3 说明

SN65DSI85-Q1 DSI 转 LVDS 桥接器 具有 一个双通道 MIPI D-PHY 接收器前端
配置，此配置中在每个通道上具有 4 条信道，每条信道的运行速率为 1Gbps，最大输入带宽为 8Gbps。该桥接器可解码 MIPI DSI 18bpp RGB666 和 24bpp RGB888 视频流，并将格式化视频数据流转换为 LVDS 输出（像素时钟范围为 25MHz 至 154MHz），从而提供一个双链路 LVDS、单链路 LVDS 或两个单链路 LVDS 接口（每个链路具有 4 个数据信道）。

SN65DSI85-Q1 器件非常适用于 60fps 的 WQXGA (2560 × 1600)，以及等效 120fps（高达 24 bpp）的 WUXGA 3D 图形和全高清 (1920x1080) 分辨率。该器件实现了部分线路缓冲以适应 DSI 与 LVDS 接口间的数据流不匹配的情况。

SN65DSI85-Q1 器件采用小外形 10mm × 10mm HTQFP
（0.5mm 间距）封装，工作温度范围为 –40ºC 至 +105ºC。
