FEATURES
DESCRIPTION
DEVICES INCORPORATED
The LF48212 is a high-speed video
alpha mixer capable of mixing video
signals at real-time video rates. It
takes two 12-bit video signals and
mixes them together using an alpha
mix factor. Alpha determines the
weighting that each video signal
receives during the mix operation.
The input video data can be in either
unsigned or two’s complement
format, but both inputs must be in the
same format. Independently con-
trolled programmable delay stages are
provided for the input and control
signals to allow for allignment of
input data if necessary. The delay
stages can be programmed to have
from 0 to 7 delays. The 13-bit output
of the alpha mixer is registered with
three-state drivers and may be
rounded to 8, 10, 12, or 13-bits.
