PI6C18551WEX

PI6C18551 3.3V/5V, 160 MHz, 4 output, CMOS Clock Buffer Features Description • • • • • • • PI6C18551 is a low skew, low noise and high-speed clock buffer for computing, networking and communication 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. 160 MHz 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) Pin Description Applications • • • • • 33 MHz for PCI 106.25 MHz for Fibre Channel 125 MHz for Ethernet 133 MHz for PCIX 155.52 MHz for OC3/SONET CLK_IN 1 8 OE* Y0 2 7 VDD Y1 3 6 GND Y2 4 5 Y3 *External pull-up recommended Logic Block Diagram Y0 Function Table Inputs Y1 Y2 CLK_IN Y3 OE 10-0157 Outputs CLK_IN OE Y[3:0] X L Z L H L H H H Note: 1.

External pull-up resistor is recommended. External Components A minimum number of external components are required for proper operation. 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 33-Ohm series terminating resistor may be used on each clock output if the trace is longer than 1 inch. An external 100k-Ohm pull-up resistor should be used on pin 8, OE.
