SYNC1 IN
SYNC2 IN
Composite SYNC input pin to separate into
H- and V-SYNC.
Input the signal via a clamp capacitor.
Remark: SYNC1 IN is not available, when
A-SYNC = 1 (ON).
Sync tip level: 1.8 V (typ.)
or
1Vp-p
31
30
HD IN
VD IN
HD or VD input pin.
Input a separated horizontal or vertical sync
signal (1.0 to 2.0 Vp-p) via a resistor and a
coupling capacitor.
The polarity of the input signal is detected
and its leading edge becomes a timing
trigger.
1.45 V bias (typ.)

HD OUT
VD OUT
HD or VD output pin.
The polarity of the output is selectable by
HV-POL register.
The tailing edge of the VD-OUT has a jitter.
Use the leading edge only.

FB1 OUT
FB2 OUT
FB output pin.
Note: If necessary, a resistor can be added
between the pin and GND to improve the
transient of the falling edge. The value of
the resistor must be 440
or more.
However, when the resistor is added, the
leak pulse from FB edges to video signals is
also increased.

SYNC FILTER
A filter pin for sync detection.
Connect a capacitor between this pin and
GND.
