1.1GHz/500MHz DUAL PLL FREQUENCY SYNTHESIZER FOR DIGITAL CELLULAR PHONE
Note 6) Dividing ratio of the reference counter for reference frequency is given by 11-bit binary coads .
N(fREF1)=5~2047
Note 7) Dividing ratio N(VCO1) of VCO1 for local oscillator1 is given by 5-bit swallow counter and 12-bit
programable counter .
N(VCO1)=32 x M+A
(A<M)
M : Preset dividing ratio of 12-bit programmable counter (32~4095)
A : Preset dividing ratio of 5-bit swallow counter (0~31)
Note 8) Dividing ratio N(VCO2) of VCO2 for local oscillator2 is given by 4-bit swallow counter and 13-bit
programable counter .
N(VCO2)=16 x M+A
(A<M)
M : Preset dividing ratio of 13-bit programmable counter (16~38191)
A : Preset dividing ratio of 4-bit swallow counter (0~315)
