Based on atomic clock, IQRB-1 rubidium oscillator maintains high accuracy irrespective of temperature fluctuations. It operates at standard frequency of 10 MHz, accepts supply voltages between 12–18 V, and consumes up to 6 W with warm up time of typically 5 min. Operating temperature range is -30 to +65°C while storage temperature is rated at -55 to +85°C. Sub Miniature Atomic Clock is housed in 5-pin, 51 mm square package and resists EMI, shock, and vibration.
