GENERAL DESCRIPTION
The SAB9077H is a picture-in-picture controller for multi-standard TV-sets. The circuit contains ADCs, reduction circuitry, memory control, display control and DACs.

FEATURES
Display
• 50/60 Hz PIP modes possible
• 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 needed as external VDRAM (2 × 1 Mbit or 1 × 2 Mbit)
• Four 8-bit Analog-to-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-to-Analog 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.

I2C-bus programmable
