VV5404 & VV6404
Mono and Colour Digital Video CMOS Image Sensors
FEATURES
®
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.

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
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.
Programmable exposure and gain values
Automatic black level calibration
4-wire digital video bus
Exposure and gain settings are programmable and operation
is controlled via a serial interface.
Evaluation kit available
APPLICATIONS
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.

Inspection Systems
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.

Important:
SAMPLE & HOLD
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.
