8. APPLICATION CIRCUITS
8.1 System Application
Figure 8-1 is the application block diagram of scanner, the photo sensor may be CCD device or CIS
device with single channel or three-channel analog output. The ASIC is used to generate the request
signal of photo sensor, W6662, motor control and other mechanical/electric interface. The memory
buffer is used to temporary store the image data and the data will be transfered to the host through
EPP port or other interface as SCSI. If micro controller is included, some control sequence, photo
sensor calibration or image data procession can be completed without the aid of the host.
