Fox Electronics XpressO-TC oscillator

Fox Electronics has enhanced its XpressO line of low-jitter configurable oscillators with the XpressO-TC, a TCXO version with custom frequencies up to 250 MHz.

Part of the FXTC-HE73 series, the oscillator offers a tight frequency stability of ±2.5 ppm across an extended temperature range of -40 to 85°C. With custom frequencies up to 250 MHz, the oscillator offers an advantage over traditional TCXOs with a typical maximum frequency of 50 to 60 MHz.

The device is suitable for applications requiring high precision and low jitter, including medical monitoring and measurement, telecommunications and networking as well as military communications.

The product is based on the company’s 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.
