HSP48212
Digital Video Mixer
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 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).
