General Description

The PL602041 is a member of the ClockWorks

 family of

devices from Micrel and provides an extremely low-noise

timing solution for PCI Express clock signals.

The device operates from a 3.3V or 2.5V power supply

and synthesizes four HCSL output clocks at 25MHz,

100MHz, 125MHz, and 200MHz. The PL602041 accepts a

25MHz crystal.

Datasheets and support documentation are available on

Micrel’s web site at: www.micrel.com.
