IQD targets high performance communications applications with new tight stability, low phase noise OCXO
IQD has introduced a new tight stability, low phase noise Oven Controlled Crystal Oscillator (OCXO) delivering exceptional frequency stability performance down to ±1ppb (parts per billion) over the full industrial temperature range of -40 to 85 degrees C.
With excellent phase noise of typically -120dBC/Hz @10Hz and -155dBc/Hz @10kHz, the IQOV-114 is the ideal choice for Stratum 3, 4G/LTE/5G Base Stations, Broadcast, Ethernet, Satellite Communications, Sonet/SDH, Radar and Wi-Max applications.
The frequency range of the IQOV-114 is 8.192 to 30.72MHz whilst the currently developed frequencies are: 8.192MHz, 10.0MHz, 12.80MHz, 13.0MHz, 15.36MHz, 16.384MHz, 19.2MHz, 20.0MHz and 30.72.0MHz. Ageing performance is extremely good at less than ±0.5ppb per day and ±50ppb per year. Supply Voltage Variation (measurement referenced to frequency observed with TA=25 degrees C, Vs varied from 3.13V to 3.47V and load=15pF) is ±2ppb max whilst 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, this HCMOS based 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 @25 degrees C.
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.
