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-to-

digital 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 bi-

directional 2-wire serial-interface.

Important:

A host processor is required to perform Automatic Exposure and Gain control (AEC/AGC) via the sensor

serial interface, and to generate an appropriate video output timing format.
