0x19: FOCCFG – Frequency Offset Compensation Configuration

Bit

Field Name

Reset

R/W

Description

7:6

Reserved

FOC_BS_CS_GATE

R/W

If set, the demodulator freezes the frequency offset

compensation and clock recovery feedback loops until the

CARRIER_SENSE signal goes high.

4:3

FOC_PRE_K[1:0]

2 (10)

R/W

The frequency compensation loop gain to be used before a sync

word is detected.

Setting

Freq. compensation loop gain before sync word

0 (00)

1 (01)

2 (10)

3 (11)

FOC_POST_K

R/W

The frequency compensation loop gain to be used after a sync

word is detected.

Setting

Freq. compensation loop gain after sync word

Same as FOC_PRE_K

K/2

1:0

FOC_LIMIT[1:0]

2 (10)

R/W

The saturation point for the frequency offset compensation

algorithm:

Setting

Saturation point (max compensated offset)

0 (00)

±0 (no frequency offset compensation)

1 (01)

±BWCHAN/8

2 (10)

±BWCHAN/4

3 (11)

±BWCHAN/2

Frequency offset compensation is not supported for OOK;

Always use FOC_LIMIT=0 with this modulation format.
