The SK1927 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 upredictable
output pulse. It is also capable of receiving inputs of
any technology or voltage level. The D - flip-flop is
triggered on the falling edge of the clock.
The SK1927 uses 50
outputs with source /sink
capability, and is optimized for:
High speed clock / data lines
that require translation
Point to point, double termination
applications
