Type C (DP) to HDMI 2.0 with integrated CC1, MCU, HDCP Key, compatible with LT8711H-C

LT8711HE是一款高性能Type-C / DP1.2至HDMI2.0轉(zhuǎn)換器，旨在將USB Type-C源或DP1.2源連接至HDMI2.0接收器。
LT8711HE集成了符合DP1.2的接收器和符合HDMI2.0的發(fā)送器。此外，還包括兩個CC控制器，用于CC通信以實現(xiàn)DP Alt Mode和功率傳輸功能，一個
用于上游Type-C端口，另一個用于下游端口。該設(shè)備能夠自動運行，這由集成微處理器啟用，該微處理器使用嵌入式SPI閃存進行固件存儲。也可以通過使用專用的配置I2C從接口來進行系統(tǒng)控制。
LT8711HE還支持EDID緩沖器，DP / eDP輸入檢測并確定自動進入省電模式。當LT8711HE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(shù)以匹配ASSR。調(diào)試完整的鏈接訓練時，可通過系統(tǒng)I2C訪問DPCD寄存器。一旦使用了快速鏈接訓練，系統(tǒng)時間將至少節(jié)省400ms。

 

1. General Description

The LT8711HE is a high performance Type-C/DP1.2 to HDMI2.0 converter, designed to connect a USB Type-C source or a DP1.2 source to an HDMI2.0 sink.
The LT8711HE integrates a DP1.2 compliant receiver, 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. The device is capable of automatic operation which is enabled by an integrated microprocessor that uses a embedded SPI flash for firmware storage. System control is also available through the use of a dedicated configuration I2C slave interface.
LT8711HE also support EDID buffer, DP/eDP input  detection and determine to enter into power saving mode automatically. When the receiver of LT8711HE 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.
