Rubidium Oscillator Specification Part No. + Packaging: LFRBXO059244Bulk Customer Part: Description The IQRB-1 rubidium oscillator is a sub-miniature atomic clock in a 65cc OCXO style package. Model IQRB-1 Model Issue number 5 Frequency Parameters 10.0MHz Frequency Frequency Stability 1.50ppb Operating Temperature Range -30.00 to 65.00C Ageing: Day 0.005ppb Month 0.05ppb Frequency Stability (Temperature varied across the operating temperature range, measurement referenced to frequency observed with fref=(fmax, fmin)/2) : 0.5ppb typical Retrace: 0.02ppb max Magnetic Field Sensitivity, DC (2 Gauss): 0.04ppb/Gauss Outline (mm) max Electrical Parameters Supply Voltage 12.0V Note: The device will operate over the Supply Voltage Range 12V to 18V Start-up Current (Vs=12V, 25C): 1.7A max Initial Spike: 2.5A max for 10ms max Warm up time: 5mins to lock status, 10mins to optimum frequency and power performance Steady State Current: (Vs = 12V, 25C ambient): 0.5A max Lock Monitor: Pin 2 is high (5V) when out of lock and low (0V) when locked Frequency Adjustment Pulling 5ppb min Control Voltage 0V to 5V Input Impedance 10k min Pulling is sufficent to allow 5ppb after the initial frequency offset is removed Control Voltage Input Current (Pin 1 swept from 0V to 5V): 40uA typ Control Voltage Input Capacitance (Pin 1): 5pF typ Note if no voltage is applied to the control voltage (pin1) it will be internally set to 2.5V. If a voltage is applied (even GND) to Pin 1, the oscillator will accept the external control voltage input.

Large copper plates should be avoided under the device, or mount the device with 1mm clearance from the PCB. Avoid airflow and do not attempt to mount heat sink to the device. The oscillator base plate runs hot: be aware that this may cause damage to other components in close proximity.
