CXD2428Q

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.

100 pin QFP (Plastic)

Features
