This buffer/clock driver is built using advanced dual metal CMOS
technology. The FCT805T is a non-inverting clock driver consisting of two
banks of drivers. Each bank drives five output buffers from a standard TTL
compatible input. This part has extremely low output skew, pulse skew, and
package skew. The device has a “heart-beat” monitor for diagnostics and
PLL driving. The monitor output is identical to all other outputs and complies
with the output specifications in this document.
The FCT805T is designed for fast, clean edge rates to provide accurate
clock distribution in high speed systems.
