Pentek 7141 Dual Multiband Transceiver with FPGA - PMC/XMC

  • Two 125 MHz 14-Bit A/Ds
  • Input Signal Bandwidth: 50 MHz
  • Four Digital Downconverters
  • One Digital Upconverter
  • Two 500 MHz 16-bit D/As
  • 512 MB of DDR SDRAM


The Pentek 7141 Dual Multiband Transceiver with FPGA - PMC/XMC is a software radio transceiver suitable for connection to HF or IF ports of a communications system. It includes two A/D and two D/A converters capable of bandwidths to 50 MHz and above. The 7141 uses the popular PMC format and supports the emerging VITA 42 XMC standard with optional switched fabric interfaces.

The front end accepts two full scale analog HF or IF inputs on front panel MMCX connectors at +10 dBm into 50 ohms with transformer coupling for the LTC2255 14-bit 125MHz A/Ds. The digital outputs are delivered into the Virtex-II Pro FPGA for signal processing or for routing to other module resources.

A TI/Graychip GC4016 quad digital downconverter accepts either four 14-bit inputs or three 16-bit digital inputs from the FPGA, which determines the source of GC4016 input data. These sources include the A/D converters, FPGA signal processing engines, SDRAM delay memory and data sources on the PCI bus. Each GC4016 channel may be set for independent tuning frequency and bandwidth. For an A/D sample clock frequency of 100 MHz, the output bandwidth for each channel ranges from 5 kHz up to 2.5 MHz. By combining two or four channels, output bandwidth of up to 5 or 10 MHz can be achieved.

A TI DAC5686 digital upconverter (DUC) and dual D/A accepts baseband real or complex data streams from the FPGA with signal bandwidths up to 40 MHz. When operating as an upconverter, it interpolates and translates real or complex baseband input signals to any IF center frequency between DC and 160 MHz. It delivers real or quadrature (I+Q) analog outputs through two 320 MHz 16-bit D/A converters to two front panel MMCX connectors at +4 dBm into 50 ohms. If translation is disabled, the DAC5686 acts as a two channel interpolating 16-bit D/A with output sampling rates up to 500 MHz.

The Xilinx XC2VP50 Virtex-II Pro FPGA serves as a control and status engine with data and programming interfaces to each of the on-board resources including the A/D converters, GC4016 digital downconverter, digital upconverter and D/A converters. Factory installed FPGA functions include data multiplexing, channel selection, data packing, gating, triggering and SDRAM memory control. Option -104 adds the P4 PMC connector with 32 pairs of LVDS connections to the Virtex-II Pro FPGA for custom I/O. The FPGA includes two PowerPC cores which can be used as local microcontrollers to create complete application engines.

Two independent internal timing buses can provide either a single clock or two different clock rates for the input and output signals. Each timing bus includes a clock, a sync, and a gate or trigger signal. Signals from either Timing Bus A or B can be selected as the timing source for the A/Ds, the downconverter, the upconverter and the D/As. Two external reference clocks are accepted, one for each timing bus and two internal clocks may be used for each timing bus. A front panel 26-pin LVDS Clock/Sync connector allows multiple modules to be synchronized. In the slave mode, it accepts differential LVDS inputs that drive the clock, sync and gate signals for the two internal timing buses. In the master mode, the LVDS bus can drive one or both sets of timing signals from the two internal timing buses for synchronizing multiple modules. Up to seven slave 7141's, can be driven from the LVDS bus master, supporting synchronous sampling and sync functions across all connected boards. Up to 80 modules may be synchronized with a Model 9190 Clock and Sync Generator.

Three independent banks of SDRAM are available to the FPGA. Built-in memory functions include an A/D data transient capture mode with pre- and post-triggering; a D/A waveform generator mode; and an A/D data delay mode for applications such as tracking receivers. The SDRAMs are also available as a resource for the two PowerPC processor cores within the FPGA. A 16 MB FLASH memory supports booting and program store for these processors.

Model 7141 includes an industry-standard interface fully compliant with PCI 2.2 bus specifications. The interface includes nine separate DMA controllers for efficient transfers to and from the module. Data widths of 32 or 64 bits and data rates of 33 or 66 MHz are supported.

Model 7141 complies with the VITA 42.0 XMC specification for carrier boards. This emerging standard provides, among others, for a 4X link with a 3.125 GHz bit clock between the XMC module and the carrier board. With two 4X links, the 7141 achieves 2.5 GB/sec streaming data transfer rate independent of the PCI interface and supports switched fabric protocols such as Serial RapidIO and PCI Express.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
