Overview
INTEGRATED CIRCUITS DATA SHEET SAA7112 Decoder with High-Performance Scaler (HPS) for Image Port (PELICAN) Preliminary specification File under Integrated Circuits, IC22 1996 Jun 20 Philips Semiconductors Preliminary specification Decoder with High-Performance Scaler (HPS) for Image Port (PELICAN) FEATURES The PELICAN SAA7112 is a video capture device for application at the image port of a VGA controller, with following feature highlights: Video Decoder • Six analog inputs, internal analog source selectors, (e.
g.
6 × CVBS or(2 × YC and 2 × CVBS) or (1 × YC and 4 × CVBS) • Two analog preprocessing channels, including built in analog anti-alias filters • Fully programmable static gain for the main channels or Automatic Gain Control (AGC) for the selected CVBS/Y channel • Two 8 bit video CMOS Analog-to-Digital Converters (ADCs) • Automatic Clamp Control (ACC) for CVBS, Y and C • Switchable white peak control • On-chip line locked clock generation in accordance with CCIR-601 • Digital PLL for synchronization and clock generation from all standards and non-standard video sources, e.
g.
consumer grade VTR • Requires only one crystal (32.
11 MHz) for all standards • Horizontal and vertical sync detection • Automatic detection of 50/60Hz field frequency, and automatic switching between standards PAL and NTSC • Luminance and chrominance signal processing for PAL BGHI, PAL N, PAL M, NTSC M, NTSC N, NTSC 4.
43 and SECAM • User programmable luminance peaking or aperture correction • Cross-colour reduction for NTSC by chrominance combination filtering • PAL delay line for correcting PAL phase errors • Real time status information output (RTCO) • Independent Brightness Contrast Saturation (BCS) adjustment for decoder part.
Video Scaler • Horizontal and vertical down-scaling and up-scaling to randomly sized windows • Horizontal and vertical scaling range: 2 (zoom) to 1⁄64 (icon); vertical zoom might be restricted • Anti-alias- and accumulating filter for horizontal scaling SAA711...
