PI49FCT32807 3.3V 1:10 CMOS Clock Driver Features Description * * * * * * * * * * Pericom Semiconductor's PI49FCT32807 is a 3.3V very lowskew clock buffer that produces ten outputs from a single lowcapacitance input. 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 I/O Tolerant input Rail-to-Rail CMOS outputs Industrial Temperature: -40C to +85C 3.3V 10% operation Packaging (Pb-free & Green Available): - 20-pin 300-mil wide SOIC (S) - 20-pin 150-mil wide QSOP (Q) - 20-pin 209-mil wide SSOP (H) The PI49FCT32807 integrates series damping resistors on all outputs.
