CXD2428Q
Video Scan Converter
Description
The CXD2428Q is an IC which generates control
signals and performs line interpolation calculations
for field memory (CXK1206AM/ATM) in order to
perform video signal scanning line conversion. In
addition, this IC performs the aspect conversion of
the ZOOM mode and WIDE-ZOOM mode in order to
support wide screens.
