3V Fast CMOS Clock Driver Description Pericom Semiconductor'
s PI49FCT3807 is a 3.3V 1-to-10 clock driver.Thislowskewclockdriverfeaturesoneinputandtenoutputs fanout. The large fanout from a single input line reduced loading on input clock. TTL level outputs reduce noise levels on the part. Typical applications are clock and signal distributon Pin Con?guration Pin Description Pin Name Description A Input B0-B9 Outputs GND Ground VCC Power Block Diagram PI49FCT3807 Features ? 3.3V version of PI49FCT807 ? Ultra low skew: 0.35ns ? Low Input Capacitance ? Minimum duty cycle distortion ? 1:10 fanout ? High speed: 3.5ns propogation ?

Note: Stresses greater than those listed under MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this speci?cation is not implied. Exposure to absolute maximum rating condi- tions for extended periods may affect reliability.
