PI49FCT3807
3.3V 1:10 CMOS Clock Driver
eatures
Description
Pericom Semiconductors PI49FCT series of logic circuits are
produced using the Companys advanced 0.5 micron CMOS
technology, achieving speeds up to 150 MHz, low-power dissipation,
and output skew less than 150ps.
The PI49FCT3807 is a 3.3V very low skew clock buffer that produces
ten outputs from a single low-capacitance input. Excellent output
signals to power and ground ratio minimize power and ground noise,
and also improves output performance.
Ultra low skew: <150ps
Fast switching frequency <150 MHz
Fast output rise/fall time <1.2ns
Low propagation delay <3.0ns
Low input capacitance <4.0pF
5V I/O Tolerant input
Rail-to-Rail CMOS outputs
Industrial Temperature: 40°C to +85°C
3.3V ±10% operation
Packages available:
20-pin 300-mil wide SOIC (S)
20-pin 150-mil wide QSOP (Q)
20-pin 209-mil wide SSOP (H)
