Pentek Inc. has announced the latest member of its Flexor portfolio of FPGA mezzanine card (FMC) modules. According to the company, the Flexor Model 3316 is a multichannel, high speed data converter FMC that doubles the existing channel density and boosts sample rates with eight 250MHz 16bit ADCs.

The front end accepts eight analogue HF or IF inputs on front panel connectors transformer coupled to four TI ADS42LB69 dual ADCs. The high pin-count FMC connector is geared matched to the Pentek Model 5973 3U VPX Virtex-7 FPGA carrier for high channel count deployable systems. Pentek also supplies 3316 example code for the Xilinx PCIe FMC 707 Virtex-7 evaluation board as an alternate development scenario.

Flexor Model 3316

An internal timing bus provides all timing and synchronisation required by the ADCs. An on-board clock generator can receive an external sample clock from the front panel coaxial connector that can be used directly as the sample clock or divided by a built-in clock synthesiser circuit. Alternately, the sample clock can be sourced from an on-board programmable VCXO where the front panel coaxial connector can be used to provide a 10MHz reference clock to phase-lock the internal oscillator.

The Flexor Model 5973 comes preconfigured with a suite of built-in functions for data capture, synchronisation, time tagging and formatting, all tailored and optimised for specific FMC modules, including the Flexor Model 3316. These standard Model 5973 functions, plus eight digital down converters (DDCs), enable high performance data capture and transfer modes to provide an ideal turn-key signal interface for radar, communications, or general data acquisition applications, eliminating the integration effort typically left for the user when integrating FMC and carrier.

With a Pentek carrier, developers have an ideal development and deployment platform for applications requiring custom IP. The Pentek GateFlow FPGA design kit gives users access to the complete factory installed IP at the source level, allowing them to extend or even replace the built in functions, noted the company.

The Pentek GateXpress PCIe configuration manager supports dynamic FPGA reconfiguration though software commands as part of the runtime application. This provides an efficient way to quickly reload the FPGA, which normally occurs many times during development. For deployed environments, GateXpress enables reloading the FPGA without the need to reset the host system, intended for applications that require dynamic access to different IP algorithms or for live updates.

The Pentek ReadyFlow BSP is available for Windows and Linux. ReadyFlow consists of a C-callable library, a complete suite of initialisation, control and status functions, as well as a rich set of precompiled, ready-to-run-examples to accelerate application development.

The Flexor Model 3316 FMC is designed for air-cooled, conduction-cooled, and rugged operating environments. The Model 3316 price starts at $3,495 when purchased with the Model 5973 FMC carrier. Delivery is 8-10 weeks ARO.
