Iflna_res

Not used

lo_drive_reduced_current

iflna_pdet_lo

iflna_pdet_hi

h0000

Analog control signals.

Iflna_res (impedance)

settings:

0 = 10 kOhm

1 = 5 kOhm

2 = 3.3 kOhm

3 = 2.5kOhm

If the

lo_drive_reduced_current

is enabled the LO drive

current is reduced by

approximately 7mA.

The iflna_pdet_lo setting

generates the following

thresholds:

0 = 50 mV

1 = 100 mV

2 = 200 mV

3 = 400 mV

The iflna_pdet_hi setting

generates the following

thresholds:

0 = 200 mV

1 = 600 mV

2 = 1.0 V

3 = 1.2 V

Iflna_dccorr

iffilt_bp

iffilt_iqswap

h0000

Analog control signals.

Iflna_dccorr (dcofffset

correction) settings:

0 = 0 mV I channel diff.

offset

1 = 10 mV I channel diff.

offset

2 = 20 mV I channel diff.

offset

3 = 30 mV I channel diff.

offset

4 = -10 mV I channel diff.

offset

8 = -20 mV I channel diff.

offset

12 = -30 mV I channel diff.

offset

16 = 10 mV Q channel diff.

offset

32 = 20 mV Q channel diff.

offset

48 = 30 mV Q channel diff.

offset

64 = -10 mV Q channel

diff. offset

128 = -20 mV Q channel

diff. offset

192 = -30 mV Q channel

diff. offset

iffilt_bp changes the RX

filter from low-pass mode

to band-pass mode.

iffilt_iqswap swaps the I/Q

signals at the input of the

RX filter.

Bit 1 is affected by the

SKU setting.
