1. Description
2. Features
The PCKEL14 is a low skew 1:5 clock 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
PCKEL14 is designed to operate in ECL or PECL mode for a voltage supply range of
The PCKEL14 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 pull-down 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.
