Introduction

Etrons EL7301 is the key graphics processing IC that enable liquid Crystal Display (LCD) monitor at SVGA, XGA and SXGA TFT-LCD resolution. This single chip solution included a triple-channel ADC, two PLL circuits, one internal On Screen Display (OSD), sophisticated filter and the most advanced scaling engine. The digital or video input can also be supported via analog/digital input ports that implemented in EL7301.
