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 SAA8110G 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 SAA8110G 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.
