IQD's Launches New ±0.2ppb OCXO at IMS 2014

IQD’s new IQOV-164 series oven controlled crystal oscillator (OCXO) delivers exceptional frequency stability performance at ±0.2ppb over an operating temperature range of -20 to 70 degrees C. This new ultra high stability model can also be specified to operate over a wider -30 to 75 degrees C temperature range with only a minor drop in temperature stability performance at ±0.5ppb.

Available over a frequency range from 10 to 40MHz, this OCXO consumes a maximum of 7.0 Watts during warm up time which takes only 3 minutes. Frequencies are available up to 100MHz with a lower stability of ±10ppb over -30 to 75 degrees C. Designed to operate from a 3.3V supply, the IQOV-164 is housed in an industry standard 5-pin euro package measuring 36 x 27mm and 13.5mm high.

Output can be specified as either HCMOS, 15pF load or Sinewave, into 50 Ohms load. Phase noise performance is typically -158dBc/Hz at 100kHz offset and the IQOV-164 can be specified with different frequency pulling options in order to offset the impact of ageing. Typically ageing is ±0.2ppb per day, ±10ppb per year depending on the required specification.

With the IQOV-164 offering such exceptional frequency temperature stability combined with a short term stability of 1E-11/S it is particularly suitable for a range of applications including: 4G and LTE base stations, test & measurement, GPS, radar, communications, point to point communications and Sonet/SDH.

This new series forms part of an extensive range of OCXO’s available from IQD, which include extremely low phase noise performance and ultra small packages. Further information and the full data sheet is available at www.iqdfrequencyproducts.com.
