GENERAL DESCRIPTION
The SAB9076H is a picture-in-picture controller for NTSC TV-sets. The circuit contains ADCs, reduction circuitry, memory control, display control and DACs. 

FEATURES
Display
• Twin PIP in interlaced mode at 8-bit resolution
• Sub-title mode features built in
• Large display fine positioning area, both channels
   independent
• Only 2 Mbit required as external VDRAM
   (2 × 1 Mbit or 1 × 2 Mbit)
• Four 8-bit Analogue Digital Converters (ADCs; > 7-bit
   performance) with clamp circuit
• Most PIP modes handle interlaced pictures without joint
   line error
• Two PLLs which generate the line-locked clocks for the
   acquisition channels
• Display PLL to generate line-locked clock for the display
• Three 8-bit Digital Analogue Converters (DACs)
• 4 : 1 : 1 data format
• Data reduction factors 1 to 1, 1 to 2, 1 to 3 and 1 to 4,
   horizontal and vertical independent.

2C-bus programmable
• Single and double PIP modes can be set
• Full field still mode available

• Selection of vertical filtering type
• Freeze of live pictures
• Fine tuned display position, H (8-bit), V (8-bit),
   both channels independent
• Fine tuned acquisition area, H (4-bit), V (8-bit),
   both channels independent
• Eight main borders, sub-borders and background
   colours selectable
• Border and background brightness adjustable, 30%,
   50%, 70% and 100% IRE
