Pentek Model 6891 System Synchronizer and Distribution VME Board

Pentek introduced the Model 6891 VME board. The 6891 board accepts clock, sync, gate and trigger signals as inputs, and delivers buffered versions of these signals to other modules in the system to ensure synchronous sampling and data collection across all connected modules. The Pentek 6891 is ideal for radar beamforming, direction finding, and shipboard diversity reception and cellular wireless applications where multiple antennas are used to steer and/or improve the reception of signals. The 6891 is available now with prices starting at $3,995 USD, which includes free lifetime support. Delivery is 8 weeks ARO.

Pentek Model 6891 System Synchronizer and Distribution Board Features

  • Synchronizes up to eight separate I/O modules
  • Up to eight 6891 VME boards can be linked to synchronize 64 I/O modules
  • Synchronizes sampling and data acquisition for multichannel systems
  • Synchronizes gating and triggering functions
  • Clock rates up to 500 MHz
  • Front panel SMA connectors for input signals
  • Front panel 26-pin Sync Bus connectors compatible with a wide range of Pentek I/O modules
  • Single-slot 6U VME board configuration

The Pentek 6891 VME board features up to eight timing signal cables that are fully compatible with the multi-pin front panel timing signal connectors found on all recent Pentek PMC modules. Up to eight modules can receive a common clock up to 500 MHz along with timing signals. For larger systems, up to eight 6891 VME boards can be linked together providing synchronization for 64 I/O modules producing systems with up to 256 channels.

Engineers can typically synchronize two, three, or four boards by joining the timing signal connectors with a ribbon cable. In this case, one board acts as a driver and the other modules as receivers.

By using the 6891 module, loading is no longer an issue because each board is driven over a dedicated timing signal cable by one of its eight dedicated drivers. Passing the clock, sync, gating and trigger signals through individual cables guarantees better performance due to improved delay matching.

The 6891 occupies a single VME slot. It often eliminates the need for a custom external timing signal generator chassis, providing a more compact and less expensive system solution. The 6891 requires no additional software. The modules connected to the 6891 board are already fully supported by ReadyFlow board support packages for Linux, VxWorks and Windows operating systems.
