SK1502
1:5 Signal Distribution
PRELIMINARY
The SK1502 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 SK1502 uses 50Ω outputs with source /sink
capability, and is optimized for applications that require:
• Point to point, double terminated, timing
critical lines
