PI49FCT32807 3.3V 1:10 CMOS Clock Driv er Features Description Low skew: < 200ps Pericom Semiconductors PI49FCT32807 is a 3.3V very low- skew clock buffer that produces ten outputs from a single low- Fast switching frequency >133 MHz capacitance input. Excellent output signals to power and ground Fast output rise/fall time < 1.5ns ratio minimize power and ground noise, and also improves output Low propagation delay < 2.5ns performance. Low input capacitance < 6.0pF The PI49FCT32807 integrates series damping resistors on all 5V I/O Tolerant input outputs.
