Output Voltage Swing vs. Frequency
In the divide-by-one mode, the output rise and fall times
will limit the peak-to-peak output voltage swing. For a
400 MHz output, the peak-to-peak swing of the SK12439
output will be approximately 700 mV. This swing will
gradually degrade as the output frequency increases; at
800 MHz, the output swing will be reduced to
approximately 500 mV. For a worst case analysis, it would
be safe to assume that the SK12439 output will always
generate at least a 400 mV output swing. Note that most
high-speed ECL receivers require only a few hundred
millivolt input swing for reliable operation. As a result, the
output generated by the SK12439 will, under all
conditions, be sufficient for clocking standard ECL devices.
Note that if a larger swing is desired, the SK12439 could
drive the clock fanout buffer SK100EP111.
