GENERAL DESCRIPTION

The SAA8113HL is a 2nd generation camera Digital Signal Processor (DSP) designed for low-cost DTV applications. It integrates the DSP core, the Pulse Pattern Generator (PPG), the 80C51 microcontroller and the VDAC in one IC. It is the successor of the SAA8110G, dedicated to analog output cameras.

FEATURES

? High precision digital processing with 10-bit input

? Medium resolution complementary mosaic CCD sensors PAL or NTSC (interlaced mode only)

? Internal PPG, dedicated to SHARP, TOSHIBA and PANASONIC sensors

? Integrated microcontroller (80C51) for control loops Auto Optical Black (AOB), Auto White Balance (AWB) and Auto Exposure (AE)

? Black offset preprocessing

? RGB separation

? RGB processing (colour correction matrix, programmable knee and gamma)

? Separate Y-processing (saturation concealment, programmable knee and gamma)

? RGB to UV conversion (including down-sampling filters)

? Noise reduction in Y and UV

? Display function for system evaluation

? Analog output processing, including PAL/NTSC encoder and 9-bit Video Digital-to-Analog Converter (VDAC)

? Measurement engine (prepared for AE and AWB features)

? Miscellaneous functions, e.g. power management, 7-bit Control DAC (CDAC) serial interface with preprocessing

? VH reference and window timing for internal use

? Master I2C-bus interface for communication with an external EEPROM (containing the default settings)

? Slave I2C-bus interface for communication with an external microcontroller

? Parallel interface for communication with an external EPROM (for ROM code debugging)

? Integrated audio amplifier.

APPLICATIONS

? Low-cost desktop video applications

? Videophone systems.
