1. 描述

LT8711UXE1是一個(gè)高性能的Type-C/DP1.2到HDMI2.0轉(zhuǎn)換器，設(shè)計(jì)用于連接USB Type-C源或DP1.2源到HDMI2.0接收器。LT8711UXE1集成了符合DP1.2標(biāo)準(zhǔn)的接收機(jī)和符合HDMI2.0標(biāo)準(zhǔn)的發(fā)射機(jī)。此外，還包括兩個(gè)CC控制器，用于CC通信，實(shí)現(xiàn)DP Alt模式和功率傳遞功能，一個(gè)用于上游Type-C端口，另一個(gè)用于下游端口。

DP接口由4個(gè)主通道、AUX通道和HPD信號(hào)組成。接收端最大支持5.4Gbps的數(shù)據(jù)速率。DP接收機(jī)采用HDCP1.3和HDCP2.3內(nèi)容保護(hù)方案，并嵌入密鑰，實(shí)現(xiàn)數(shù)字音視頻內(nèi)容的安全傳輸。

HDMI接口包括4個(gè)TMDS時(shí)鐘/數(shù)據(jù)對(duì)、DDC和HPD信號(hào)。HDMI發(fā)射器能夠支持高達(dá)6Gpbs的數(shù)據(jù)速率，足以處理超高清4k 60Hz格式的視頻分辨率。HDMI發(fā)射器包含了支持HDCP1.4和HDCP2.3的HDCP引擎。隨著HDCP的加入，LT8711UXE1允許安全傳輸受保護(hù)的內(nèi)容。內(nèi)置密鑰，提供最高級(jí)別的HDCP密鑰安全性。

LT8711UXE1除提供數(shù)字視頻輸出接口外，還提供數(shù)字音頻輸出接口I2S和SPDIF。音頻流從DP數(shù)據(jù)流中提取和恢復(fù)，然后路由到數(shù)字音頻輸出或HDMI輸出。該設(shè)備支持8通道LPCM或壓縮音頻在最大192kHz的采樣率。

該設(shè)備能夠自動(dòng)操作，這是由一個(gè)集成的微處理器，使用嵌入式SPI閃存固件存儲(chǔ)。系統(tǒng)控制也可以通過使用專用的配置I2C從接口來實(shí)現(xiàn)。

1. Description

The LT8711UXE1 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 LT8711UXE1 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 DP interface comprises 4 main lanes, AUX channel, and HPD signal. The receiver supports maximum 5.4Gbps data rate per lane. The DP receiver incorporates HDCP1.3 and HDCP2.3 content protection scheme with embedded key for secure transmission of digital audio-video content.
The HDMI interface includes 4 TMDS clock/data pairs, DDC, and HPD signal. The HDMI transmitter is capable of supporting up to 6Gpbs data rate, quite adequate for handling video resolutions up to UHD 4k 60Hz formats. The HDMI transmitter incorporates HDCP engines which support HDCP1.4 and HDCP2.3. With the inclusion of HDCP, the LT8711UXE1 allows secure transmission of protected content. Embedded key is available that provides the highest level of HDCP key security.
Besides digital video output interface, the LT8711UXE1 also provides digital audio output interfaces: I2S and SPDIF. The audio stream is extracted and recovered from DP data stream, and then routed to digital audio outputs or HDMI output. The device supports 8-channel 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.
