TDA9989
HDMI 1.3a transmitter with CEC support
7.8.3 Audio port internal assignment
The aim of the internal audio input assignment is to internally map any of the incoming
data from the audio port AP1 to I2S-bus channel 0 or S/PDIF internal ports by setting the
appropriate I2C-bus register.
7.9 Power management
The TDA9989 HDMI and CEC cores can be independently powered down by the I2C-bus
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.
Table 17 gives the typical power consumption of the device in different congurations.
