Pentek, Inc. has announced the newest member of its Jade family of high-speed data converter XMC FPGA modules: the two-channel Jade Model 71865, a 200 MHz 16-bit A/D channelizer with 762 narrowband digital down converters (DDCs) and four wideband DDCs, based on the Xilinx Kintex UltraScale FPGA. The Model 71865 is an economical and energy efficient, complete software radio receiver solution for commercial, military, and government high-channel count applications.

The Model 71865 functions include two A/D acquisition IP modules for simplifying data capture and transfer. From each of the two acquisition modules, A/D sample data flows into identical IP modules consisting of banks of wideband and narrowband DDCs. Finally, data is delivered to four DMA controllers linked to the PCIe Gen.3 x8 interface for transfer to a signal processor.

The four wideband DDCs can be set for decimation values between 8 and 128 in steps of four, providing usable output bandwidths from 1.25 MHz to 20 MHz. The wideband DDCs can be effective in locating signals.

Each of the six narrowband DDC banks can be configured to operate in three different modes, where each mode provides a different quantity of DDC channels and range of decimations. Output bandwidths range from 20 kHz to 1.25 MHz. All DDCs can be independently tuned from 0 Hz to 200 MHz with 32 bits of resolution.

Three banks of resampling filters accept input samples from each narrowband DDC at one sample rate and deliver output samples at another rate. Resampling filters are often used for better symbol recovery of signals using modern digital modulation schemes. Programmable ratios ensure flexibility to cover a wide range of wireless standards.

Pentek’s Navigator BSP provides a full suite of high-level C-callable libraries that support all features of the Model 71865 and demonstrate all of its functional modes with examples. The software package is provided with complete source code allowing the user to modify and integrate this functionality into the end application. Navigator BSP also includes an extremely useful Signal Viewer utility that allows developers to view digitized signals from the output samples of any DDC in time and frequency domain.

SPARK development systems are ready for immediate operation with software and hardware installed. In many applications, the SPARK development system can become the final deployed application platform.
