Rubidium Clock Oscillator

Mon, 04/30/2001 - 6:15am
Temex Components announced the availability of the new miniature Rubidium Master Oscillator (RMO) series that takes 200 cc of space and is 40 mm tall. Temex Neuchatel Time (Switzerland) developed a process that allows for this reduction in size. This product has the identical pin-out and function as ultra stable double-oven oscillators, yet it provides better than twice the stability performance. Long term stability is specified at <1 × 10– 11/month with <5 × 10– 11/month typical. The RMO can be used to upgrade existing (OCXO) designs or in new synchronization applications. Standard frequencies are 5, 10, and 20 MHz. Others include 8.192 and 4.096 MHz for ISDN systems, 13 MHz for GSM base stations, and 10.23 MHz for GPS.

The RMO is PCB mountable and has a wide input voltage range of 11.2 V to 15.5 V for the 12 V version and 18 V to 32 V for the 24 V version. There is a 2-pin RS232 port for digital frequency adjustment and monitoring. The RMO exhibits a typical frequency stability change of ± 5 × 10– 11 over the temperature range of – 5 ° C to 55 ° C.
