The U-series XO: Ultra low jitter,
high frequency oscillators

The U-series Crystal Oscillators have a ultra low phase jitter of 0.125 picosecond typical in the frequency range of 150MHz to 2.1GHz with LVPECL, LVDS an HCSL output. This makes the U-series XO excellent for Terabit Ethernet applications up to 400GbE (fiber networking, cloud and storage systems,…)
