PL602082

PL60208X PCIe Octal, Ultra-Low Jitter, HCSL Frequency Synthesizer General Description The PL602081 and PL602082 are members of the PCI Express family of devices from Micrel and provide an extremely low-noise timing solution for PCI Express clock signals. They are based upon a unique synthesizer architecture that provides very low phase noise. The devices operate from a 3.3V or 2.5V power supply and synthesize eight HCSL output clocks. The PL602081 synthesizes 25MHz, 100MHz, or 200MHz and the PL602082 synthesizes 25MHz, 125MHz, or 250MHz. The PL60208x devices accept a 25MHz crystal or LVCMOS reference clock. Datasheets and support documentation are available on Micrel’s web site at: www.micrel.com.
