PCKEL14 Datasheet (NXP Semiconductors) - 2.5 V/3.3 V PECL/ECL 1:5 clock distribution chip

PCKEL14, 2.5 V/3.3 V PECL/ECL 1:5 clock distribution chip

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

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
