0 1. 描述 LT8711GX是一个高性能的Type-C/DP1.4到HDMI2.1转换器，设计用于连接USB Type-C源或DP1.4源到HDMI2.1接收器。 LT8711GX集成了一个符合DP1.4标准的接收器和一个符合HDMI2.1标准的发射器。此外，还包括一个CC控制器，用于CC通信，实现DP Alt模式和功率传递功能。该设备能够自动操作，这是由一个集成的微处理器，使用嵌入式SPI闪存固件存储。系统控制也可以通过使用专用的配置I2C从接口来实现。 LT8711GX还支持EDID缓冲，DP/eDP输入检测，并自动确定进入省电模式。当LT8711GX接收机锁定输入信号时，单片机可以通过MSA寄存器读取恢复的定时参数来匹配ASSR。在调试全链接训练时，DPCD寄存器可以通过系统I2C访问。 2. 特性 •USB c型 •DP1.4接收机 •HDMI2.1发射机 •杂项 3. 应用程序 •停靠站 •电子狗 1. Description The LT8711GX is a high performance Type-C/DP1.4 to HDMI2.1 converter, designed to connect a USB Type-C source or a DP1.4 source to an HDMI2.1 sink. The LT8711GX integrates a DP1.4 compliant receiver, and an HDMI2.1 compliant transmitter. Also, one CC controller is included for CC communication to implement DP Alt Mode and power delivery function. The device is capable of automatic operation which is enabled by an integrated microprocessor that uses an embedded SPI flash for firmware storage. System control is also available through the use of a dedicated configuration I2C slave interface. LT8711GX also support EDID buffer, DP/eDP input detection and determine to enter into power saving mode automatically. When the receiver of LT8711GX locks the input signal, the MCU can read the recovered timing parameters by the MSA registers to match the ASSR. The DPCD registers are accessible via system I2C when debugging the full link training. 2. Features • USB Type-C • DP1.4 Receiver • HDMI2.1 Transmitter • Miscellaneous 3.
