TABLE 26. LOOK-UP TABLE REAL DATA
TYPE: PRE-DISTORTER, ADDRESS 0x17
BIT
FUNCTION
DESCRIPTION
15:0
LUT Data I
Real distortion data written to or read back from LUT. Selectable as (-0.5...(0.5-increment)) in increments
of 2
-16
. Default = 0.
TABLE 27. MEMORY EFFECT CONTROL
TYPE: PRE-DISTORTER, ADDRESS: 0x18
BIT
FUNCTION
DESCRIPTION
15:13
Reserved
Not used.
12
Serial Output Enable
Set to high to enable the external serial interface output pins. Default is low, disabled.
11:9
Reserved
Not used
8
Serial Input Enable
Set to high to enable the external serial interface input pin SERIN data to override the processor settings.
Default is low, disabled, processor settings over-ride serial inputs.
7:6
Reserved
Not used.
5:4
Power Integrator Period
Select the number of samples in the power integrate/dump operation. Also controls the SERCLK
frequency.
00 - 128 samples, SERCLK runs at CLK/4.
01 - 64 samples, SERCLK runs at CLK/2.
10 - 32 samples, SERCLK runs at CLK.
3:1
Reserved
Not used.
0
Thermal Coefficient B
Set to high to select A
2
, low to select B (default).
TABLE 28. MEMORY EFFECT COEFFICIENT A
TYPE: PRE-DISTORTER, ADDRESS: 0x19
BIT
FUNCTION
DESCRIPTION
15:0
Thermal Coef. A
Coefficient A for memory effect selectable from (-1.0...(1-increment)) in increments of 2
-15
. If control word
0x18, bit 8 high, reading this control word returns the value from SERIN.
TABLE 29. MEMORY EFFECT COEFFICIENT B
TYPE: PRE-DISTORTER, ADDRESS: 0x1a
BIT
FUNCTION
DESCRIPTION
15:0
Thermal Coef. B
Coefficient B for memory effect selectable from (-1.0...(1-increment)) in increments of 2
-15
. If control word
0x18, bit 8 high, reading this control word returns the value from SERIN.
TABLE 30. MEMORY EFFECT POWER INTEGRATOR LSW
TYPE: PRE-DISTORTER, ADDRESS: 0x1b
BIT
FUNCTION
DESCRIPTION
15:0
Power Integrator <15:0>
Power integrator LSW.
TABLE 31. MEMORY EFFECT POWER INTEGRATOR MSW
TYPE: PRE-DISTORTER, ADDRESS: 0x1c
BIT
FUNCTION
DESCRIPTION
15:0
Power Integrator <31:16> Power integrator MSW. The Power Integrator [31:0] forms an unsigned fixed point number with 9 integer
and 23 fractional bits (u9.23).
