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.

SAB9076H inserts one or two live video signals with original or reduced sizes into a live video signal. All video signals are expected to be analog baseband signals.

The conversion of SAB9076H into the digital environment and back to the analog environment is carried out on chip. Internal clocks are generated by two acquisition PLLs and a display PLL.

Due to the two PIP channels of SAB9076H and a large external memory a wide range of PIP modes are offered. The emphasis is put on single-PIP, double-PIP, split-screen mode and a many multi-PIP modes.
