(CAMDSP)

Preliminary specification

SAA9750H

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

• 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.
