DESCRIPTION:
The FCT20805 is a 2.5 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
and complies with the output specifications in this document. The FCT20805
offers low capacitance inputs.
The FCT20805 is designed for high speed clock distribution where signal
quality and skew are critical. The FCT20805 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.
