Upper Saddle River, NJ - August 24, 2009 - Pentek today announced the newest system-enhancing product that makes it easier for Pentek customers to configure multiple-channel systems. The Model 6891 VME board is well suited 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.
"Many of our customers need to synchronize multiple channels to satisfy their system requirements. For larger systems, this means delivering timing signals to multiple boards and even multiple chassis," said Rodger Hosking, vice president, Pentek, Inc. "Contrary to many competitive offerings that leave the user on his own to develop a way to synchronize and distribute timing signals within a system, this new board provides a ready-to-use, simplified and reliable solution to this critical system issue, saving the user both development time and resources."
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 6891 provides up to eight timing signal cables fully compatible with the multi-pin front panel timing signal connectors found on all recent Pentek PMC modules. Using this strategy, 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.
"Users can typically synchronize two, three or four boards by joining the timing signal connectors with a ribbon cable," noted Robert Sgandurra, product manager for Pentek, Inc. "In this case, one board acts as a driver and the other modules as receivers. But as systems grow larger with more channels and more than four modules, a product such as the 6891 becomes essential."
By using the 6891, loading is no longer an issue because each board is driven over a dedicated timing signal cable by one of its eight dedicated drivers. What's more, passing the clock, sync, gating and trigger signals through individual cables guarantees better performance due to improved delay matching.
From the standpoint of economy of packaging, 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.
