1. 描述
LT8712EXI是一个高性能的Type-C/DP1.2到HDMI2.0/VGA转换器，设计用于连接USB Type-C源或DP1.2源到VGA接收器，并同时连接两个HDMI2.0接收器。
LT8712EXI集成了一个符合DP1.2标准的接收机(支持MST)，一个高速三通道视频DAC和两个符合HDMI2.0标准的发射机。 此外，还包括两个CC控制器，用于CC通信，实现DP Alt模式和功率传递功能，一个用于上游Type-C端口，另一个用于下游端口。 片上USB3.0开关是一种高速双向无源开关，提供灵活的开关，以适应连接器翻转。 该开关还可以处理2通道数据/ 2通道视频和所有4通道视频之间的多路复用。
提供两个数字音频输出接口，I2S和SPDIF。 两者都支持8-ch LPCM或压缩音频在最大192kHz的采样率。
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。

1. Description
The LT8712EXI is a high performance Type-C/DP1.2 to HDMI2.0/VGA converter, designed to connect a USB Type-C source or a DP1.2 source to a VGA sink and up to two HDMI2.0 sinks simultaneously.
The LT8712EXI integrates a DP1.2 compliant receiver (MST capable), a high-speed triple-channel video DAC and two HDMI2.0 compliant transmitters. Also, two CC controllers are included for CC communication to implement DP Alt Mode and power delivery function, one for upstream Type-C port and another for downstream port. On-chip USB3.0 switch is a high-speed bi-directional passive switch which provides flexible switching to accommodate connector flipping. This switch also handles muxing between 2-ch data / 2-ch video and all 4-ch video.
Two digital audio output interfaces are available, I2S and SPDIF. Both support 8-ch LPCM or compressed audio at maximum 192kHz sample rate.
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.
