* The ’220 is not available in Rev. 2.5 software.

Most of these ICs are provided on an evaluation circuit board to allow the easy demonstration of the PLL
capabilities.

PURPOSE

The user guide for the MC145xxx PLL software familiarizes the user with the use and capabilities of the
program referred from here on as PLL Version 3.0. The guide covers the user interface and a summary
of the commands that are available.

The user should read the data sheet of the PLL frequency synthesizer of interest before using the soft-
ware.

DESCRIPTION

The PLL software:

•

is a Pascal program developed with Borland Turbo Pascal v7.0.

•

runs under MS–DOS.

•

is a character–based, menu–driven program.
