MCCNFG/Win
Introduction
MCCNFG/Win is a 32 bit Windows application that will program the MC145170.
Because MCCNFG/Win is a 32 bit application it will run only with Windows 95, 98 and NT. MCCNFG/Win will not run with Windows versions 3.x.
MCCNFG/Win gives you full control over the C, R and N registers of the PLL so it should be usable will all MC145170 installations with a little experimentation... particularly in the C values. I suggest you obtain the Motorola MC145170 data sheet for a full description of the options that appear on the MCCNFG/Win configuration page.
Installing MCCNFG/Win
MCCNFG/Win accesses the LPT1 port on your PC to program the PLL.
MCCNFG/Win relies on NTPORT from Upper Canada Technologies to allow access to the port hardware under all supported versions of Windows. You can obtain NTPORT at Upper Canada Technologies web site. Please remember to register NTPORT as it is not freeware.
MCCNFG/Win is supplied as a ZIP file. To install do the following:
Configuring MCCNFG/Win for your PLL
When MCCNFG/Win is started you will see a screen similar to:
Select Configure from the File menu to open the configuration form. You will see a screen similar to:
Configuration options with the recommended values for the EXP-1 are as follows:
Option | EXP-1 | Register | Note |
Phase Detector Output Polarity | Off | C | Not Inverted |
Phase Detector A/B Selection | On | C | Phase Detector B |
Lock Detect Output | Off | C | Disabled |
REFout Frequency | Off | C | Static Low |
fVE Output | Off | C | Disabled |
fR Output | Off | C | Disabled |
PLL Reference Oscillator Frequency | 10000000 | R | hz |
PLL Tuning Step | 5000 | R | hz |
Display/Programmed Freq Difference | -10000 | hz | |
Minimum Input Frequency | 144000000 | hz | |
Maximum Input Frequency | 148000000 | hz | |

Notes:
Set the configuration options as accurately as possible and click OK to close the configuration form and save the options.
When back at the main screen enter the frequency you want to program into the PLL.
