Stable, low phase noise OCXO targets high performance comms

IQD has introduced a tight stability, low phase noise oven controlled crystal oscillator (OCXO) delivering frequency stability performance down to ±1ppb over the industrial temperature range of -40 to 85 degrees C.

The IQOV-114 has phase noise of typically -120dBC/Hz at 10Hz and -155dBc/Hz at 10kHz. The OCXO is therefore suitable for Stratum 3, 4G, LTE and 5G basestations, broadcast, Ethernet, satellite communications, Sonet or SDH, radar and wi-max applications.

The frequency range of the IQOV-114 is 8.192 to 30.72MHz and the currently developed frequencies are: 8.192, 10.0, 12.8, 13.0, 15.36, 16.384, 19.2, 20.0 and 30.72.0MHz. Ageing performance is less than ±0.5ppb per day and ±50ppb per year. Supply voltage variation is ±2ppb max and short term stability or Allan Variance (temperature stable, no EMI/EMC or other interference, test after power for 1hr ref. to 25 degrees C; 1s) is 0.01ppb max.

Packaged in a 20 x 12.7mm industry standard six-pad surface mount package with a FR4 base and metal lid, the HCMOS-based IQOV-114 OCXO is capable of driving up to 15pF loads and can operate at 3.3V, consuming a maximum of 1000mA during warm up and 500mA maximum at steady state at 25 degrees C.
