FSK/OOK Description
RegOcp
(0x0B)
7-6
unused
r
0x00
unused
5
OcpOn
rw
0x01
Enables overload current protection (OCP) for the PA:
0  OCP disabled
1  OCP enabled
4-0
OcpTrim
rw
0x0b
Trimming of OCP current:
Imax = 45+5*OcpTrim [mA] if OcpTrim <= 15 (120 mA) /
Imax = -30+10*OcpTrim [mA] if 15 < OcpTrim <= 27 (130 to 240
mA)
Imax = 240mA for higher settings
Default Imax = 100mA
Registers for the Receiver
RegLna
(0x0C)
7-5
LnaGain
rw
0x01
LNA gain setting:
000  reserved
001  G1 = highest gain
010  G2 = highest gain
– 6 dB
011  G3 = highest gain
– 12 dB
100  G4 = highest gain
– 24 dB
101  G5 = highest gain
– 36 dB
110  G6 = highest gain
– 48 dB
111  reserved
Note:
Reading this address always returns the current LNA gain (which
may be different from what had been previously selected if AGC
is enabled.
4-3
