7. Appendix C: Application Information

7.1. Exclusions of Audio Baseband Features

In general, all functions can be switched independently.

Two exceptions exist:

1. NICAM cannot be processed simultaneously with

secondary channel (see Fig. 2–3 and Fig. 2–2 on

page 10).

2. FM adaptive deemphasis cannot be processed

simultaneously with FM-identification.

7.2. Phase Relationship of Analog Outputs

The analog output signals: Main, Aux, and SCART2 all

have the same phases. The SCART1 output has oppo-

site phase.

Using the I2S-outputs for other DSPs or D/A convert-

ers, care must be taken to adjust for the correct phase.
