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.
The HSP48212 input and output interfaces are synchronous with respect to the input clock, simplifying the user interface requirements.
Input Data (DINA, DINB), Mix Factor (M) and control signals (RND, TCB) may be delayed relative to each other in order to compensate for any misalignment that may have occurred prior to entering the HSP48212. Each input's delay may be independently programmed up to seven clock cycles.
The output data may be rounded to 8, 10, 12, or 13-bits. The enabling of data onto the output data bus is under the user's control via an output enable signal (OE).
