IQRB-1 High-Performance Rubidium Oscillators

IQD Frequency Products' rubidium oscillators are used as time distribution services

Image of IQD Frequency Products IQRB-1 High Performance Rubidium OscillatorsThe IQD Frequency Products IQRB-1 high-performance rubidium oscillator offers stability around 1,000 times more accurate than a typical oven controlled crystal oscillator (OCXO). Based around an atomic clock, the IQRB-1 delivers an accuracy of ±0.05 ppb regardless of temperature fluctuations. The rubidium is housed in a 5-pin 51 mm square package making it compatible with many existing OCXO footprints while offering considerably improved performance. Operating at a standard frequency of 10 MHz, the IQRB-1 can accept supply voltages of between 12 V and 18 V. Power consumption is up to 6 W (maximum) with a warm-up time of typically 5 minutes, again making it comparable with many OCXOs. The device can be operated over an operating temperature range of -30°C to +65°C and mean time between failure (MTBF) is approximately 100,000 hours. Storage temperature is rated at -55°C to +85°C and it is EMI compliant to FCC Part 15, Class B. Shock and Vibration performance is GR-CORE-63, 4.5.2/4, locked to 1.0 G. Standard output compatibility is sinewave, and it has 100 times less drift than typical OCXOs and short-term stability of ±0.008 ppb over a 1 second period.

The IQRB-1 can be used as a free run frequency source in applications such as long term evolution (LTE) systems that require exceptional timing accuracy. It can also be used for UTMS as well as extended holdover for CDMA and WiMax.
