1:9 Signal Distribution

PRELIMINARY

HIGH-PERꢀORMANCE PRODUCTS

Description

ꢀeatures

The SK1900 is an extremely fast, stable, and accurate

low skew 1:9 clock / signal distributor featuring a

synchronous enable, which allows the outputs to be

turned off and on without the risk of an unpredictable

output pulse. The D - flip-flop is triggered on the falling

edge of the clock.
