N-divider fractional part bits 7:0 (out of 19:0). Writing this register also triggers VCO
autoselect (VAS).
N-divider fractional part bits 15:8 (out of 19:0)
Premixer gain configuration. Set to 1 for nominal gain. Set to 0 for approximately
2.5dB reduced gain.
0 = Selects RFINL input (for f
1 = Selects RFINH input (for f
0 = Disables RF LPF (for f
1 = Enables RF LPF (for f
0 = Sets IF BW to 7MHz mode
1 = Sets IF BW to 8MHz mode
Selects the tracking filter band of operation.
00 = VHFL (for f

IF output selection.
00 = IFOUT1 DTV differential mode (for driving a differential bandpass filter)
01 = IFOUT1 DTV single-ended (for driving a switched BW single-ended SAW filter)
10 = IFOUT2 ATV single-ended
11 = Unused
Programs series capacitor values in the tracking filter. The value is determined
from the values in the ROM table applied to an equation executed in the Maxim-
provided device driver code.
