INTRODUCTION
The MC145190EVK, '191EVK, '200EVK, and '201EVK are versions of one board with a few component
changes. They allow users to exercise features of the four devices and to build PLLs which meet individ-
ual performance requirements. The control program works with any board and can be used with other
Motorola PLL devices (MC145192, MC145202, MC145220*). It will select frequency defaults that apply
to each. All board functions are controlled through the printer port of an IBM PC. Up to three different
EVKs may be controlled at the same time from one printer port. The functional block diagram is given in
Figure 1.
This manual is divided into two sections. Section 1 describes the hardware and Section 2 covers the
software control program.
