8. INPUT OUTPUT SIGNAL SPECIFICATOINS
( 1 ) HD/VD Output Amplitude Specifications
HD
VD
The amplitude level is the representative value when
terminated with 10kΩ.
Output is enabled when the internal switch SJ01 is set
to the OUT side.
2.0 µs to 5.0 µs
( 2 ) VD Input Specifications
* Input impedance: 75W or 1kΩ or greater
* Input amplitude 2.0 to 5.0 V(p-p) (75Ω termination ON
or OFF)
* Voltage and pulse width were measured at RGB con-
nector located on the rear panel.
796H (Partial scanning OFF)
387H (Partial scanning 60fps)
258H (Partial scanning 90fps)
( 3 ) VIDEO INDEX Output Specifications
The amplitude level is the representative value when
terminated with 10kW.
( 6 ) External HD/VD Input Phase Specifications
External HD
rising edge
External HD
The phase relationship of the external HD and VD should correspond to the center phase (i.e., the external HD falling
edge) as illustrated in the above diagram.
External VD falling edge:
Please input within about 100 clock cycles of the standard center phase.
Note that V sync of the video is output with a delay of about 1H from the external VD at the time of reset-restart and
the external trigger mode.
In the normal mode:
Continuously with the HD period of 43.05 µs and VD period of 34.27 ms (partial scanning 60fps: 16.67 ms, partial
scanning 90fps: 11.11 ms ).
Phase timing is as illustrated in the above diagram (with only the falling edge applicable).
In the reset-restart/external trigger mode:
Continuously with the HD period of 43.05 µs. VD (reset) is at an arbitrary timing with the phase of HD being within the
standard of the above diagram.
