1-to-8 Minimum Skew Clock Driver
The CGS ’C/CT2525 is a minimum skew clock driver with
one input driving eight outputs specifically designed for sig-
nal generation and clock distribution applications. The ’2525
is designed to distribute a single clock to eight separate
receivers with low skew across all outputs during both the
t
PLH
and t
PHL
transitions. The ’2526 is similar to the ’2525
but contains a multiplexed clock input to allow for systems
with dual clock speeds or systems where a separate test
clock has been implemented.
