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.
