Clocks

Silicon Labs clocks generate any combination of output frequencies from any input frequency, simplifying clock synthesis and minimizing the number of timing components needed in a design. These clocks provide industry-leading jitter performance and functional integration and can be customized for any application. Silicon Labs also offers innovative PCI Express and LVCMOS clocks that simplify design and minimize power consumption in cost-sensitive applications.
