Miniature OCXO from IQD delivers ±10ppb stability

IQD has released the IQOV-71 series, its latest Oven Controlled Crystal Oscillator (OCXO). The device is housed in 4-pad plastic package with a glass fibre base measuring 9.7 x 7.5mm. The device is said to offer frequency stabilities down to ±10ppb over an operating temperature range of -20 to 70°C or ±20ppb over -40 to 85°C.

Standard frequencies available are between 10 and 50MHz. Power consumption is claimed to be typically less than 1W during warm up which takes approximately 3 minutes and less than 0.4W once the device has reached steady state.

The IQOV-71 offers either a standard HCMOS or Clipped sinewave output, with operating voltages specified at either 3.3 or 5.0V. Low phase noise performance is assured with figures of -152dBC/Hz at 10kHz offset and -153dBc/Hz at 100kHz from the carrier. The device's G-sensitivity is <2ppb/G making the design suitable for applications such as military radios and airborne applications.

The IQOV-71 is intended for applications including Picocells in wireless applications, satellite communication, broadcasting, microwave and instrumentation such as frequency counters and analysers.
