bc824VXI

VXI Rubidium Frequency Reference

The bc824VXI Rubidium Frequency Standard is an ultra stable miniature atomic oscillator supported by C-size mainframe and resource manager configured in accordance with the VXIbus specification. The timing card will provide ultra stable 10MHz sine wave or TTL outputs with minimal added noise.

Symmetricom’s bc824VXI employs both a rubidium oscillator and a low phase noise ovenized crystal oscillator (OCXO).

Exceptional Long Term Stability and Noise Floor
The rubidium oscillator provides exceptional long term stability if the synchronizing input is lost. The OCXO, phase locked to the rubidium oscillator, removes rubidium frequency spurs, providing an excellent noise floor.

Register and Message-Based Device
The VXIbus Rubidium Frequency Standard Plug-in card is a register based device as well as a message based device. The message based interface capability will provide minimal access latency to the card via the system bus. The capability of the interrupt generation will allow interrupt driven algorithms to interface to the card. The bc824VXI will synchronize to an external 1PPS, 10 MHz reference or IRIG B time code.

Reliable and Redundant
If the input source is lost, then time will be maintained in a flywheel state based on the on-board rubidium standard.
