3.2x2.5mm oscillators provide Jitter under 1ps for industrial applications

April 11, 2012 // By Julien Happich
Fox Electronics has expanded its line of XpressO configurable crystal oscillators with an extended temperature version of its 3.3 V HCMOS oscillator in a compact 3.2x2.5mm package.

Part of the FXO-HC33 series, the new oscillator can withstand temperatures from -40 to +85°C, while delivering tight stabilities down to ±50 ppm. Typical uses of the new oscillator include SONET, Ethernet, broadband access and fiber channel as well as in test and measurement equipment. The frequency range for the new extended temperature XpressO oscillators is 0.75 MHz to 250 MHz with extremely low phase jitter down to 0.8 ps RMS, depending on the frequency.

The FXO-HC33 oscillators offer a 3.2x2.5x1.0mm with an industry standard footprint and pin-out. The RoHS and REACH compliant components use a gold over nickel termination finish. All XpressO oscillators incorporate a unique serial ID for each individual part that enables Fox to track product manufacturing from raw materials through final testing for increased quality control. XpressO oscillators use a proprietary ASIC family, developed by Fox, with a 3rd order Delta Sigma Modulator (DSM) to significantly reduce noise to levels comparable with traditional bulk quartz and SAW oscillators. The ASIC family enables the selection of output type, input voltages and temperature performance within the oscillator.
