Description
Linearity/sensitivity mode
Size of the reference Pattern:
(about 400 kHz SSB) and disables calibration:
0 -> bandwidth defined by BW(1:0)
1 -> bandwidth forced to its maximal value
Calibration of the bandwidth of the base band filter:
00 -> calibration at start up
01 -> no calibration
10 -> calibration when the bandwidth of the base band filter changes
11 -> calibration is forced each time 11 is written
Base band filter initialization:
00 -> default initialize at start up
01 -> RESERVED
10 -> initialize each time the bandwidth change
11 -> force re-initialization
RSSI off/on:
0 -> off
1 -> on
Range of the RSSI:
0 -> low range
1 -> high range
00 -> input power ≤ VTHR1
01 -> VTHR1 ≤ input power ≤ VTHR2
10 -> VTHR2 ≤ input power ≤ VTHR3
11 -> VTHR3 ≤ input power
Frequency Error Indicator off/on:
0 -> off
1 -> on
0 -> AFC not running process
1 -> AFC running
Writing 0 will start the AFC process. At the end of the AFC process, the
bit goes automatically back low.
Result of the AFC
0 -> AFC operation successful
1 -> AFC operation unsuccessful
Disabling the AFC
0 -> the error cancelation is automatically applied on the LO frequency
1 -> the error cancelation is not applied on the LO frequency
AFC overflow indicator
0 -> no overflow
1 -> the integrator of the frequency error is too high
writing 1 to this bit will reset the integrator
IQ amplifier off/on:
0 -> off
1 -> on
0 -> Mode A (high sensitivity)
1 -> Mode B (high linearity)
Pattern recognition off/on:
0 -> off
1 -> on
00 -> 8 bits
01 -> 16 bits
10 -> 24 bits
11 -> 32 bits
