1/20/2004 - Pentek, Inc., the industry pioneer of VME board-level technology, launched a new single-channel, 6U VMEbus board featuring one of the fastest 12-bit analog-to-digital (A/D) converters in the market with sampling rates to 210 MHz. Targeting extremely high-performance DSP tasks, the Pentek Model 6821 couples this high-speed A/D to two new Virtex-II Pro FPGAs by Xilinx. The board excels in acquisition, demodulation, convolution, filtering, processing, and analyzing operations critical for many real-time, high frequency applications.
The Model 6821 accepts one front-panel analog input and delivers digital output samples over two or four front panel data port (FPDP or FPDP II) connectors. A front panel low-voltage differential signaling (LVDS) bus supports synchronous, triggered data acquisition across multiple boards. This capability is essential for multi-channel applications such as radar and direction finding.
Rodger Hosking, vice president of Pentek, Inc. explained, "With the new Analog Devices AD9430 A/D connected directly into both Virtex-II Pro FPGAs on a single board, Model 6821 customers can now digitize a 100 MHz bandwidth signal andprocess it in real time!" He went on to say, "Our new 6821 can be used as a stand alone system or as a powerful front-end preprocessor for Motorola G4 PowerPC and Texas Instruments C6000 DSP boards. Four FPDP ports deliver tremendous throughput to a wide range of third-party products, while two 128 MB local memories handle real-time buffering for tracking, transient capture and recording applications."
Flexible Design with Robust I/O Features
The Virtex-II Pro FPGAs represent the latest FPGA offering from Xilinx. The 6821 features two XC2VP20 or XC2VP50 devices, each with up to 6 million system gates and as many as 232 hardware multipliers. These multipliers along with generous on-chip configurable RAM make these FPGAs ideal for handing real-time DSP algorithms at the 210 MHz A/D sampling rate.
The two FPGAs are optionally equipped with 128 MB of SDRAM for data delay and buffering capacities, critical for many real time applications where a digital delay is essential such as radar and signal intelligence. Two 16 MB flash memories support boot operations for optional use of the embedded FPGA microcontrollers.
The A/D converter sample clock can be sourced from an internal crystal oscillator or from an externally supplied sinusoidal clock at a maximum frequency of 210 MHz. This clock is accepted through a front panel SMA connector terminated in 50 ohms.
Four FPDP output ports, two for each FPGA, support data transfer rates of 320 MB/sec each. One port per FPGA is located on the 6821 front panel, while the second is available on an optional second-slot panel. Additional LVDS data I/O is available through either the VMEbus P2 connector or the optional second-slot front panel.
FPGA Development Resources
Pentek's GateFlow FPGA Resources include the GateFlow FPGA Design Kit supporting user-defined FPGA algorithms; the GateFlow IP Core Library for high-performance FFTs (Fast Fourier Transform), digital receivers and radar pulse compression algorithms; and GateFlow Factory Installed IP Cores so customers can take immediate advantage of FPGA technology with zero FPGA development effort.
