1. 描述 LT8711UXE1是一个高性能的Type-C/DP1.2到HDMI2.0转换器，设计用于连接USB Type-C源或DP1.2源到HDMI2.0接收器。LT8711UXE1集成了符合DP1.2标准的接收机和符合HDMI2.0标准的发射机。此外，还包括两个CC控制器，用于CC通信，实现DP Alt模式和功率传递功能，一个用于上游Type-C端口，另一个用于下游端口。 DP接口由4个主通道、AUX通道和HPD信号组成。接收端最大支持5.4Gbps的数据速率。DP接收机采用HDCP1.3和HDCP2.3内容保护方案，并嵌入密钥，实现数字音视频内容的安全传输。 HDMI接口包括4个TMDS时钟/数据对、DDC和HPD信号。HDMI发射器能够支持高达6Gpbs的数据速率，足以处理超高清4k 60Hz格式的视频分辨率。HDMI发射器包含了支持HDCP1.4和HDCP2.3的HDCP引擎。随着HDCP的加入，LT8711UXE1允许安全传输受保护的内容。内置密钥，提供最高级别的HDCP密钥安全性。 LT8711UXE1除提供数字视频输出接口外，还提供数字音频输出接口I2S和SPDIF。音频流从DP数据流中提取和恢复，然后路由到数字音频输出或HDMI输出。该设备支持8通道LPCM或压缩音频在最大192kHz的采样率。 该设备能够自动操作，这是由一个集成的微处理器，使用嵌入式SPI闪存固件存储。系统控制也可以通过使用专用的配置I2C从接口来实现。 2. 特性 •USB c型 •DP1.2接收机 •HDMI2.0发射机 •数字音频输入/输出 •杂项 3.应用程序 •停靠站 •电子狗 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.
