1. 描述
LT8712EXI高性能Type-C/DP1.2到HDMI2.0/VGA用于连接转换器的设计USB Type-C源或DP1.2源到VGA同时连接两个接收器HDMI2.0接收器。
LT8712EXI整合一个符合DP1.2标准的接收机(支持MST)，高速三通道视频DAC和两个符合HDMI2.0标准发射机。 还有两个CC用于控制器CC通信，实现DP Alt上游使用模式和功率传输功能Type-C另一个端口用于下游端口。 片上USB3.0开关是一种适应连接器翻转的高速双向无源开关。 该开关还可以处理2通道数据/ 2通道视频与所有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或者最大1922年压缩音频kHz的采样率。
该设备由嵌入式微处理器自动操作SPI存储闪存固件。 系统控制也可以使用特殊配置I2C实现接口。

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.? USB Type-C? DP1.2 Receiver? Dual HDMI2.0 Transmitters? Triple-Channel Video DAC?
