EP148

Part Number:EP148

Overview

EP148 is a 4-lane iDP (Internal Display Port) transmitter with 4-port 10-bit LVDS inputs. The chip receives video data from 2 or 4 LVDS ports and output the video data through a 2 or 4-lane iDP transmitter. Converting the video data from LVDS inputs to iDP outputs will greatly reduce the number of signal pairs required to carry the data. The chip can reduce number of signal pairs from 24 LVDS pairs to 4 iDP pairs. This will greatly reduce the cost of connectors and cables and is suitable for high frame rate and 3D flat panel applications.

Features
