1.8 AUDIO CIRCUIT
[Outline]
A
(1) Analog Audio Signal
It converts the serial 3-wire digital output +DACCLK (audio clock) coming from DVD-LSI (IC1501) to
an Analog Audio Signal at Audio-DAC (IC1801) and output it from HOST IF connector (CN1901).
At the same time, it outputs an Analog MUTE Signal from DVD-LSI (IC1501) through HOST IF
connector (CN1901).
(2) Digital Audio Signal (IEC60958/IEC61937)
It outputs the Digital Audio Signal (IEC60958/IEC61937) coming from DVD-LSI (IC1501) through the
HOST IF connector (CN1952).
