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

General Description

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.

Key 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 a.

Description 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 −2.375 V to −3.8 V (or 2.375 V to 3.8 V). 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.
