−
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

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.
