10.4 External Sync and Pixel Locking
The TM-2030GE accepts an external sync of standard HD and VD at TTL level for general locking to a
system sync and clock. The frequency requirement is as follows:
Full Progressive Scan:
fHD = 36.36 KHz ± 2%
fVD = 32.32 Hz ± 2%
(Internal Master clock = 80.00 MHz,
Pixel clock = 40.00 MHz)
10.5 Electronic Shutter
The TM-2030GE has a substrate drain-type shutter mechanism which provides a superb picture at var-
ious speeds without smearing.
10.5.1 Programmable Exposure-Continuous Mode
The exposure time of TM/TMC-2030GE can be specified from one video line to a maximum of one
frame using the serial communication commands in the Continuous Mode. There is overhead where the
specified exposure time is
n
video lines, making the real exposure time equal to
When
n
=0, the exposure time is the minimum exposure time. It is equal to:
In this mode the maximum exposure time is equal to the setting for one frame. If the user specified
exposure time is longer than the time allowed for one frame, it will be ignored by the camera.
