Sun Expert3D 7-Pin DIN Female Stereo Connector
External Video Synchronization Port
The external video synchronization port uses a 75-Ohm BNC male connector. A
75-Ohm coax cable terminated with a female BNC connector is needed to connect to
this port and provide a periodic signal to which the display system attempts to lock
its vertical refresh rate.
The supported formats are:
■
NTSC composite video
■
PAL composite video
■
TTL, LVTTL, or CMOS level compatible periodic signal (50 Hz–180 Hz), with a
minimum low or high pulse or 100ns (TBV)
