Pin Description
RGB elementary color signal output pin. Can
be changed to VCC2/2 and VCC2*21/51 with
the serial bus.

SIGCENT
VCC2/2
Pin to set the DC voltage of R/G/B/COM/DSD
output. Connect a capacitor of 0.01μF
between this pin and GND2. When the signal
output DC voltage is to be used with the
setting other than VCC2/2 and VCC2*21/51,
set to the SIG center level changeover: high
voltage mode with the serial bus and apply the
voltage (3.3 - 3.7V) from the outside.

VCC1
3.0V
Analog 3V power supply.
50
DSDOUT
VCC2/2
Drain hold data power output pin. The output
VCC2*21/51 DC voltage can be set to VCC2/2 and
VCC2*21/51 with the serial bus. Connect a
capacitor of 1μF between this pin and GND2.
