DISTRIBUTION

chip designed explicitly for low skew clock distribution
applications. The device can be driven by either a
differential or single-ended ECL or, if positive power
supplies are used, PECL input signal. The EL14V is
suitable for operation in systems operating from 3.3V to
5.0V supplies. If a single-ended input is to be used the
V
bypassed to ground via a 0.01 F capacitor. The V
output is designed to act as the switching reference for
the input of the EL14V under single-ended input
conditions, as a result this pin can only source/sink up to
0.5mA of current.
for the distribution of a lower speed scan or test clock
along with the high speed system clock. When LOW (or
left open and pulled LOW by the input pull-down resistor)
the SEL pin will select the differential clock input.
outputs will only be enabled/disabled when they are
already in the LOW state. This avoids any chance of
generating a runt clock pulse when the device is enabled/
disabled as can happen with an asynchronous control.
The internal flip flop is clocked on the falling edge of the
input clock, therefore all associated specification limits
are referenced to the negative edge of the clock input.
