**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 Model IQRB-1 Model Issue number 2 ## **Frequency Parameters** - Frequency 10.0MHz - Frequency Tolerance ±0.05ppb - Tolerance Condition - @ 25°C - Frequency Stability ±0.50ppb - Operating Temperature Range -30.00 to 65.00°C - Short Term Stability (AVAR): 1s 0.08ppb 10s 0.03ppb 100s 0.008ppb ## **Outline (mm)** - Ageing: Day 0.005ppb Month 0.05ppb - Magnetic Field Sensitivity, DC (±2 Gauss): ±0.04ppb/Gauss max - Temperature Coefficient (ambient): 5x10ˉ¹º (0 to 50°C) - Retrace: ±0.02ppb max ## **Electrical Parameters** ## Supply Voltage ## 12.0V - ~~.~~ Note: The device will operate over the Supply Voltage Range 12V to 18V. - Input Power (@ 25°C): 6W @ 12V, 1.2A max. - Warm Up Time: 5mins to lock @ 25°C. - 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 10kΩ 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. ## **Output Details** Output Compatibility Sine Drive Capability 50Ω - Output Levels: 7dBm min, 9.5dBm typ, 13dBm max ## **Sales Office Contact Details:** UK: +44 (0)1460 270200 Germany: 0800 1808 443 France: 0800 901 383 USA: +1.760.318.2824 Email: info@iqdfrequencyproducts.com Web: www.iqdfrequencyproducts.com Page 1 of 2 Printed on 25 Sep 17 14:27 using Part Data Sheet V1.00015 **Rubidium Specification** _Part No. + Packaging:_ _**LFRBXO059244Bulk**_ ## **Noise Parameters** Phase Noise (typ): - -67dBc/Hz @ 1Hz - -95dBc/Hz @ 10Hz - -127dBc/Hz @ 100Hz - -140dBc/Hz @ 1kHz Harmonics: -40dBc max ## **Environmental Parameters** Storage Temperature Range: -55 to 85°C Base Plate Temperature: -30 to 85°C - Case Temperature (after 1hr, ambient temp 25°C, no ventilation): 45°C max - Mechanical Shock: IEC 60068-2-27, Test Ea: Acceleration of 50G peak amplitude for 11ms duration. Vibration: IEC 60068-2-06, Test Fc: 10Hz-55Hz 1.5mm displacement, 55Hz-500Hz 10G acceleration. Atmospheric Pressure: -60m to 4000m: 1x10ˉ¹³mbar max EMI: Compliant to FCC Part 15, Class B. ## **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 85°C depending upon environmental conditions. We recommend leaving about a 5mm minimum gap around the rubidium module wherever possible. ## **Compliance** RoHS Status (2011/65/EU) Compliant REACh Status Non-Compliant MSL Rating (JDEC-STD-033): Not Applicable ## **Packaging Details** Pack Style: Bulk Bulk pack Pack Size: 1 _Alternative packing option available_ ## **Technical Notes** _RoHS Compliance: 5/6_ ## **Sales Office Contact Details:** UK: +44 (0)1460 270200 Germany: 0800 1808 443 France: 0800 901 383 USA: +1.760.318.2824 Email: info@iqdfrequencyproducts.com Web: www.iqdfrequencyproducts.com Page 2 of 2 Printed on 25 Sep 17 14:27 using Part Data Sheet V1.00015
