Detailed Description of Output Pins
The CXD3607R generates special pulses that are used by signal processing circuits, etc. These details are
described below.
• WEN (Pin 30)
The CXD3607R outputs a WEN signal that indicates the effective line period output from the CCD image
sensor. The WEN signal is high during the vertical effective line period. For details, see the vertical timing
charts for each drive mode.
When SG stopped is selected by the SG stop setting, WEN is inactive during the SG stopped VD period.
When performing long-time exposure with the shutter V setting, WEN is inactive during the SG stopped VD
period.
Special Drive Sequence (Random trigger shutter drive)
Cameras using the CXD3607R can perform random trigger shutter drive which allows image capturing at an
optional timing. The TRIG pulse is loaded from the TRIG pin at the rising edge of MCKO, and reflected from the
falling edge of the next HD.
The random trigger shutter drive sequence in DRAFT mode is shown below.
