QUICK REFERENCE DATA
Notes
1.
The supply voltage for the analog audio part of the IC can be 5 V or 8 V. For a supply voltage of 5 V the maximum
signal amplitudes at in- and outputs are 1 V (RMS). For a supply voltage of 8 V the maximum amplitudes are
2 V (RMS).
The RGB inputs can also be used as YPbPr input. The selection is made via the I
2
C-bus. The YPbPr input sensitivity
is in accordance with the DVD player specification.
