SAA8110G Digital Signal Processor (DSP) For Cameras

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 . 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.
