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: –40°C to +85°C 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.
