Figure 7 CCD B/W Camera Block Diagram
Generates the reference frequency for synchronization signal and timing pulse generation: 28.375 MHz
Generates the pulses required for video signal processing (SYNC, blanking, and other signals) and the
pulses required for CCD drive.
Includes a built-in CCD horizontal driver circuit.
Provides an electronic iris function
Amplifies the above pulses to their stipulated amplitudes to drive the CCD element.
Drive pulse level shifting
Video signal processing, including sample and hold, clamp, AGC, gamma correction, white clipping, and
pedestal addition.
