描述
LT8711UXE1是一種高性能的Type-C/DP1.2到HDMI2.0轉(zhuǎn)換器,設(shè)計用于連接USB Type-C源或DP1.2源到HDMI2.0接收器。LT8711UXE1集成了一個DP1.2兼容的接收機和一個HDMI2.0兼容的發(fā)射機。CC通信采用兩個CC控制器,分別為上游Type-C端口和下游Type-C端口,實現(xiàn)DP Alt模式和供電功能。
DP接口由4個主通道、AUX通道和HPD信號組成。接收器支持每道最大5.4Gbps數(shù)據(jù)速率。DP接收機采用HDCP1.3/2.3內(nèi)容保護方案和嵌入式密鑰,實現(xiàn)數(shù)字音視頻內(nèi)容的安全傳輸HDMI接口包括4個TMDS時鐘/數(shù)據(jù)對、DDC和HPD信號。HDMI發(fā)射機能夠支持高達6gbs的數(shù)據(jù)速率,非常適合處理超高清4k 60Hz格式的視頻分辨率。HDMI發(fā)射機集成了HDCP引擎,支持HDCP1.4/2.3。通過包含HDCP, LT8711UXE1允許安全傳輸受保護的內(nèi)容。嵌入式密鑰是可用的,提供最高級別的HDCP密鑰安全性。
除了數(shù)字視頻輸出接口,LT8711UXE1還提供數(shù)字音頻輸出接口I2S和SPDIF。從DP數(shù)據(jù)流中提取并恢復(fù)音頻流,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或最大192kHz采樣率的壓縮音頻。該設(shè)備能夠通過集成的微處理器實現(xiàn)自動操作,該微處理器使用嵌入式SPI閃存進行固件存儲。通過使用專用配置I2C從接口,還可以進行系統(tǒng)控制。

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 HDCP1.3/2.3 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 HDCP1.4/2.3. 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.
