Manufacturer's description:

The Symmetricom bc635PCI-U timing module provides precision time and frequency reference to the host computer and peripheral data acquisition systems. Time is typically acquired from time code signals such as IRIG B. The bc635PCI-U automatically supports both the 3.3V and 5.0V signaling of the PCI bus. Integration of the module is easily facilitated with optional drivers for Windows 2000/XP, Linux or Solaris.

Central to the operation of the module is adisciplined 10 MHz oscillator and 100nanosecond clock. Current time (days to 100nanoseconds) can be accessed across the PCIbus with zero latency, which allows for veryhigh speed time requests. The on-board oscillator is rate-matched (disciplined) to the inputtime source and drives the precision 10 MHzfrequency output and time code generatorcircuitry. If the time input is lost, the modulewill continue to maintain time (flywheel). Ifpower is lost, a battery-backed clock isavailable to maintain time.

Both time code generation and translation are supported. The generator supplies IRIG B time code output that is synchronized to the input time source. The translator reads IRIG A, IRIG B and IEEE-1344 time codes.

An Event Time Capture feature provides a means of latching time for an external event input. The module can also be programmed to generate a periodic pulse rate as well as generate a single interrupt at a predetermined time (Time Compare).

A key feature of the bc635PCI-U 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. The external frequency input is a unique feature allowing the internal timing of the bc635PCI-U to slave to the 10 MHz output from a Cesium or Rubidium standard. This creates an extremely stable PCI based clock for all bc635PCI-U timing functions and is superior to any disciplining technique.
