摘　　要：在高精度平板显示系统中 ,传统的界面将液晶显示控制器直接与平板图像控制器连接。由于信号的并行满摆幅传输 ,该界面不能解决强电磁干扰及高功耗等问题。给出了一种基于ANSI/TIA/EIA - 6 44标准的低压差分信号 (LVDS)数据发送系统 ,以解决传统数字视频界面的瓶颈问题。该系统采用 0 18μmCMOS工艺进行设计。高速、较少的并行传输线及低电压摆幅等系统特性实现了高速、低功耗、低电磁干扰 ,单通道数据传输率 784Mb/s ,总数据传输率达 392Mb/s的高速数字视频信号的传输。满足了SVGA、XGA、SXGA等显示模式分辨率的要求。该数据发送器采用HSPICE仿真器在各种PVT情况下做了仿真 ,结果表明 ,系统的各项指标满足上述标准 ,部分参数优于标准的要求。In a high-resolution flat panel system, the conventional interface that directly connects a liquid crystal display controller to a flat panel cannot overcome the problems of excessing electromagnetic interference (EMI) and the power caused by fullswing transmission signals in parallel lines. This paper presents a low voltage defferential signal (LVDS) transmitter based on ANSI/TIA/EIA-644 standard so as to solve the bottleneck of the conventional interface. The transmitter is designed with a 0 18μm 3 3V CMOS model. The combination of high-speed, small number of parallel lines and low-voltage swing differential interface results in high-speed, low EMI data transmission and low power system implementation, which can support resolutions from SVGA up to SXGA. The system is simulated at all kinds of PVT conditions by HSPICE. Results show that the specifications of the system meet the need of standard, part parameters superior to specifications of the standard.\;
