VIF high level
AFCWIN - AFC window (Note 1)
0
Tuning out of window (+/- 1.6 MHz)
1
Tuning in window (+/- 1.6 MHz)
Note1. If no IF input is applied, then bit AFCWIN = 1 due to the fact that the VCO is forced to the AFC window border for
fast load-in behaviour.
Automatic Frequency Control fVIF Versus f0
fVIF ≤ f0 – 187.5 kHz
fVIF = f0 – 162.5 kHz
fVIF = f0 – 137.5 kHz
fVIF = f0 – 112.5 kHz
fVIF = f0 – 87.5 kHz
fVIF = f0 – 62.5 kHz
fVIF = f0 – 37.5 kHz
fVIF = f0 – 12.5 kHz
fVIF = f0 + 12.5 kHz
fVIF = f0 + 37.5 kHz
fVIF = f0 + 62.5 kHz
fVIF = f0 + 87.5 kHz
fVIF = f0 + 112.5 kHz
fVIF = f0 + 137.5 kHz
