FSK/OOK Description

RegOcp

(0x0B)

7-6

unused

0x00

unused

OcpOn

0x01

Enables overload current protection (OCP) for the PA:

0  OCP disabled

1  OCP enabled

4-0

OcpTrim

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

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

LnaBoostLf

0x00

Low Frequency (RFI_LF) LNA current adjustment

00  Default LNA current

Other  Reserved
