1:5/1:7 3.3V CMOS Clock Drivers

Description

Pericom Semiconductor’s PI49FCT3280x is a 3.3V very low-skew

clock buffer from a single low-capacitance input that produces ﬁve

outputs on PI49FCT32802 and seven outputs on PI49FCT32803.

Excellent output signals to power and ground ratio minimize power

and ground noise, and also improves output performance.

The PI49FCT3280x integrates series damping resistors on all

outputs.
