4.7: Exposure:
Strobe Signal
The RMV Strobe
signal is a 3.3V LVTTL signal
that is active whenever the CCD is exposing and image.
The strobe signal is very useful for analyzing and optimiz-
ing imaging applications. The strobe can be used to acti-
vate an illumination source. The strobe signal should
cannot drive significant current and should be buffered if
used in this fashion.
Quick FAQ’s:
►The strobe signal can be used to determine frame
timing.
►
The strobe signal can be found on the RMV power
connector and is a 3.3V LVTTL signal.
►
The exposure detector measures the strobe signal
in increments of the pixel clock.
