MC44BS373CA Data Sheet
High Speed I2C Compatible Bus
Figure 10. PLL Loop Filter
Loop filter equation:
ωo = 3-dB cutoff frequency
Kpd = 1-
A phase detector current
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
C2, added to minimize glitches, is usually set to one tenth the size of C1. For example:
Fref = 31.25 kHz
→ N = 5.5 MHz / 31.25 kHz = 176
Assuming C1 = 1
F, then
ωo = 168 rad, and Fo = 27 Hz
Q depends on the desired frequency response. Choosing Q = 0.7 as a starting point, then R = 8.5 K
. 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.
