VME board rips through radar acquisition
A new dual-channel 6U VMEbus signal acquisition and processing board boasts sampling rates up to 215MHz.
Pentek has a new dual-channel 6U VMEbus signal acquisition and processing board with sampling rates to 215MHz Featuring some of the fastest 12bit analogue-to-digital (A/D) convertors in the market, the Pentek Model 6822 supports these datarates with several high-speed interface options

DSP board aims for leading edge imaging
Researchers at the University of Washington and IBM are using a DSP-based VME platform to help develop a practical technology for imaging the three-dimensional structure of individual molecules.
Upgraded VME board has more power and peripherals
Due to strong demand for the industry's first onboard, one-slot Fibre Channel VME board, Pentek now offers additional I/O, memory and real-time processing options.
Up to four front panel dataport (FPDP II) connectors deliver output data at up to 320Mbyte/s each.
A VXS interface provides two 1.25Gbyte/s switched serial fabric ports to the VME backplane.
Targeting extremely high-performance DSP tasks, the Pentek Model 6822 couples its high-speed ADCs to two Xilinx Virtex-II Pro FPGAs, each supported by 16Mbyte of Flash and 128Mbyte of SDRAM.

Multiband receivers made for CompactPCI systems
Pentek has made its first foray into the cPCI market with 16- and 32-channel multiband-receiver boards featuring 14bit A/D convertors and Virtex-II FPGAs for signal processing.
Each 128Mbyte SDRAM can be used as a circular buffer digital delay or as real-time transient capture memory.
Each XC2VP50 FPGA provides the equivalent of 6 million system gates, allowing users to perform critical real-time, high-frequency signal processing tasks such as demodulation, convolution, filtering and data analysis operations onboard.
This can reduce the datarate of offboard traffic in many applications.
Other applications can take advantage of high-speed I/O at both the front panel and backplane that support the board's highest datarates.
A key feature of the Model 6822 is the VXS port on the P0 backplane connector, which makes it one of the first boards in the industry to offer VXS.
The port follows the VITA 41 specification for VME backplane switched serial fabrics and supports several different protocols through installation of one of the various fabric IP cores now available.
The initial release of the Model 6822 supports Serial RapidIO (VITA 41.2) and the Xilinx Aurora link layer protocols over the VXS port.
There are plans to extend support to include PCI-Express.
The front panel accepts two analogue inputs and delivers digital output samples over two FPDP or FPDP II connectors.
An optional two-slot version of the card offers two more FPDP or LVDS connectors for digital output data.
As an alternative to the front-panel data connectors, an optional 24-pair LVDS data channel through the P2 backplane connector is also available.
In addition, a front panel sync/timing bus facilitates synchronous, triggered data acquisition across multiple boards.
This capability is essential for multichannel applications such as radar beamforming and direction finding.
The Model 6822 marks the extension of Pentek's board offerings into the full range of ruggedisation levels.
The board is available in commercial (L0), air-cooled (L1, L2) and conduction-cooled (L3, L4) versions.
"This is Pentek's first product designed from the ground up for multiple versions to cover the full range of environmental specs", says Rodger Hosking, Vice President of Pentek "These new boards can operate in a broad range of severe environments, including unmanned military reconnaissance vehicles, airborne radars and maritime communications systems, providing the most demanding customers with the same state-of-the-art technology available to commercial users".
The Model 6822 includes full development tool support for the onboard FPGAs, featuring Pentek's GateFlow FPGA resources.
Tools include the GateFlow FPGA Design Kit supporting user-defined FPGA algorithms; the GateFlow IP Core Library for high-performance FFTs; 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.
One such GateFlow offering, the wideband digital receiver IP Core 422, offers a complete FPGA-based digital down-convertor function for the Model 6822 with user-programmable filter coefficients, tuning frequency and decimation.
The Model 6822 dual-channel A/D VME board with Virtex-II Pro FPGAs and VXS I/O is immediately available starting at US $8995.
Delivery is 12 weeks ARO.
