bc637PCIe (GPS)

GPS Referenced PCI Express Time & Frequency Processor

Symmetricom's bc637PCIe PCI Express timing module provides unparalleled precise time and frequency to the host computer and peripheral systems. Time is typically acquired from GPS or time code signals such as IRIG B.

Extremely Precise time is acquired from the GPS satellite system or from time code signals provided to the host computer. GPS synchronization provides 170 nanosecond RMS accurate time to UTC (USNO) and enables the bc637PCIe to be an ideal master clock for precisely synchronizing one or more computers to UTC.

Integration of the module is easily facilitated with standard drivers for Windows, Linux, and Solaris that included with the module.

Extensive time code generation and translation are supported. The generator outputs eitherIRIG A, B, G, E, IEEE 1344, NASA 36, XR3 or 2137 in both amplitude modulated (AM) and DC level shift (DCLS) formats. The translator reads and may be used to discipline the 10 MHz oscillator to either the AM or DCLS format of IRIG A, B, G, E, IEEE 1344, NASA 36, XR3 or 2137 time codes.

The module also has a state-of-the-art DDS rate synthesizer capable of 0.0000001 PPS to 100 MPPS. Three Event Time Capture registers provide a means of latching time of external events.   A key feature of the bc635PCIe is the ability to generate interrupts on the PCI bus at programmable rates. These interrupts can be used to synchronize applications on the host computer as well as signal specific events.
