Fox's New XpressO TCXOs for Custom Frequencies
Highly stable TCXO.
Fort Myers, FL — Fox Electronics, an IDT company, has enhanced its innovative XpressO line of low jitter configurable oscillators with the XpressO-TC, a new TCXO (Temperature-Compensated Crystal Oscillator) version with custom frequencies up to 250MHz. As with all XpressO oscillators, the new TCXOs can be delivered in less than 10 working days, a major improvement over the standard lead times of competitive offerings.

Part of the FXTC-HE73 series, the new HCMOS XpressO-TC oscillators offer a tight frequency stability of ±2.5ppm across an extended temperature range of -40 to +85°C. With custom frequencies up to 250 MHz, the new TCXOs offer a significant advantage over traditional TCXOs with a typical maximum frequency of 50 to 60MHz. The new devices are suitable for applications requiring high precision and extremely low jitter, including medical monitoring and measurement, telecommunications and networking as well as military communications.

The XpressO-TC is based on the company's proprietary ASIC technology with a 3rd order Delta Sigma Modulator (DSM) to significantly reduce noise to levels comparable with traditional bulk quartz and SAW oscillators. This ASIC family enables the selection of output type, input voltages and temperature performance within the oscillator.
