VV5430  
Monochrome Analog Output CMOS Image Sensors  
KEY FEATURES  
®
DESCRIPTION  
The VV5430 is a highly-integrated VLSI camera device  
based on the unique CMOS sensor technology from  
STMicroelectronics. It delivers a fully-formatted composite  
monochrome video signal. Standards options include EIA  
(320 x 244) and CCIR (384 x 287).  
Complete Video Camera on a single chip  
Minimal support circuit  
EIA/CCIR standard compatible options  
Low power operation - single voltage supply  
Integral 75 ohm driver  
It is possible to develop a single chip video camera using this  
device that requires only supply voltage in, and delivers  
composite video out for connection to a video monitor.  
384 x 287 pixel array  
The integrated 75driver eliminates the need for additional  
active components to drive standard loads, including double  
terminated lines.  
Automatic exposure and gain control  
Linear or gamma corrected output option  
Automatic black level calibration  
Serial Interface Control  
It is also suitable for applications requiring the digitisation of  
the video signal or external microprocessor control.  
In the VV5430 Frame, Line and Pixel timing signals are  
provided to facilitate pixel-locked digitisation of the analog  
video data. In addition to the these outputs a synchronisation  
input (SIN) is also provided to allow the start of frame to be  
synchronised to an external event.  
Frame and line timing signals for external ADC  
APPLICATIONS  
Security/Observation systems  
Biometric identification  
Toys and games  
The device features automatic exposure control that allows a  
fixed-aperture lens to be used, and incorporates Normal and  
Backlit modes to give operation over a wide range of scene  
types.  
Digital Image capture systems  
SPECIFICATIONS  
A bi-directional serial interface on the VV5430 allows an  
external controller to set operational parameters and control  
exposure and gain values directly.
