OCXO boasts ±5ppb stability over –40 to 85°C
The IQOV-162 series, a minature OCXO from IQD, delivers a frequency stability down to ±5ppb over the full industrial temperature range from –40 to 85°C. Measuring 4 x 9.0mm, with a height of 6.5mm, the OCXO model is available in a wide frequency range from 10 to 100MHz.
Operating from a 3.3V supply voltage, the IQOV-162 consumes 600mA of current during warm up and takes less than 5 minutes to be within <100ppb of the final specification and 300mA max at a 25°C steady state. The output can be specified as either HCMOS, 15pF load or Sinewave, into a 50Ω load. As well as offering phase noise performance better than -150dBc/Hz at 1kHz offset, ageing performance is also extremely good at less than ±500ppb per year.
Variants can be specified to include voltage control to enable the frequency to be adjusted for correction over time and remotely with a pullability range of ±3ppm to ±8ppm. The IQOV-162 series is primarily designed to be used in applications such as CDMA base stations, femtocells, optical networking, 3G & 4G LTE, Ethernet, SoNET/SDH, ATM backplanes, SATA and satellite communications, or whenever a very low profile OCXO is required.
