Preliminary data sheet
7.8.3 Audio port internal assignment
7.9 Power management
The aim of the internal audio input assignment is to internally map any of the incoming
data from the audio port AP1 or AP2 to I
setting the appropriate I
TDA19989 HDMI and CEC cores can be independently powered down by the I
register. In Standby mode all activities are reduced by switching off all PLLs, HDMI and
CEC cores and disconnecting the biasing structure of the output stage. TDA19989 has a
very low power consumption, which is suitable for portable applications.
