Source Path Selector
The line trigger has five possible source paths. The path is selectable by means of the MultiCam parameter LineRateMode:
- When LineRateMode is set to PULSE, the line trigger signal is generated by the quadrature decoder circuit through a 1/N rate divider.
- When LineRateMode is set to CONVERT, the line trigger signal is generated by the quadrature decoder circuit through a P/Q rate converter.
- When LineRateMode is set to PERIOD, the line trigger signal is generated by a periodic pulse generator.
- When LineRateMode is set to CAMERA, the line trigger is generated by the camera through the LVAL signal. The time interval between line triggers is actually driven by the camera.
- When LineRateMode is set to EXPOSE, the line trigger is generated by the exposure control circuit. The time interval between line triggers is actually driven by the exposure time.
