The GPS-referenced bc637PCIe timing module provides precise time and frequency functions to the host computer and peripheral systems.

Precise time is acquired from the GPS satellite system or from time code signals. GPS synchronization provides 170 ns RMS accurate time to UTC (USNO) enabling the bc637PCIe to precisely synchronize multiple computers to UTC.

Precise Time

The bc637PCIe provides precise time on request and a fast response to host applications. The request for time is made using SDK software functions which are included as standard with the module.

Multiple Time Codes

The bc637PCIe has a wides time code input and output support available in any bus level timing card. Support is available for 30 different time codes.

Measure External or Internal Events

It allows you to measure the exact time up to the occurrence of three independent external events.

Flexible Rate Generation

The DDS on the timing module can be programmed to generate rates up to 100MPPS or as little as once every 115 days.
