Fox Electronics Introduces New OCXO for WiMAX Base Station Applications

June 6, 2007

Fox Electronics, a global supplier of frequency control products, announced a new HCMOS, 14-pin DIP oven controlled crystal oscillator (OCXO). Designed for use in base stations, the new FTS310 OCXO will benefit the WiMAX, HIPERMAN and WiBro markets in the US, Europe and Korea, respectively.


Fox’s new OCXO is more robust than TCXO options, clearly meeting the IEEE 802.16-2004 specification that dictates the OCXO have a frequency stability better than 8 PPM for 10 years. In addition, Fox’s new OCXO has a phase noise of -125 dBc/Hz at an offset of 100 Hz and of -145 dBc/Hz at an offset of 10 kHz.

The operating temperature for the FTS310 is -40° to +65°C, with an option of -40° to +85°C for use in outdoor units or locations requiring tolerance to higher temperatures. The new OCXO has a frequency range of 2.43 to 60.00 MHz, warms up to within ±4.6 PPM in two minutes and needs less than 1.5 W of power to do so. Its supply voltage is 3.30 V ±0.16 V, its operating power is 1.0 W at 0°C and 0.6 W at 25°C and its output load is 15 pF. The OCXO measures 20.8 L x 13.2 W x 11.0 mm H.

Pricing for a FTS310 OCXO is $17.00 each in quantities of 5,000. Delivery is eight weeks ARO.
