Description

The SAB9075H is a picture-in-picture controller for the NTSC environment in combination with the Integrated NTSC decoder and sync processor TDA8315.

SAB9075H inserts one or two live video channels with reduced sizes into a live video signal. All video signals are expected to be analog baseband signals. The conversion into the digital environment of SAB9075H and back to the analog environment is carried out on-chip. Internal clocks are generated by two PLLs.

Due to the two PIP channels and a large external memory, a wide range of PIP modes are offered. The emphasis of SAB9075H is put on double-PIP and multi-PIP modes. In combination with the different border colours and some external software the IC concept can be used as an excellent channel selection tool.

Some of the I2C-bus registers are for controlling the saturation and HUE of the colours. There are also outputs of SAB9075H  for the mute function of main and sub-channel.
