SCAN SENSE TIMING
IS4110 Timing Diagram
The SCAN SENSE pulse occurs once for each flip cycle. A flip cycle represents
one scan in each direction (right to left then left to right from the scanner
perspective). The HIGH to LOW transition of the SCAN SENSE signal initiates
the start of the flip cycle.
The frequency of the SCAN SENSE pulses is dependent on the frequency of the
internal flipper. This varies from unit to unit from 26 Hz to 30 Hz. Therefore, the
period of the SCAN SENSE pulses will vary from 33 ms to 39 ms.
