Type-C/DP1.2轉VGA轉換器LT8711V描述

1. 一般的描述

LT8711V是一款高性能Type-C/DP1.2轉VGA轉換器，設計用于將USB Type-C源或DP1.2源連接到VGA接收器。
LT8711V集成了一個DP1.2兼容的接收器和一個高速三通道視頻DAC。此外，還包括兩個CC控制器，用于CC通信，實現DP Alt模式和供電功能，一個用于上行c型端口，另一個用于下行端口。
提供I2S和SPDIF兩個數字音頻輸出接口。I2S接口支持2-ch LPCM, SPDIF接口支持8-ch LPCM或壓縮音頻，最大采樣率均為192kHz。
該設備能夠通過集成的微處理器實現自動操作，該微處理器使用嵌入式SPI閃存進行固件存儲。系統控制也可以通過使用專用配置I2C從接口來實現。
LT8711V還支持EDID緩沖，DP/eDP輸入檢測并自動確定進入省電模式。當LT8711V的接收器鎖定輸入信號時，MCU可以通過MSA寄存器讀取恢復的時序參數以匹配ASSR。在調試全鏈路訓練時，可以通過系統I2C訪問DPCD寄存器。一旦采用快速鏈路訓練，系統時間將至少節省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.
