Ultra-Low Jitter Crystal Oscillators

Our ultra-low jitter crystal oscillators (UX family) are specifically designed to achieve ultra-low jitter as low as sub 0.1ps.

This family is ideal for networking and server systems which need ultra-low jitter clock source for high-speed data transfer. This family provides not only the performance with a wide margin to system engineers for their designs but also options including various output logic and sizes.
