Loop filter equation:
C2, added to minimize glitches, is usually set to one tenth the size of C1. For example:
Q depends on the desired frequency response. Choosing Q = 0.7 as a starting point, then R = 8.5 KΩ. The
resistance acts directly on the factor quality and can be adjusted to create a peak on the low-frequency range.
It is recommended that the value of R be adjusted experimentally depending on the application and
requirements.

Kosc = 5 MHz/V sound oscillator slope. (In fact, Kosc = 40 MHz/prescaler divider = 8.) This
provides 5 MHz/V.
N = Sound divider ratio
Q = quality factorvR
Fref = 31.25 kHz → N = 5.5 MHz / 31.25 kHz = 176
