DISTRIBUTION

IC 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. If a single-ended

input is to be used the V

to the CLK input and bypassed to ground via a 0.01 F

capacitor. The V

switching reference for the input of the EL15 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.
