VV5411 & VV6411
Mono and Colour Digital Video CMOS Image Sensors
The VV5411/VV6411 are multi-format digital output imaging devices based on STMicroelectronics's unique CMOS sensor technology. Both sensors require minimal support circuitry. The VV6411 and VV5411 are replacements for the VV6410 and VV5410, and are intended to enable even more cost-effective imaging solutions. The 6411 also uses more modern colour filter material to ensure optimum colour performance VV5411 (monochrome) and VV6411 (colourised) produce digital video output. The video streams from both devices contain embedded control data that can be used to enable frame grabbing applications as well as providing input data for an external exposure controller. VV6411 can interface to a range of STMicroelectronics co-processors. A USB camera can be realised by partnering VV6411 with TV0676. A low cost digital stills camera can be produced by operating VV6411 with STV0680B-003. Please contact STMicroelectronics for ordering information on all of these products. Both VV5411 and VV6411 are initialised in a power saving mode and must be enabled via the I2C interface before they can produce a video output. The I2C interface allows the master coprocessor to reconfigure the device and control exposure and gain settings. USB systems are catered for with an ultra low power, pin driven, suspend mode. The on board regulator can supply sufficient current drive to power external components, (e.g. the video coprocessor).
