SAA9750H Datasheet | NXP Semiconductors

FEATURES - Y/C separator for mosaic filter colour CCD which can be used with PAL or NTSC CCDs with horizontal resolution of 510, 670, 720 or 768 pixels - Line sequential colour processing (R- Y) and (B- Y) - 9 bit input signal (the internal processing is 10-bit) - Digital feedback clamp control for Y/C separation - Two 768 × 9 line memories for Y/C separation - Aperture correction using phase linear filters - Coring of LOW level signals to reduce noise - Colour encoder in accordance with the PAL or NTSC system. Colour subcarrier is made by a discrete time oscillator (DTO) operating on system clock - Slew rate controlled outputs for reduction of digital noise - RGB inputs for title mix - High accuracy 8 bit DAC outputs for luminance and chrominance signals QUICK REFERENCE DATA SYMBOL VDDA1 VDDA2 VDDD1 VDDD2 VDDD3 VIH VIL VOH VOL Tamb PARAMETER Y-DAC analog supply voltage (pin 1) C-DAC analog supply voltage (pin 2) digital supply voltage (pin 41) digital supply voltage (pin 53) digital supply voltage (pin 65) HIGH level digital input voltage LOW level digital input voltage HIGH level digital output voltage LOW level digital output voltage operating ambient temperature MIN. 2.7 2.7 2.7 2.7 2.7 0.7VDDD 0 - - 20 TYP. 3.0 3.0 3.0 3.0 3.0 - - - - - Sync Signal Generator (SSG) to generate all necessary timing signals - Serial interface for microprocessor control of CAMDSP settings - Y and C signals accessible to incorporate digital features - Including digital feature functions (mosaic, sepia, solarization, slice and negative/positive inversion). GENERAL DESCRIPTION The Camera Digital Signal Processor (CAMDSP) is intended for use with a mosaic filter colour CCD. The IC generates luminance and chrominance signals from the CCD signal. The device consists of a luminance and colour separator employing two 768 × 9 line memories, a PAL/NTSC encoder, a dual 8-bit video DAC, a Sync Signal Generator (SSG) and a simple serial interface to control many settings.
