LT8712EXC是一款高性能的Type-C/DP1.2到HDMI2.0/VGA转换器

1. 描述

LT8712EXC是一款高性能的Type-C/DP1.2到HDMI2.0/VGA转换器，设计用于将USB Type-C源或DP1.2源同时连接到VGA接收器和HDMI2.0接收器。

LT8712EXC集成了一个符合DP1.2的接收机(MST能力)，一个高速三通道视频DAC和一个符合HDMI2.0的发射机。CC通信采用两个CC控制器，分别为上游Type-C端口和下游Type-C端口，实现DP Alt模式和供电功能。片上USB3.0交换机是一种高速双向无源交换机，提供灵活的开关以适应连接器翻转。该开关还可以处理2-ch数据/ 2-ch视频和所有4-ch视频之间的muxing。

有两个数字音频输出接口，I2S和SPDIF。两者都支持8-ch LPCM或最大192kHz采样率的压缩音频。

该设备能够通过集成的微处理器实现自动操作，该微处理器使用嵌入式SPI闪存进行固件存储。通过使用专用配置I2C从接口，还可以进行系统控制。

1. Description

The LT8712EXC 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 an HDMI2.0 sink simultaneously.

The LT8712EXC integrates a DP1.2 compliant receiver (MST capable), a high-speed triple-channel video DAC and an HDMI2.0 compliant transmitter. 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.
