SK1901
1:9 Signal Distribution
PRELIMINARY
The SK1901 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.
The SK1901 uses open emitter outputs with a double
amplitude swing suitable for the following applications:
• TTL compatible destinations
• Double termination situations that require
a full swing at the destination
• Long cables
