ABSTRACT:
The present invention is a clock signal apparatus for a document scanner that only produces a clock signal when pixel data is output. The apparatus includes a timing and control unit 94 that not only controls the sensor analog output process along with the conversion of the analog signals to digital data, but also provides a video clock signal only when the sensor data is present at the output of the scanner. The unit 94 also provides an intersensor period during which no pixel data is output and no clock signal is produced. The unit 94 supplies a horizontal synchronization signal before the video clock is started and a horizontal synchronization signal immediately after the last data is transmitted. The receiving unit 72 latches the data synchronous with the video clock signal. The video clock signal includes multiple edges allowing the various edges to control various stages of further processing of the sensor data.
