The SK1925 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 SK1925 has open emitter PECL outputs.
Target applications:
High speed clock / data lines
that require translation
Multiple destination (daisy chain)
applications
