FMZPLL_CALCULATOR

The FMzPLL Calculator assists a user with the configuration of the FMzPLL on TMS570 microcontrollers. It allows the user to input:

• OSCIN speed
• multiplier setting
• divider settings
• frequency modulation settings
• PLL/OSC fail options

Once the user has configured the desired options, the calculator displays the PLL output speed and the corresponding PLLCTL1 and PLLCTL2 register settings.

The tool also contains a reverse calculator mode that will display all PLL options when values for PLLCTL1 and PLLCTL2 are entered.
