Type-C/DP1.2转VGA转换器LT8711V描述

1. 一般的描述

LT8711V是一款高性能Type-C/DP1.2转VGA转换器，设计用于将USB Type-C源或DP1.2源连接到VGA接收器。
LT8711V集成了一个DP1.2兼容的接收器和一个高速三通道视频DAC。此外，还包括两个CC控制器，用于CC通信，实现DP Alt模式和供电功能，一个用于上行c型端口，另一个用于下行端口。
提供I2S和SPDIF两个数字音频输出接口。I2S接口支持2-ch LPCM, SPDIF接口支持8-ch LPCM或压缩音频，最大采样率均为192kHz。
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。系统控制也可以通过使用专用配置I2C从接口来实现。
LT8711V还支持EDID缓冲，DP/eDP输入检测并自动确定进入省电模式。当LT8711V的接收器锁定输入信号时，MCU可以通过MSA寄存器读取恢复的时序参数以匹配ASSR。在调试全链路训练时，可以通过系统I2C访问DPCD寄存器。一旦采用快速链路训练，系统时间将至少节省400ms。

1. General Description

The LT8711V is a high performance Type-C/DP1.2 to VGA converter, designed to connect a USB Type-C source or a DP1.2 source to a VGA sink.
The LT8711V integrates a DP1.2 compliant receiver, and a high-speed triple-channel video DAC. 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.
Two digital audio output interfaces are available, I2S and SPDIF. The I2S interface supports 2-ch LPCM and the SPDIF interface supports 8-ch LPCM or compressed audio, both 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.
LT8711V also support EDID buffer, DP/eDP input  detection and determine to enter into power saving mode automatically. When the receiver of LT8711V 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. Once the fast link training used, system time will save at least 400ms.
