Clocks & timing

Optimize system-level performance with our clocks & timing devices

A broad portfolio of flexible devices to reduce jitter and simplify your design

Get the best performance in your design with our broad portfolio of low-jitter, easy-to-use clocks and timing devices. Our portfolio allows you to build your clock tree with simple, discrete devices or highly-integrated solutions to solve your system timing needs. Learn how our devices enable industry-leading performance in a variety of applications.

Clock buffers

Clock buffers with low additive jitter performance and output skew and a high operating temperature range for industry-standard output formats including LVCMOS, LVDS, LVPECL and HCSL.

RF PLLs & synthesizers

Wideband, low-phase noise, high-performance solutions for applications that need low-power RF signaling.

Clock jitter cleaners & synchronizers

Low-power network synchronizers and lowest jitter, JESD204B-compliant jitter cleaners with internal phased-locked loops (PLLs) to reduce phase noise or jitter in the system.

Clock generators

Flexible and easy-to-use high-performance single or multiple PLL solutions for clocking high-speed serial links including PCI Express (PCIe).


Standard and programmable oscillators with less than 100 fs RMS jitter in industry-standard packages.

RTCs & timers

Real-time clocks (RTCs) and timers for optimizing system power consumption with support for long-timer monitoring and accurate clocking.
