E17 Circuit Diagram
1.
Block diagram
The circuit diagram shown on page 4/16 consists of the following function:
•
IC6 (A/D converter) and amplifier
•
30 V/24 V conversion circuit
•
Connector CN10 that provides an interface between E17 board and CIS (contact
image sensor).
Figure A3.1.4 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 via amplifier. After conversion
from analog data to 6-bit digital signal (SDT2 - SDT7) under the control of IC6, the picture data
is sent to IEXSEED300 (scanning control LSI) of IC20. Here, the picture data undergoes
various kinds of picture processings.
Sensor interface signal output from IEXSEED300.
