Pentek introduces A/D and D/A converter embedded computing modules for data acquisition


Pentek Inc. in Upper Saddle River, N.J., is introducing two turn-key multichannel high-speed analog-to-digital (A/D) and digital-to-analog (D/A) converters for data acquisition and signal-generation embedded computing applications.

The FlexorSet model 5973-313 for 3U VPX and model 7070-313 for PCI Express. These consist of an FPGA Mezzanine Card (FMC) installed on either of two Flexor FMC carriers with Virtex-7 field-programmable gate arrays (FPGAs).

The Flexor model 3312 FMC features four 250 MHz, 16-bit A/D converters and two 800 MHz, 16-bit D/A converters, which are supported with matching digital down converters (DDCs) and interpolation filters as intellectual property (IP) installed in the FPGA.

Each FlexorSet is a multichannel, high-speed data converter subsystem with programmable analog I/O signal interface suitable for connection to HF or IF ports of a communications or radar system, and supporting signal bandwidths to 100 MHz.

The built-in data capture and playback features offer solutions as well development platform for custom FPGA-processing IP.

Each includes four 250 MHz, 16-bit A/Ds using two Texas Instruments (TI) ADS42LB69s. One TI DAC5688 provides a digital upconverter and two 800 MHz, 16-bit D/As. Four banks of DDR3 SDRAM provide four gigabytes of data storage.

The model 5973-313 and model 7070-313 include optional copper and optical gigabit serial connections to the Virtex-7 FPGA for custom I/O.
