Table 27. BANDWIDTH - data byte 00h bit description
Bit Symbol Description
7 DYN dynamic bandwidth; see
Table 28
0 = FM IF bandwidth set by BW
1 = FM IF bandwidth dynamically controlled
6 to 2 BW[4:0] FM IF bandwidth; see
Table 28
DYN = 0
00h to 1Fh = FM fixed IF bandwidth 57 kHz to 165 kHz
DYN = 1
00h to 0Fh = minimum dynamic bandwidth 57 kHz to 109 kHz
10h to 1Fh = maximum dynamic bandwidth 113 kHz to 165 kHz
1 and 0 TE[1:0] threshold extension
00 = no threshold extension
01 = threshold extension low
10 = threshold extension standard
11 = threshold extension high
