AGC_LNA_PRIORITY
1
R/W
Selects between two different strategies for LNA and LNA 2
gain adjustment. When 1, the LNA gain is decreased first.
When 0, the LNA 2 gain is decreased to minimum before
decreasing LNA gain.
5:4
CARRIER_SENSE_REL_THR[1:0]
0 (00)
R/W
Sets the relative change threshold for asserting carrier sense
Setting
Carrier sense relative threshold
0 (00)
Relative carrier sense threshold disabled
1 (01)
6 dB increase in RSSI value
2 (10)
10 dB increase in RSSI value
3 (11)
14 dB increase in RSSI value
3:0
CARRIER_SENSE_ABS_THR[3:0]
0 (0000)
R/W
Sets the absolute RSSI threshold for asserting carrier sense.
The 2-complement signed threshold is programmed in steps
of 1 dB and is relative to the MAGN_TARGET setting.
Setting
Carrier sense absolute threshold
(Equal to channel filter amplitude when AGC
has not decreased gain)
-8 (1000)
Absolute carrier sense threshold disabled
-7 (1001)
7 dB below MAGN_TARGET setting
-1 (1111)
1 dB below MAGN_TARGET setting
0 (0000)
At MAGN_TARGET setting
1 (0001)
1 dB above MAGN_TARGET setting
7 (0111)
7 dB above MAGN_TARGET setting
