Input linearity performance degrades over frequency, see Figure 30 and Figure 31.

The D3/SEROUT pin is an input in parallel control mode and an output in serial control mode. See Table 5 for the pin function descriptions.

3

For power derating over frequency, see Figure 2 to Figure 3. Applicable for all ATTIN and ATTOUT power specifications.
