2-3-5 CCD PCB

CCD IC3
The CCD PCB (CCDPCB) receives clock signals SHIFT+, SHIFT-, CLK+, CLK-, RS+, RS-, CLP+, and CLP- from the main
PCB (MPCB), and based on these signals, generates the CCD drive signal to drive CCD IC3.
When clock signals are input, the CCD IC3 outputs analog signals according to the set density of the image, which are
transmitted to the main PCB (MPCB) via the emitter follower circuits and differential amplifiers IC4, IC5, IC6 and IC7.
