(14)Dedicated VDD and GND signals
Signal Name
Function
V
DD
P
This is the dedicated V
DD
for the PLL unit.
GNDP
This is the dedicated GND for the PLL unit.
CV
DD
This is the dedicated V
DD
for the oscillator.
CGND
This is the dedicated GND for the oscillator.
DV
DD
This is the dedicated V
DD
for the D/A converter.
The voltage applied to this pin becomes the maximum value for AUDIOOUT’s analog output.
DGND
This is the dedicated GND for the D/A converter.
The voltage applied to this pin becomes the minimum value for AUDIOOUT’s analog output.
AV
DD
This is the dedicated V
DD
for the A/D converter.
The voltage applied to this pin becomes the maximum voltage value for the AD interface signal.
AGND
This is the dedicated GND for the A/D converter.
The voltage applied to this pin becomes the minimum voltage value detectable by the AD interface
signals.
PIUV
DD
This is the dedicated V
DD
for the touch panel interface.
PIUGND
This is the dedicated GND for the touch panel interface.
