1-TO-10 CLOCK DRIVER
DESCRIPTION:
The FCT3807 is a 3.3V clock driver built using advanced CMOS technol-
ogy. This low skew clock driver offers 1:10 fanout. The large fanout from a single
input reduces loading on the preceding driver and provides an efficient clock
distribution network. Multiple power and grounds reduce noise. Typical
applications are clock and signal distribution.

4. Propagation delay range indicated by Min. and Max. limit is due to V
CC
, operating temperature and process parameters. These propagation delay limits do not imply skew.
5. Skew measured between all outputs under identical transitions and load conditions.
6. Skew measured is difference between propagation delay times t

and t

of same output under identical load conditions.
7. Part to part skew for all outputs given identical transitions and load conditions at identical V
CC
levels and temperature.
8. Airflow of 1m/s is recommended for frequencies above 133MHz.
