SK1500
1:5 Signal Distribution
PPRREELLIIMMIINNAARRYY
The SK1500 is an extremely fast, stable, and accurate •
low skew 1:5 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 SK1500 uses standard open emitter ECL outputs
optimized for:
• General purpose ECL compatible applications
• Multiple destination applications (daisy
chain).
