MC100EL14

5V ECL 1:5 Clock

Distribution Chip

The MC100EL14 is a low skew 1:5 clock distribution chip designed

internally generated voltage supply, is available to this device only.

For single-ended input conditions, the unused differential input is

0.01

mF capacitor and limit current sourcing or sinking to 0.5 mA.

The EL14 features a multiplexed clock input to allow 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

pulldown resistor) the SEL pin will select the differential clock input.

The common enable (EN) is synchronous so that the 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.
