PI6C18551 Datasheet | Pericom Semiconductor

Features - - - - - - - 160MHz maximum frequency Low skew: 250ps Fast rise/fall time: 1.5ns Output Enable with tri-states Industrial Temperature 3.3V or 5V power supply Packaging (Pb-free & Green available): - 8-pin SOIC (W) Description PI6C18551 is a low skew, low noise and high-speed clock buffer for puting, networking and munication applications. It is a non-inverting buffer with four outputs from a single input. The outputs are controlled by output enable pin (OE), outputs are tri-states when OE is LOW, and outputs are enabled when OE is HIGH.

A decoupling capacitor of 0.01μF should be connected between VDD on pin 7 and GND on pin 6, as close to the device as possible. A 33Ω series terminating resistor may be used on each clock output if the trace is longer than 1 inch.
