GENERAL DESCRIPTION
VV5409 is a highly-integrated CMOS camera with output in 3 digital video formats:
1. 525 line, 60 fps - 306 x 244 image size -13.5 MHz or 14.31818 MHz crystals.
2. 625 line, 50 fps - 356 x 292 image size -13.5 MHz or 17.734475 MHz crystal.
3. “VV6404 mode” - 356 x 292 image size .
VV5409 contains a two stage flash 8-bit analogue-todigital converter. Device set-up is fully automatic through the CMOS sensor’s built in automatic black level calibration algorithm.
The main features of the sensor’s digital interface are as follows:
1. Tri-stateable 1 / 2 / 4 - wire output video-data-bus for 8-bit video-data. Frame and line format information is encoded within the video output data stream.
2. A 2-wire serial-interface for controlling the operation of the sensor.
3. Data qualification clock, QCK (Tri-stateable)
4. Frame synchronisation signal, FST (Tri-stateable)
Exposure and gain values are programmed through the bidirectional 2-wire serial-interface.
