FSK/OOK Description
r 0x00 unused
Enables overload current protection (OCP) for the PA:
rw 0x01 0 Ã OCP disabled
1 Ã OCP enabled
Trimming of OCP current:
Imax = 45+5*OcpTrim [mA] if OcpTrim <= 15 (120 mA) /
rw
0x0b
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
LNA gain setting:
000 Ã reserved
001 Ã G1 = highest gain
010 Ã G2 = highest gain â 6 dB
011 Ã G3 = highest gain â 12 dB
100 Ã G4 = highest gain â 24 dB
rw 0x01 101 Ã G5 = highest gain â 36 dB
110 Ã G6 = highest gain â 48 dB
111 Ã 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.
Low Frequency (RFI_LF) LNA current adjustment
rw 0x00 00 Ã Default LNA current
Other à Reserved
rw 0x00 reserved
High Frequency (RFI_HF) LNA current adjustment
rw 0x00 00 Ã Default LNA current
