17 APPLICATION INFORMATION
The application diagram (see Fig.19) must be considered as one of the examples of a (limited) application of the chip
e.g. in this case the I
2
S-bus inputs are not used. For the real application set-up the information of the application report
and application support by Philips are necessary on issues such as EMC, kappa reduction of the package,
DSP programming, etc.
