1 / 54 page  ® Mono and Colour Digital Video CMOS Image Sensors CD5404-6404F-A 1/54 VV5404 & VV6404 DESCRIPTION VV5404 and VV6404 are highly integrated CMOS VLSI sensors which enables high standards of performance and image quality at a very cost-effective price point. The 356 x 292 monochrome device offers one of the simplest routes currently available to design-in of imaging applications, while the colour device is ideal for low cost PC camera applications. Both devices incorporate a comprehensive range of on-board controls eliminating the need for additional support chips. On- chip A/D conversion provides 8 bit digital output and the device set up is fully automatic via the built-in automatic black level calibration algorithm. Exposure and gain settings are programmable and operation is controlled via a serial interface. This sensors offer variable frame rates of up to 30 frames per second and a 4 wire digital video bus. The digital interface also provides a tri-stateable data qualification clock and frame synchronisation signal. Hand-held products, in applications such as PDAs, bar code scanning or automatic meter reading, will benefit from the low power requirements and from the inbuilt sleep and power down modes. The price and performance standards introduced with the VV5404 and VV6404 enable use of an imaging solution where previously it may not have been practicable on cost grounds. BLOCK DIAGRAM FEATURES • CIF Format mono or colour pixel array • Up to 30 frames per second operation • On-chip 8 bit analogue to digital converter • Low power consumption • Up to 356 x 292 pixel image size • Automatic exposure and gain control • Serial interface control • Programmable exposure and gain values • Automatic black level calibration • 4-wire digital video bus • Evaluation kit available APPLICATIONS • PC Cameras • Biometrics • Inspection Systems SPECIFICATIONS Important: 1. A colour co-processor is required to convert the VV6404 sensor’s video data stream of raw colourised pixel data into either a CIF or QCIF for- mat RGB or YUV colour image. 2. VV5404 and VV6404 do NOT have any form of automatic exposure control. This must be performed externally. SAM PLE & HO LD HORIZO NTAL SHIFT PHOTO DIODE ANALO G VO LTAG E REFS.
