The VV5430 sensor can be used with an Analog-to-Digital Converter (ADC) and the necessary logic to form an image capture
and processing system. The camera provides an analogue video output together with digital signals to qualify this output and
synchronise image capture.
The signals provided for image capture are the following:-
The following diagram illustrates the relative timing of the image capture signals. Scale is not actual but edge succession is
preserved.

• PV,PVB: (Pixel Valid, PV Bar) Complementary signals, their leading edges qualify valid pixel levels.
• LST: (Line STart) The rising edge signals the start of a visible line.
• FST: (Field STart) The rising edge signals the start of a field.
• ODD: Identifies an odd field within a frame.
• CPE (Clock Pulse Enable): Disables generation of PV/PVB and LST signals. The state of this pin is sampled

only during a system reset. Its state after reset can be overridden via the serial interface using Set-up Code_2.
