Description
PL60708X
PCIe Octal, Ultra-Low Jitter, HCSL Frequency Synthesizer
General Description
The PL607081 and PL607082 are members of the PCI Express family of devices from Micrel and provide extremely low-noise spread-spectrum clocks for PCI Express requirements.
The devices operate from a 3.3V or 2.5V power supply and synthesize eight HCSL output clocks. The PL607081 synthesizes 25MHz, 100MHz, or 200MHz frequencies and the PL607082 synthesizes 25MHz, 125MHz, or 250MHz frequencies. The PL60708x devices accept a 25MHz crystal or LVCMOS reference clock.
Datasheets and support documentation are available on Micrel’s web site at: www.micrel.com.
