PROGRAMMABLE DIVIDER SETTING (BYTES DB1 AND DB2)
Divider ratio:
N = FOSC/Fss
where FOSC = ( FRF + FIF ) and Fss is the step-size set by RSA and RSB as described below.
N = 8192*N13 + 4096*N12 + 2048*N11 + 1024*N10 + 512*N9 + 256*N8 +
128*N7 + 64*N6 + 32*N5 + 16*N4 + 8*N3 + 4*N2 + 2*N1 + N0
Note: FIF = 36.15 MHz
CONTROL BYTE CB
Charge Pump Setting:
CP can be set to either 0 (low current) or 1 (high current).
CP = 1, charge pump current = 280uA results in fastest tuning (default mode)
CP = 0 , charge pump current = 60uA results in moderate speed tuning with better residual oscillator
PLL Disabling:
OS=0 for normal operation,
OS=1 switches off the PLL tuning amplifier (PLL tuning is disabled)
Weak Signal Booster:
Warning: WSB must be set to 0. Otherwise tuner overload will occur.
