DESCRIPTION:
The FCT3805 is a 3.3 volt clock driver built using advanced 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
andcomplieswiththeoutputspecificationsinthisdocument. TheFCT3805offers
low capacitance inputs.
The FCT3805 is designed for high speed clock distribution where signal
quality and skew are critical. The FCT3805 also allows single point-to-point
transmissionlinedrivinginapplicationssuchasaddressdistribution,whereone
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.
