UPPER SADDLE RIVER, N.J. – Pentek Inc. in Upper Saddle River, N.J., is introducing the 2-channel Jade model 71865 200 MHz 16-bit A/D channelizer for commercial, military and government high-channel count software radio receiveapplications.
The Jade 71865 high-speed data converter Switched Mezzanine Card (XMC) field-programmable gate array (FPGA) module has 762 narrowband digital down converters (DDCs), four wideband DDCs, and is based on the Xilinx Kintex UltraScale FPGA.
The model 71865 functions include two A/D acquisition IP modules for simplifying data capture and transfer. Each acquisition IP module has a controller for all data clocking, triggering, and synchronization functions.
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 direct memory access (DMA) controllers linked to the PCI Express Gen.3 x8 interface for transfer to a signal processor.
Users can set the four wideband DDCs for decimation values between eight and 128 in steps of four, providing usable output bandwidths from 1.25 MHz to 20 MHz. The wideband DDCs can help locate signals of interest.

Users can configure each of the six narrowband DDC banks 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 tuned independently 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 often are used for better symbol recoof signals using modern digital modulation schemes. Programmable ratios ensure flexibility to cover a wide range of wireless standards.
Pentek's Navigator BSP provides a suite of high-level C-callable libraries. The software package comes with source code to enable th user to modify and integrate this functionality into the end application.
Navigator BSP also includes a signal viewer utility that to help developers view digitized signals from the output samples of any DDC in time and frequency domain. SPARK development systems are ready for operation with software and hardware installed.
