VV5430C001

VV5430 ® Monochrome Analog Output CMOS Image Sensors 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). 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. The integrated 75Ω driver eliminates the need for additional active components to drive standard loads, including double terminated lines. 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. 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. A bi-directional serial interface on the VV5430 allows an external controller to set operational parameters and control exposure and gain values directly.
