1.说明
Lontium LT8718是TTL到DP转换器，带有内部Type-C备用模式开关和PD控制器。
在SDR或DDR采样下，输入支持正常的24位RGB / YUV和BT656 / BT1120模式。RGB输入最大分辨率为4Kx2K @ 30Hz，YUV420输入最大分辨率为4Kx2K @ 60Hz。
为了适应最新的USB C型生态系统，LT8718集成了一个高性能双向无源差分开关，由CC逻辑和PD管理单元控制，以减轻移动系统设计的复杂性和BOM成本。开关功能符合USB C型标准上的VESA DP备用模式。
LT8718采用先进的CMOS工艺制造，并以10mmx10mm的小型QFN88（LT8718-Q88）实现。该封装符合RoHS要求，并规定在-40°C至+ 85°C的温度范围内工作。

The Lontium LT8718 is TTL to DP converter with internal Type-C Alternate Mode switch and PD controller.
The input supports both normal 24-bit RGB/YUV and BT656/BT1120 mode under SDR or DDR sampling. The maximum resolution is up to 4Kx2K@30Hz for RGB input and 4Kx2K@60Hz for YUV420 input.
In order to be adaptable to the latest USB Type-C ecosystem, LT8718 integrates a high performance bi-directional passive differential switch controlled by CC logic and PD management unit to relieve mobile system design complexity and BOM cost. The switch function is compliant with VESA DP Alternate Mode on USB Type-C Standard.
The LT8718 is fabricated in advanced CMOS process and implemented in a small outline 10mmx10mm QFN88. This package is RoHS compliant and specified to operate from -40°C to +85°C.
