Block diagram
The circuit diagram shown on page 5/12 consists of the following functions:
•
IC6 (A/D converter)
•
30 V/24 V conversion circuit
•
Connector CN5 that provides an interface between R44 board and CIS (contact image sensor).
Figure A3.1.5 shows the related signals and block diagram of CIS.
2.
Function
One-line picture data is read in the sequence from the scanning unit (CIS) as SIG signal (analog
data) to A/D converter (analog/digital converter) of IC6. After conversion from analog data to 6-
bit digital signal (SDATA0 - SDATA5) under the control of IC6, this picture data is sent to
IOGA3 (input/output gate array). Here, the picture data undergoes various kinds of picture
processings.
