GPS Referenced PCI Express Time & Frequency Processor
Product Information
Product Information
Microchip’s bc637PCIe PCI express timing module provides extremely accurate time and frequency to the host computer and peripheral systems. Time is typically acquired from time code signals such as IRIG B.The module is easily integrated with standard drivers for Windows, Linux, and Solaris is available for download.
Supporting extensive time code generation and translation, the generator outputs either IRIG 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 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 synchronise applications on the host computer as well as signal specific events.
