Product 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 to I
appropriate I
The TDA9989 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. The TDA9989 has
a very low power consumption, which is suitable for portable applications.
