TDA523x
Functional Description
LIMC0: Trim RSSI Gain
ADDR: 0x1B
Reset Value: 0x0C
Bit R/W Description
4:0 W LIMGAIN: Trim the RSSI Gain (Slope)
Min: 00h = Minimum gain
Max: 1Fh = Maximum gain
IAF TDA523x Config Tool sets this value to 00h by default
LIMC1: Trim RSSI Offset, enable RSSI pin
ADDR: 0x1C
Reset Value: 0x15
Bit R/W Description
6:5 W RSSIMTR: Select signal for RSSI pin
00b: RSSI+
01b: RSSI- (reference)
10b: REF+ (reference)
11b: REF- (reference)
4 W RSSIMONE: Enable buffer for RSSI pin
0: buffer off
1: buffer on
3:0 W LIMOFFS: Trim the RSSI Offset
Min: 0h = Minimum offset
Max: Fh= Maximum offset
IAF TDA523x Config Tool sets this value to 0h by default
Dual: ADIGRXC and BDIGRXC: Global Settings
ADDR: 0x6C and 0x8C
Reset Value: 0x00
Bit R/W Description
2:1 W AAFILT: Anti Aliasing Filter
00b: 40 kHz use for data rates >9.6 kb/s
01b: 13.6 kHz use for data rates >3 kb/s
10b: 5 kHz use for data rates >2 kb/s
11b: 3.6 kHz use for data rates <=2 kb/s
The anti aliasing filter corner frequency can be changed to achieve better
performance. Note that the corner frequency and the data rate must be set
together.
This value is automatically created by the IAF TDA523x Config Tool
