Pentek Inc. has launched a single-channel 6U VMEbus board featuring one of the fastest 12-bit ADC in the market with sampling rates to 210MHz.

Targeting high-performance DSP tasks, the Model 6821 couples the ADC to two Virtex-II Pro FPGAs by Xilinx. It 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 LVDS bus supports synchronous, triggered data acquisition across multiple boards.

The 6821 has two XC2VP20 or XC2VP50 devices, each with up to 6 million system gates and as many as 232 hardware multipliers. The multipliers, along with generous on-chip configurable RAM, make the FPGAs suitable for handing real-time DSP algorithms at the 210MHz A/D sampling rate.

The two FPGAs are also optionally equipped with 128MB of SDRAM for data delay and buffering capacities. Two 16MB flash memories support boot operations for optional use of the embedded FPGA microcontrollers. Four FPDP output ports, two for each FPGA, support data transfer rates of 320MBps 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.

VP Rodger Hosking, said, "Our new 6821 can be used as a standalone system or as a powerful front-end preprocessor for Motorola G4 PowerPC and Texas Instruments C6000 DSP boards."

Pricing for the VME board starts at $7,595 and lead time is 12 weeks ARO.
