Table 5-61. AFC Register (43h, Read Only)

DEFAULT

NAME

ACTIVE

DESCRIPTION

VALUE

AFC[7 :0]

AFC[7:0]

—

Average received frequency deviation from IF. This 8-bit 2-complement

signed value equals the demodulator decision level and can be used

for AFC.

The average frequency offset from the IF frequency is

ΔF = Baud rate × AFC / 16

DEFAULT

NAME

ACTIVE

DESCRIPTION

VALUE

GAUSS_FILTER[7 :0]

GAUSS_FILTER[7:0]

—

Readout of instantaneous IF frequency offset from nominal

IF. Signed 8-bit value.

ΔF = Baud rate × GAUSS_FILTER / 8
