PI49FCT32802 PI49FCT32803 1:5/1:7 3.3V CMOS Clock Drivers Features Description * * * * * * * * * * Pericom Semiconductor's PI49FCT3280x is a 3.3V very low-skew clock buffer from a single low-capacitance input that produces five outputs on PI49FCT32802 and seven outputs on PI49FCT32803. Excellent output signals to power and ground ratio minimize power and ground noise, and also improves output performance. Low skew: < 200ps Fast switching frequency >133 MHz Fast output rise/fall time < 1.5ns Low propagation delay < 2.5ns Low input capacitance < 6.0pF 5V Tolerant input Rail-to-Rail CMOS outputs Industrial Temperature: -40C to +85C 3.3V 10% operation Packages (Pb-free & Green available): - 16-pin 150-mil wide QSOP (Q) - 16-pin 173-mil wide TSSOP (L) The PI49FCT3280x integrates series damping resistors on all outputs.

For user guidelines, not tested.) 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 specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
