FUNCTION
TUN[2:0]
7, 6, 5
011
Sets the IF filter center frequency. This filter’s center frequency is trimmed at the
factory, but can be manually adjusted by setting the FLTS bit and programming
the TUN[2:0] bits as follows:
000 - 0.75 x fIF (Not factory tested.)
001 - 0.84 x fIF (Not factory tested.)
010 - 0.92 x fIF (Not factory tested.)
011 - fIF (571kHz)
100 - 1.08 x fIF (Not factory tested.)
101 - 1.16 x fIF (Not factory tested.)
110 - 1.25 x fIF (Not factory tested.)
111 - 1.33 x fIF (Not factory tested.)
FLTS
4
0
Selects which registers set low-IF bandpass filter center frequency and
bandwidth.
0 = Selects internal factory set register.
1 = Selects manual trim register TUN[2:0] (Not factory tested).
IFL[1:0]
3, 2
01
Set the bias current for the low-IF circuits to provide for fine linearity adjustments.
Program to 01 upon power-up.
PDBW[1:0]
1, 0
11
Sets the IF power detector bandwidth.
00 = 43MHz bandwidth.
01 = 26MHz bandwidth.
10 = 17MHz bandwidth.
11 = 13MHz bandwidth.
