Rubidium Specification Part No. + Packaging: LFRBXO059244Bulk Description The IQRB-1 rubidium oscillator is a sub-miniature atomic clock exhibiting normal rubidium oscillator performance in a 65cc OCXO style package. This rubidium oscillator has 100 times less drift than OCXOs and with short term stability of 0.008ppb/s at 100s, this rubidium oscillator provides significant improvements in performance over OCXOs. Model IQRB-1 Model Issue number 2 Frequency Parameters 10.0MHz Frequency Frequency Tolerance 0.05ppb Tolerance Condition 25C Frequency Stability 0.50ppb Operating Temperature Range -30.00 to 65.00C Short Term Stability (AVAR): Outline (mm) 1s 0.08ppb 10s 0.03ppb 100s 0.008ppb Ageing: Day 0.005ppb Month 0.05ppb Magnetic Field Sensitivity, DC (2 Gauss): 0.04ppb/Gauss max Temperature Coefficient (ambient): 5x10 (0 to 50C) Retrace: 0.02ppb max Electrical Parameters 12.0V Supply Voltage Note: The device will operate over the Supply Voltage Range 12V to 18V. Input Power ( 25C): 6W 12V, 1.2A max. Warm Up Time: 5mins to lock 25C. Lock Monitor: Pin 2 is high (5V) when out of lock and low (0V) when locked. Frequency Adjustment Pulling 5ppb min Control Voltage 2.5V 2.5V Input Impedance 10k min Control Voltage Input Current (Pin 1 swept from 0V to 5V): 40uA typ Control Voltage Input Capacitance (Pin 1): 5pF typ Note: The oscillator will detect if no control voltage is applied to Pin 1 and will automatically set the control voltage internally to 2.5V. Further when the oscillator is locked Pin 1 (frequency control) is set to internal default voltage 2.5V. However if a voltage is applied (even GND) to Pin 1 then the oscillator will switch to accept an external control voltage input.

Manufacturing Details MTBF (Stationary): Approx 100000hrs Note: In regard to PCB layout the oscillator base plate runs hot and it is not a good idea to place components on the opposite side of the PCB to the rubidium module as the base plate can be 85C depending upon environmental conditions. We recommend leaving about a 5mm minimum gap around the rubidium module wherever possible.
