OCXO   TCXO   VCSO   VCXO   STD XO   Frequency Translation

Our precision quartz-based (phase-locked loops) products deliver low jitter timing distribution in support of the ITU G.8262 standard for Synchronous Ethernet. Many of our Frequency Translation products combine inherent high Q quartz-based oscillators with advanced performance PLL designs that enable communications customers to bridge high quality clock synchronization to the Ethernet.

Enhanced Clock Stability for the 1588 enabled network
