1. 描述

LT7911UXC是一个高性能的Type-C/DP1.4a到MIPI或LVDS芯片的VR/显示应用。

HDCP RX作为HDCP中继器的上游，可以与其他芯片的HDCP TX配合实现中继器功能。

对于DP1.4a输入，LT7911UXC可以配置为1/2/4 lanes。自适应均衡使其适合长电缆应用和最大带宽高达32.4Gbps。

对于MIPI输出，LT7911UXC具有可配置的单端口或双端口或四端口MIPI®DSI/CSI，具有1个高速时钟通道和1~4个高速数据通道，以最大2.5Gbps/lane使用D-PHY，可支持4个端口的总带宽高达40Gbps。LT7911UX还支持5.7Gbps/lane与C-PHY，可以支持总带宽高达68.4Gbps的四个端口。

对于LVDS输出，LT7911UXC可配置为单端口、双端口或四端口LVDS, 1条高速时钟通道，3~5条高速数据通道，每条通道的最大工作速率为1.2Gbps，可支持总带宽高达24Gbps。LT7911UXC支持灵活的视频数据映射路径的2D和3D应用程序。

提供两个数字音频输出接口I2S和SPDIF。I2S接口支持8通道LPCM, SPDIF接口支持2通道LPCM或压缩音频，采样率均为192khz。

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。系统控制也可通过配置I2C从接口。

LT7911UXC采用先进的CMOS工艺制作，在9mmx9mm BGA169封装中实现。

1.Description

The LT7911UXC is a high performance Type-C/DP1.4a to MIPI or LVDS chip for VR/Display application.
HDCP RX as the upstream of HDCP repeater, can cooperate with HDCP TX of other chips to realize the repeater function.
For DP1.4a input, LT7911UXC can be configured as 1/2/4 lanes. Adaptive equalization makes it suitable for long cable application and the maximum bandwidth up to 32.4Gbps.
For MIPI output, LT7911UXC features configurable single-port or dual-port or quad-port MIPI®DSI/CSI with 1 high-speed clock lane and 1~4 high-speed data lanes operating at maximum 2.5Gbps/lane with D-PHY, which can support a total bandwidth of up to 40Gbps for four port. LT7911UX also support 5.7Gbps/lane with C-PHY, which can support a total bandwidth of up to 68.4Gbps for four port.
For LVDS output, LT7911UXC can be configured as single, dual or quad-port LVDS with 1 high-speed clock lane, and 3~5 high-speed data lanes, operating at maximum 1.2Gbps per lane, which can support a total bandwidth of up to 24Gbps. LT7911UXC supports flexible video data mapping path for 2D and 3D applications.
Two digital audio output interfaces are available I2S and SPDIF. The I2S interface supports 8-ch LPCM and the SPDIF interface supports 2-ch LPCM or compressed audio, both at maximum 192 KHz 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 configuration I2C slave interface.
LT7911UXC is fabricated in advanced CMOS process and implemented in 9mmx9mm BGA169 package.
