single-Board Computer, and Andale Data Loggers.
