Table 25.
Table 26.
The following flowcharts describe how to:
The image rejection calibration and RF tracking filter calibration must be launched exactly
as described in the flowchart, otherwise bad calibration or even blocking of the
TDA18211HD can result making it impossible to communicate via the I
Proper internal initialization requires switching to Normal mode using a single I
sequence from subaddresses 03h to 0Fh.
This section provides instructions for reading the flowcharts.
