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).

2. The RGB inputs can also be used as YPbPr input. The selection is made via the I2C-bus. The YPbPr input sensitivity

is in accordance with the DVD player specification.
