PL607041
ClockWorks® PCIe Quad Outputs
Ultra-Low Jitter, HCSL Frequency
Synthesizer
General Description
The PL607041 is a member of the ClockWorks® family of
devices from Micrel and provides an extremely low-noise
Spread-Spectrum clock for PCI Express requirements.
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 PL607041 accepts a
25MHz crystal.
Datasheets and support documentation are available on
Micrelâs web site at: www.micrel.com.
