Pentek introduces Model 54851 3U VPX boards

April 29, 2019 ‚îÄ Pentek introduced the Model 54851 of the Jade family of 3U VPX boards. The Model 54851 is based on the Xilinx Kintex Ultrascale FPGA and features two 500 MHz 12-bit A/Ds with two programmable multiband digital down converters (DDCs) and one digital up converter (DUC) with two 800 MHz 16-bit D/As. The 54851 is the first board utilizing this 3U VPX architecture with wideband I/O options.

The Model 54851 uses VPX I/O options for RF and optical interconnects through the VPX backplane:

  • Option -110: Optical connections based on VITA 66.5 (draft), containing blind-mate MT optical connectors with fixed contacts on the plug-in module and floating displacement on the backplane.
  • Option -111: RF connections based on ANSI/VITA 67.2, containing multi-position blind-mate analog connectors with SMPM contacts.
  • Option -112: RF connections based on ANSI/VITA 67.3 type C, containing multi-position blind mate analog connectors with SMPM contacts, spring-loaded on the backplane.

Future options for higher density optical and RF connectors are planned as the supporting standards become available. Organizations such as The Open Group Sensor Open Systems Architecture (SOSA) Consortium are specifying additional types and apertures for VITA 67.3.

The Model 54851 can be populated with a range of Kintex UltraScale FPGAs to match specific requirements of the processing task, spanning from the entry-level KU035 (with 1,700 DSP slices) to the KU115 (with 5,520 DSP slices). The KU115 is designed for modulation/demodulation, encoding/decoding, encryption/decryption, and channelization of the signals between transmission and reception.

The Model 54851 also includes a multi-board clock and sync engine and DDR4 memory. In addition to supporting PCI Express Gen. 3 as a native interface, the Model 54851 includes optional high-bandwidth connections to the Kintex UltraScale FPGA for custom digital I/O.

With the Xilinx Kintex Ultrascale FPGA, data converters and optical or RF I/O, the Model 54851 becomes an interface to HF or IF ports of a communications or radar system.
