Timing Units
Structure
A timing unit is a set of analog and digital resources aimed at producing all internal and external relevant timing signals in relation with a camera.
A timing unit is closely associated to a camera connector. According to the synchronization mode, the timing unit delivers timing data to the camera, and/or senses timing data from the camera.
Domino Alpha 2 owns two identical high performance timing units, referred to as X and Y. Conceptually, the two timing units can be considered as linked to the X and Y camera connectors.
Each Domino Alpha 2 timing unit is able to support anyone of the three synchronization modes (analog synchronization, digital synchronization, master synchronization).
The timing units structure can be conceptualized as follows.
Timing units
The control router device consistently assigns one or two digitizing unit(s) to a given timing unit. This is automatically taken in charge by the MultiCam system according to the connection topology and configuration requested by the user.
The task of a timing unit is to generate appropriate timing signal to a digitizing unit. A single timing unit can take control of one or two digitizing units. A given digitizing unit should obey to one and only one timing unit.
Master Operation
When operated in the master synchronization mode, Domino Alpha 2 delivers a horizontal drive pulse to the camera.
The frequency of this synchronization signal, as reported by the LineRate_Hz parameter, is restricted to the following values:
- 15,625 Hz
- 15,734 Hz
- 23,230 Hz
- 31,250 Hz
- 31,468 Hz
