Digital Signal Processor (DSP) for

cameras

Preliminary specification

SAA8110G

FEATURES

• High precision digital processing with 9 or 10 bit input

• Different types of CCDs (PAL, NTSC and CIF)

(progressive, interlaced and non-interlaced)

• Black offset preprocessing (including optical black offset

control)

• RGB-separation (with contour and white clip signals

generation)

• RGB-processing (colour space matrix, black control,

knee and gamma)

• RGB-to-YUV conversion (including down-sampling

filters)

• White balance control

• Y-processing (contour processing, false colour detector,

filters and noise reduction)

• UV-processing (false colour correction and noise

reduction)

• Digital output formatter (including CIF-formatter, DTV2,

D1)

• Analog output preprocessing (including

PAL/NTSC-encoder and DACs)

• Measurement engine (prepared for auto-exposure and

auto-white balance features)

• Miscellaneous functions (e.g. switched mode power

supply pulse generator, control DAC)

• VH-reference and window timing

• Serial interface (selectable I2C-bus or 80C51 UART

interface)

• Mode control (including power management).

APPLICATIONS

• Desktop video applications

• Surveillance systems

• Video-phone systems.

GENERAL DESCRIPTION

The SAA8110G is designed for desktop video applications

(teleconferencing, video grabbing), surveillance and

video-phone systems.

The SAA8110G may be applied together with an analog

front-end (TDA8786 including CDS/AGC/ADC), a timing

generator and a microcontroller as shown in

Figs 18 and 19. Other configurations are also possible.

The CCD-sensor can be of PAL, NTSC or CIF type (with

complementary mosaic colour filter). The maximum

number of active pixels is limited to 800 samples/line.

The 10-bits digital input may have a pixel frequency of up

to 14.318 MHz.

The SAA8110G output data is available in a digital and an

analog output format. Two digital output formats are

selectable: DTV2 (CCIR-601 at the input pixel frequency)

and D1 (CCIR-656 at twice the input pixel frequency). It is

also possible to generate the CIF and QCIF formats as

subsets from the processed CCD-image. The analog

output is available in one of four formats: RGB, YUV, YC

or CVBS. The SAA8110G includes a digital

PAL/NTSC-encoder and 3 DACs for this purpose.

Two types of serial interface are selectable: a fast 400 kHz

I2C-bus interface or a 80C51 UART interface (with bit rates

from 1 Mbit/s up to 3.75 Mbit/s depending on the system

clock used). The power dissipation of the SAA8110G can

be optimized for each application using the built-in power

management function.
