High-Speed Synchronizer and Distribution Board Locks In Up to 64 Channels

Sept. 29, 2020
Board syncs sampling, data acquisition, gating, and triggering for multichannel phase-coherent systems.

Fans of Pentek’s Quartz family of RFSoC FPGA boards will find broad usage for a new family member: the Model 5903, a 3U VPX high-speed synchronizer and distribution board. The 5903 synchronizes up to eight 8-channel Quartz family boards within a system, enabling synchronous sampling and timing for a wide range of multichannel high-speed data acquisition, DSP, radar, beamforming, 5G, electronic warfare, and software-radio applications.

It can be quite complicated to precisely synchronize multi-channel system implementations, but with the Model 5903, users with high-channel-count, phase-coherent applications can start development without burning time and money on synchronization strategies. An on-board programmable clock generator creates the sample clock and complementary timing signals. Up to eight Quartz boards, with eight channels each (up to 64 channels total), can be synchronized using the Model 5903, to support synchronous sampling, triggering, and gating functions across all boards.

The Model 5903 provides four front-panel MMCX connectors to accept input signals from external sources: one for a reference clock, one for sync, and two for gate/trigger signals. The internal programmable clock generator can create sample clock frequencies from 1 to >5 GHz. The sample clock can be locked to the internal 100-MHz frequency reference or locked to an external reference input connector. Similarly, sync and gate/trigger signals can be generated on-board via software or received from external sources through the sync and gate/trigger input connectors.

All board modes and operations are controlled by an on-board processor. Commands to this processor are sent via USB either through a front-panel port or through the rear transition module (RTM). The Pentek Navigator board-support software package provided with Quartz boards includes configuration utilities for the Model 5903.

The Model 5903 delivers a multi-signal sync bus to each board to be synchronized containing sample clocks, reference clocks, and gate/trigger and sync signals. Four sync buses are provided on the Model 5903’s front panel and four are provided to the VPX backplane and optionally to an RTM. Connections between boards are facilitated across the VPX backplane and through precision matched multi-signal sync cables that come with the Model 5903.

The Model 5903 is suited for use with the Pentek’s 8-channel A/D and D/A boards based on Xilinx’s Zynq UltraScale+ RFSoC processor: Model 5550 and Model 5950 3U VPX boards and the Model 7050 PCIe board.

Designed for air- and conduction-cooled environments, the Model 5903 board starts at $7,000. Options for front-panel and RTM sync connections are available. The Model 5903 is available now with delivery at 8-10 weeks ARO.
