SDA9280

General Description

The Picture-in-Picture Processor SDA 9288X A141 generates a picture of reduced size of a video signal (inset channel) for the purpose of combining it with another video signal (parent channel). The easy implementation of the IC in an existing system needs only a few additional external components.
