The Intersil HSP48212 is a 68 pin Digital Video Mixer IC intended for use in multimedia and medical imaging applications.

The HSP48212 allows the user to mix two video sources based on a programmable weighting factor. After weighting the input data signals, the Video Mixer simply adds the two weighted signals mathematically. This results in the mixed output, which is a weighted sum of the two sources.
