Symmetricom bc635PCI-U OCXO 10MHz Timing Frequency Synthesizer IRIG-B PCI Card [New]
( 362393328111) )
Brand New • High Stability OCXO Oscillator • Reads IRIG-B • Precision Event Timer • PCI Card
An unused new (old stock) precision timecode I/O card for a PCI slot. This is the version of the card with a high stability OCXO oscillator installed. It does not have a GPS receiver. Seller warranty does not cover the on-board button cell which has a finite life.
The Symmetricom bc635PCl-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 IRlG B. The bc635PCl-U automatically supports both the 3.3V and 5.0V signaling over the PCI bus. Integration of the module is easily facilitated with optional drivers for Windows, Linux or Solaris.
Central to the operation of the module is a disciplined 10 MHz oscillator and 100 nanosecond clock. Current time (days to 100 nanoseconds) can be accessed across the PCI bus with zero Latency, which allows for very high speed time requests. The on-board oscillator is rate-matched (disciplined) to the input time source and drives the precision 10 MHz frequency output and time code generator circuitry. If the time input is lost, the module will continue to maintain time (flywheel) If power is lost, a battery-backed clock is available 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 bc635PCl-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 bc635PCl-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.
