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.
SAB9077H 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 base band signals. The conversion into the digital environment of SAB9077H and back to the analog environment is done on chip. Internal clocks are generated by two acquisition PLLs and a display PLL.
The two PIP channels of SAB9077H and a large external memory offer a wide range of PIP modes. The emphasis is put on single PIP, double PIP, split-screen mode and many multi-PIP modes.
