SYNC IN 2
SYNC IN 1
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
23
22
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.)
or

CVBS/Y/GOUT
Cb/B OUT
Cr/R OUT
Video signal output pin.
Refer to Bus Control Functions for the
output from each pin.
AC: -3, 0 or +3 dB (typ.)

AL1 OUT
AR1 OUT
AL2 OUT
AR2 OUT
Audio signal output pin.
Refer to Bus Control Functions for the
output from each pin.
64
MONITOR OUT
Video signal output pin for a monitor output.
Refer to Bus Control Functions for the
output from the pin.

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.
10
SYNC FILTER
A filter pin for sync detection.
Connect a capacitor between this pin and
GND.
