TI DS90C187平板电脑高清晰显示解决方案
TI 公司的DS90C187是低功耗并串转换器(串化器),主要用在以电池为能源的手提设备,能降低主GPU和显示器间的RGB接口的尺寸.器件支持高达QXGA 2048x1536@60Hz分辨率和主机和平板显示器间的双象素数据传输.185MHz时的功耗为100mW,能驱动QXGA/WQXGA显示器,支持24位RGB和48位RGB,有三种工作模式:单象素进/单象素出(SISO),单象素进/双象素出(SIDO)和双象素进/双象素出(DIDO).本文介绍了DS90C187主要特性,SISO,SIDO和DIDO功能框图,以及SIDO模式应用电路, 平板电脑和电子书系统方框图,C187EVK01评估模块(EVM)主要特性,电路图,材料清单和PCB布局图.
The DS90C187 is a Low Power Serializer for portable battery powered application that reduces the size of the RGB interface between the host GPU and the Display.
The DS90C187 Serializer is designed to support dual pixel data transmission between Host and Flat Panel Display up to QXGA 2048x1536@60Hz resolutions. The transmitter converts up to 48 bits (Dual Pixel 24 bit color) of 1.8V LVCMOS data into two channels of 4 data + clock (4D+C) reduced width interface LVDS compatible data streams.
