PI49FCT32802 PI49FCT32803 1:5/1:7 3.3V CMOS Clock Drivers Features Description Low skew: < 200ps Pericom Semiconductors PI49FCT3280x is a 3.3V very low-skew clock buffer from a single low-capacitance input that produces ve Fast switching frequency >133 MHz outputs on PI49FCT32802 and seven outputs on PI49FCT32803. Fast output rise/fall time < 1.5ns Excellent output signals to power and ground ratio minimize power Low propagation delay < 2.5ns and ground noise, and also improves output performance. Low input capacitance < 6.0pF The PI49FCT3280x integrates series damping resistors on all 5V Tolerant input outputs.
