SAB9077H Overview
SAB9077H 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. It inserts one or two live video signals with original or reduced sizes into a live video signal.
SAB9077H Key Features
- 50/60 Hz PIP modes possible
- Twin PIP in interlaced mode at 8-bit resolution
- 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
