fREF = 1KHz
FVCO = (64
PC + SC + 64) fREF
AM SWALLOW MODE
FVCO = (DIV_VAL+ 64)
fREF
swallow 6bit
fREF = 2.5KHz
FVCO = (32
PC + SC + 32) fREF
FVCO = (DIV_VAL+ 32)
fREF
swallow 5bit (bit SC5 = 0)
AM DIRECT MODE
FVCO = (DIV_VAL+ 1)
fREF
a) CONDITIONS:
FM MODE (fRF = 98.1MHz, fREF = 25KHz; IF = 10.7MHz
it follows: that FVCO = 98.1 + 10.7 = 108.8MHz
DIV_VAL =

b) CONDITIONS:
FM MODE (fRF = 98.8MHz, fREF = 25KHz; IF = 10.7MHz
it follows: FVCO = 98.8 + 10.7 = 109.5MHz
DIV_VAL = 4380 - 32 = 4348 = 10 FC Hex
