New ultra miniature OCXO from IQD delivers ±5ppb stability in a 14 x 9mm package
Posted: 22nd April 2014
In an industry standard package measuring just 14 x 9.0mm and with a height of only 6.5mm, IQD’s new IQOV-162 series OCXO provides a frequency stability down to ±5ppb (parts per billion) over the full industrial temperature range from –40 to 85 degrees C.
In addition to this exceptional size/performance ratio the new model is available in a very 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 steady state @25 degrees C.
The output can be specified as either HCMOS, 15pF load or Sinewave, into a 50 Ohms load. As well as offering phase noise performance better than -150dBc/Hz @ 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.
