1 General Description

1.1 Introduction

WSC2800 series is an advanced video format converter, which converts digital inputs into multiple formats.

The series has two members.

WSC2800 converts into analog output (CVBS and RGB).

WSC2810 outputs

digital forms (RGB and YUV).

The series supports a wide range of configurable formats, with both SD

(standard definition) and HD (high definition) input supported.

So that, the series can be applied to many

high-speed and high-quality video conversion applications
