SAA9750H 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.
SAA9750H Key Features
- Y/C separator for mosaic filter colour CCD which can be used with PAL or NTSC CCDs with horizontal resolution of 510, 67
- 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)
- Slew rate controlled outputs for reduction of digital noise
- RGB inputs for title mix
