SDA9488X中文资料MICRONAS数据手册PDF规格书

General Description

SDA 9488X ’PIP IV Basic’ and SDA 9588X ’OCTOPUS’ belong to a new generation of costeffective PiP processors that combine high-quality digital PIP signal processing, digital multistandard color decoding and AD/DA conversion on a single chip. Both devices are equipped with CVBS and Y/C input interfaces. In addition the SDA 9588X is also able to process YUV input signals for displaying high-quality video signals e.g. coming from a DVD source.

特性 Features

• Single chip solution:
