FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION:
The FCT3805 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 offers low capacitance inputs
with hysteresis.
The FCT3805 is designed for high speed clock distribution where signal
quality and skew are critical. The FCT3805 also allows single point-to-
point transmission line driving in applications such as address distribution,
where one signal must be distributed to multiple recievers with low skew
and high signal quality.
For more information on using the FCT3805 with two different input
frequencies on bank A and B, please see AN-236.
