Sequence For Enabling Clgc Tracking Calibration - Analog Devices ADRV9029 User Manual

SEQUENCE FOR ENABLING CLGC TRACKING CALIBRATION

Table 44. DPD Tracking Cal Bringup Sequence
Step Action
1 Program the device and run initial calibrations(including
TxQEC initial calibration) with the PA turned off.
2 Setup external Tx to ORx mapping
3 Adjust ORx gain to an appropriate value to avoid saturation.
The default gain index in ADRV9025 is 255 (0dB
attenuation)
4 Turn on the PA and run the external path delay initial
calibration.
5 Run the Tx external LO Leakage initial calibration
6 If using ADRV9025 CFR, configure the CFR settings.
7 If using ADRV9025 CFR, run the CFR initial calibration
8 Load the DPD model
9 Assert DPD Reset
10 Setup DPD mode of operation, DPD peak search window
size and low power threshold
11 Setup DPD fault conditions and recovery actions(optional)
12 Setup CLGC configurations and target loop gain
13 Enable Tx QEC and Tx LO Leakage tracking Calibrations
14 Enable DPD Tracking Calibration
15 Enable CLGC Tracking Calibration
16 Monitor DPD tracking calibration status
17 Monitor CLGC tracking calibration status
