PLL Calculator (MC 145151-2)

The PLL Frequency Synthesizer Family encompasses devices that are used on a low-power phase-locked loop frequency and which are often used as an extension to the regular PLL synth that is operating on the frequency limit. These additional devices can provide all of the remaining functions for the said synth when situated at the frequency threshold.

In order for users to determine the reference oscillation and input frequency values used with MC145151-2 devices, specific calculus is required. This is exactly what PLL Calculator (MC 145151-2) was designed for.

It will offer an accessible way for determining the required oscillation and frequency values, based on range limits and increment. Users must be aware though, that handling the app will require a sound knowledge of the working principle behind PLL frequency synthesizers.

Basing its functionality around the specified input frequency and the added reference oscillator values, it will yield the divider values which are required for locking the PLL synth accordingly.

Three rates are available for the calculation, namely 1/64, 128 and 256 and users have the options to either copy the results as text strings or save them as images, into BMP format. The reference oscillator dividers and the input frequency dividers are individually selectable.
