TABLE 20. MAGNITUDE FUNCTION CONTROL
TYPE: PRE-DISTORTER, ADDRESS: 0x11
BIT
FUNCTION
DESCRIPTION

Not used
13:12
Magnitude Function
Select
Selects the magnitude calculation function as:
00 - Log. Log base 2 of magnitude squared computed as log2(I
2
+ Q
2
)
01 - Linear. Linear magnitude computed as sqrt (I
2
+ Q
2
)
10 - Power. Magnitude squared computed as (I
2
+ Q
2
)
11:0
Address Offset
Linear offset of magnitude function when calculating LUT address (e.g. power backoff) Selectable from
(-1024...1024) in increments of 2
-1
. Note: Setting the LSB of this value permits rounding of the resulting
address. Clearing the LSB causes truncation. (0xFFFFF --> 0x00000 maps to -1024 to 0, and 0x00001 -
-> 0x7FFFF maps to 0.5 to 1023.5).
TABLE 21. I - MAGNITUDE FUNCTION SCALE FACTOR
TYPE: PRE-DISTORTER, ADDRESS: 0x12
BIT
FUNCTION
DESCRIPTION
15:13
Reserved
Not Used.
12:0
Address Scale
Linear scale of magnitude function when calculating LUT address (e.g. db/LSB) Selectable from (0.(64-
increment)), in increments of 2
-7
.
TABLE 22. Q - LOOK-UP TABLE CONTROL
TYPE: PRE-DISTORTER, ADDRESS: 0x13
BIT
FUNCTION
DESCRIPTION
15:14
Reserved
Not Used.
13
Active LUT
Selects which ping pong LUT is currently in use. The opposite LUT shall be accessible through the
processor interface.
0 - Use LUT 0, access LUT 1.
1 - Use LUT 1, access LUT 0.
12
LUT Address Auto
Increment
Set high to automatically increment LUT address after any access operation (read/write). Default is low,
not auto increment.
11:10
Reserved
Not used.
9:0
LUT Address
Address for index into LUT. Default = 0, pointer to next LUT location.

TYPE: PRE-DISTORTER, ADDRESS: 0x14
BIT
FUNCTION
DESCRIPTION
15:14
Reserved
Not used.
13:0
LUT Data Delta Q
Delta imaginary Data written to or read back from LUT. Delta Q controls memory effect. Selectable as (-
0.125...(0.125-increment)) in increments of 2
-16
. Default = 0.

TYPE: PRE-DISTORTER, ADDRESS: 0x15
BIT
FUNCTION
DESCRIPTION
15:14
Reserved
Not used.
13:0
LUT Data Delta I
Delta real data written to or read back from LUT. Delta I controls memory effect. Selectable as (-
0.125...(0.125-increment)) in increments of 2
-16
. Default = 0.
TABLE 25. LOOK-UP TABLE IMAGINARY DATA
TYPE: PRE-DISTORTER, ADDRESS: 0x16
BIT
FUNCTION
DESCRIPTION
15:0
LUT Data Q
Imaginary distortion data written to or read back from LUT. Selectable as (-0.5...(0.5-increment)) in
increments of 2
-16
. Default = 0.
