PIN
No.
PIN NAME
FUNCTION
INTERFACE CIRCUIT
INPUT / OUTPUT
SIGNAL
8
Comm Cent
Adjusts common output center voltage.
When left open, biased 5V.
Voltage on this pin is used as common
output center voltage.
DC input
Adjustable voltage
range :
0.3 to 11V
9
VDD (+13V)
VDD pin
Connect 13V (typ.).
Depending on RGB output load or
adjustment conditions,
oscillation waveform may appear on
output pin. Thus, connect a bypass
capacitor near this pin.
―
11
Comm AMP
Adjusts common output
amplitude.
When left open, biased 2.5V.
When voltage is adjusted to 2.5V,
amplitude of Comm FB is about 5Vp-p.
DC current input :
0.2mA
(sink current) to
1.25mA
(source current)
VCOM amplitude :
0Vp-p to 8.8Vp-p
10
Comm F.B.
Inputs common output feedback signal.
Connect common output buffer.
Maximum output current
: 250A.
Control Comm Out pin
waveform so that common drive
waveform input to this pin has center
voltage and amplitude which are set by
Comm Cent and Comm AMP pins.
12
Comm Out
Outputs drive signal for common
output buffer.
Connect common drive buffer.
