DESCRIPTION:
The FCT3805/A is a 3.3 volt, non-inverting clock driver built
using advanced dual metal CMOS technology. The device
consists of two banks of drivers, each with a 1:5 fanout and its
own output enable control. The device has a "heartbeat"
monitor for diagnostics and PLL driving. The MON output is
identical to all other outputs and complies with the output
specifications in this document. The FCT3805/A offers low
capacitance inputs with hysteresis.
The FCT3805/A is designed for high speed clock distribu-
tion where signal quality and skew are critical. The FCT 3805
also allows single point-to-point transmission line driving in
applications such as address distribution, where one signal
must be distributed to multiple receivers with low skew and
high signal quality.
