OCXO delivers ±0.2ppb up to 70°C

The model can also be specified to operate over a wider -30 to 75°C temperature range with only a minor drop in temperature stability performance at ±0.5ppb. Available over a frequency range from 10 to 40MHz, the device consumes a maximum of 7W during warm up time which takes three minutes. Frequencies are available up to 100MHz with a lower stability of ±10ppb over -30 to 75°C. Designed to operate from a 3.3V supply, the IQOV-164 is housed in an industry standard 5pin euro package measuring 36 x 27mm and 13.5mm high. Output can be specified as HCMOS, 15pF load or Sinewave, into 50Ohms load. Phase noise performance is -158dBc/Hz at 100kHz offset and the IQOV-164 can be specified with different frequency pulling options to offset the impact of ageing. Typical ageing is ±0.2ppb per day, ±10ppb per year depending on the required specification.
