Description
provides 16 MHz reference signal on the
XTOUT1, XTOUT2 pins.
XTOUT mode:
spreads digital clock power to improve
tuner EMC behavior
Description
sets the tuner desired IF frequency by
50 kHz steps. For example, to set the IF
frequency to 4 MHz, IF_Freq value must
be 4000/50 = 80.
sets the desired RF frequency expressed
in kHz
Description
these bits are used to control the
calibration and calculation automats
embedded in the chip and must be used
according to the programming flowchart
Figure 4
Description
