Inversion of Rx output data:
Baseband filter bandwidth calibration as a function of selected
Selection of the value of the shunt resistor across ports TKA
1010 -> 3.79 kΩ
1100 -> 6.04 kΩ
1110 -> 2.81 kΩ
Konnex mode:
Description
CLKOUT frequency (if enabled)
00 -> 1.22 MHz (div ratio :32)
01 -> 2.44 MHz (div ratio :16)
10 -> 4.87 MHz (div ratio :8)
11 -> 9.75 MHz (div ratio :4)
0 -> disabled
1 -> enabled
Baseband filter bandwidth calibration:
0 -> enabled
1 -> disabled
Period of baseband filter bandwidth calibration whilst Rx
enabled:
0 -> only at start-up of the receiver
1 -> 60 seconds (default mode) or 7 seconds (test mode)
bandwidth:
0 -> calibration restarted each time the bandwidth is changed
1 -> no calibration when the bandwidth is changed
Selection of the XOSC load capacitance mode:
0 -> CL+C0 = 15 pF
1 -> CL+C0 = 11 pF, low current mode
and TKB for a third overtone XTAL operation:
0000 -> 3800 kΩ
0010 -> 4.65 kΩ
0100 -> 8.79 kΩ
0110 -> 3.22 kΩ
1000 -> 16.55 kΩ
0 -> disabled
1 -> enabled
Enable programming of the sync and acquisition thresholds:
0 -> threshold are hard-coded and sync-loss counter is 50 bits
1 -> threshold are defined by BParam_Sync_thres and
BParam_Trac_thres
Sync loss counter is variable and defined by
ADParam_Sync_loss
Barker mode sync acquisition threshold
DATA port bidirectional mode:
0 -> enabled
1 -> disabled: DATA = output, DATAIN = input
Threshold for tracking Barker mode

0001 -> 2.55 kΩ
0011 -> 1.78 kΩ
0101 -> 2.07 kΩ
0111 -> 1.56 kΩ
1001 -> 2.26 kΩ
1011 -> 1.66 kΩ
1101 -> 1.91 kΩ
1111 -> 1.48 kΩ
