Here's a lightly used PCIe GPS time sync card for a computer that allows you to use the network of atomic clocks within the GPS satellite system to obtain highly accurate time, and if required to output a highly accurate GPS-disciplined pulse rate, frequency or timecode. It will not work in a PCI slot. A basic test antenna is inclued - see photos. The antenna voltage is 5V. The antenna jack is a SMB type. The included antenna is provided to help you test the card, but please note that your antenna will need to be outdoors with a full view of the sky to achieve sync reliably. It will not achieve sync behind a window. The on-board battery has recently been replaced. The board has been updated to the latest firmware version that I have in my archive and therefore shows the correct date - see screenshots taken while testing the actual card for sale. Note that I do not have the full software suite for this card. I only have a basic test application. The buyer may need to contact Microsemi to obtain those files if they are needed.

Overview

The GPS-referenced bc637PCIe timing module provides unparalleled 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. Integration into a custom application is easy and very efficient through the use of the full-featured Windows and Linux SDKs/drivers.
Extensive time code generation and translation are both supported. The translator reads and disciplines the internal oscillator to either the amplitude modulated (AM) and DC Level Shift (DCLS) formats of IRIG A, B, G, E, IEEE 1344,
NASA 36, XR3, or 2137 time codes. The generator outputs either IRIG A, B, G, E, IEEE 1344, NASA 36, XR3 or 2137 in both AM and/or DCLS formats.
Central to the operation of the module is a disciplined TCXO 10 MHz oscillator that provides the timing module’s 100 ns clock. Current time (days to 100 ns) can be accessed across the PCIe bus with no PCIe bus wait states, which allows for very high-speed, low-latency time requests. The 10 MHz oscillator drives the module’s frequency and time code generator circuitry. If the input reference is lost, the module will maintain time (flywheel) based on the 10 MHz oscillator’s drift rate. If power is lost, a battery backed Real-Time Clock (RTC) maintains the time.
The module has a state of the art Direct Digital Synthesizer (DDS) rate synthesizer with a range from 0.0000001 PPS to 100 MPPS. The module may also be programmed to generate an interrupt at a precise predetermined time based on a time compare (strobe). Three Event Time Capture inputs provide a means of latching time of different external events.
A key feature of the bc637PCIe is the ability to generate interrupts on the PCIe bus at programmable rates. These interrupts can be used to synchronize applications on the host computer as well as signal specific timing events over the bus.
The unique external frequency input allows the time and frequency of the bc637PCIe to be derived from an external oscillator that may also be disciplined (DAC voltage controlled) based on the selected input reference. The module may be operated in generator (undisciplined) mode where an external 10 MHz from a Cesium or Rubidium standard is used as the frequency reference. This creates an extremely stable PCIe-based clock for all bc637PCIe timing functions.
