This pin is main and standby supply for the analog
LVDS core.
VSUP3.3LVDS
− Supply Voltage 3.3 V
This pin is main and standby supply for the Digital
LVDS port.
VSUP3.3FL
− Supply Voltage 3.3 V
This pin is main and standby supply for the Flash
device.
VSUP3.3DRI
− Supply Voltage 3.3 V
This pin is main supply for the digital RAM interface.
VSUP3.3RAM
− Supply Voltage 3.3 V

ports and common digital logic.
VSUP3.3DIG
− Supply Voltage 3.3 V
This pin is main supply for the digital core logic of IF
and audio processing and digital video backend.
VSUP8.0AU
− Supply Voltage 8.0 V
This pin is main supply for the analog audio process-
ing.
VSUP5.0SIF
− Supply Voltage 5.0 V
This pin is main supply for the SIF processing.
VSUP3.3DAC
− Supply Voltage 3.3 V
This pin is main and standby supply for the Analog
DAC.
GND*
− Ground
This pin are main ground for all digital analog and port
supplies.
Application Note:
All GND pins must be connected to a low-resistive
ground plane underneath the IC. All supply pins must
be connected separately with short and low-resistive
lines to the power supply. Decoupling capacitors from
VSUPxx to GND have to be placed as closely as pos-
sible to these pins. It is recommended to use more
than one capacitor. By choosing different values, the
frequency range of active decoupling can be extended.
3.13.2.Audio Pins
VREFAU – Reference Voltage for Analog Audio
This pin serves as the internal ground connection for
the analog audio circuitry. It must be connected to the
GND pin with a 3.3
µF and a 100 nF capacitor in paral-
lel.
