SAB9080 NTSC Picture-In-Picture (PIP) Controller

The SAB9080 is an NTSC PIP controller which CAN be used in double window applications. The SAB9080 inserts one or two live Video signals with reduced size into another live Video signal. The incoming Video signals are expected to be Analog baseband signals. The conversion to the digital environment is done on chip with ADCs Processing and storage of the Video data is done entirely in the digital domain. The conversion back to the Analog domain is done by DACs Internal Clocks are generated by PLLs which lock on to the applied horizontal and vertical syncs. The main input channel is compressed horizontally by a factor of two and directly fed to the output. After compression, a horizontal expansion of two is possible for the main channel. The subchannel is also compressed horizontally by a factor of two but stored in memory before it is fed to the outputs.
