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. This product employs both a rubidium oscillator and a low phase noise ovenized crystal oscillator (OCXO). 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.

The VXIbus Rubidium Frequency Standard (VRFS) card is a register-based device as well as a message based device. The message based interface capability provides minimal access latency to the card via the system bus.

The bc824VXI will synchronize to an external 1 PPS, 10 MHz reference or IRIG time code. If the input source is lost, time is maintained in a flywheel state based on the on-board rubidium standard.
