INTRODUCTION
The MC145192EVK and MC145202EVK are two versions of one board with a few component changes.
They allow users to exercise features of both devices and to build PLLs which meet individual perfor-
mance requirements. The control program works with any board and can be used with other Motorola
PLL devices (MC145190, MC145191, MC145200, MC145201, MC145220*). It will select frequency de-
faults 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 dia-
gram 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.
