Press Release Summary:

January 23, 2013 - Preconfigured with programmable 1- or 2-channel digital downconverter loaded into onboard Xilinx Virtex-6 FPGA, Model 71641 is capable of digitizing one 12-bit channel at 3.6 GHz or 2 channels at 1.8 GHz. Each DDC has independent 32-bit tuning frequency programmable from DC to ƒs, where ƒs is A/D sampling frequency. In single channel mode, DDC decimation can be programmed to 8x, 16x, or 32x. In dual channel mode, both channels share same decimation rate, programmable to 4x, 8x, or 16x.

Pentek Expands Product Line with Digital Downconverter for Wideband Radar and SDR Applications

Press release date: January 21, 2013

  • 3.6 GHz data acquisition with 12-bit resolution
  • Single- and dual-channel operation with multi-board synchronization
  • Digital downconverter delivers up to 360 MHz baseband output bandwidths
  • 2 GB deep on-board memory and high-speed serial I/O
LONG BEACH, CA, Embedded Tech Trends–Pentek, Inc., today announced an enhancement to its fastest-ever data acquisition XMC module for the popular CobaltĀ® family. The Model 71641, capable of digitizing one 12-bit channel at 3.6 GHz, or two channels at 1.8 GHz, comes preconfigured with a programmable one- or two-channel digital downconverter (DDC) loaded into the onboard Xilinx Virtex-6 FPGA. The new module is ideal for wideband radar and software defined radio (SDR) applications.

“The Model 71641 is designed to acquire very wide bandwidth radar and communications signals so they can be efficiently delivered and processed,” said Rodger Hosking, vice president of Pentek. “An extraordinary amount of Pentek engineering went into making this DDC IP core easy to use, even at these extreme data rates,” he added. The complex DDC IP core of the 71641 is preconfigured and characterized for a turn-key, out-of-the-box solution.

DDC IP Core
Within the Virtex-6 FPGA is a powerful Pentek designed DDC IP core. The core supports single and dual channel modes, accepting data samples from the analog to digital (A/D) converter at the full 3.6 GHz rate in single-channel mode or 1.8 GHz in two-channel operation.

Each DDC has an independent 32-bit tuning frequency programmable from DC to ƒs, where ƒs is the A/D sampling frequency. In single channel mode, DDC decimation can be programmed to 8x, 16x or 32x. In dual channel mode, both channels share the same decimation rate, programmable to 4x, 8x or 16x.

The decimating filter for each DDC accepts a unique set of user-supplied 16-bit coefficients. The 80% default filters deliver an output bandwidth of 0.8*ƒs/N, where N is the decimation setting. In single channel mode the maximum output bandwidth is 360 MHz. Rejection of adjacent-band components within the 80% output bandwidth is better than 100 dB. Each DDC delivers a complex output stream consisting of 24-bit I + 24-bit Q or 16-bit I + 16-bit Q samples at a rate of ƒs/N

Supporting Features and Products
Pentek’s ReadyFlow Board Support package for Windows, Linux or VxWorks operating systems includes C-callable libraries, drivers and example code for easy access to all of the Model 71641 features.

Pricing and Availability
The Model 71641 starts at $23,695 USD. Delivery is 8-10 weeks ARO. Pricing varies depending on the options chosen.
