国产芯片LT7911UXE适用于Type-C/DP1.4a或HDMI2.1到MIPI或LVDS

LT7911UXE描述

1. Description

LT7911UXE is a high performance Type-C/DP1.4a or HDMI2.1 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 Type-C/DP1.4a input, LT7911UXE 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 HDMI2.1 input, LT7911UXE can be configured as 3/4 lanes. Adaptive equalization makes it suitable for long cable application and the maximum bandwidth up to 40Gbps.

For MIPI output, LT7911UXE 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, LT7911UXE 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. LT7911UXE 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. Package:BGA169-9*9.

1. 描述



LT7911UXE是一款高性能的Type-C/DP1.4a或HDMI2.1到MIPI或LVDS芯片，用于VR/显示应用。



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

对于Type-C/DP1.4a输入，LT7911UXE可配置为1/2/4通道。自适应均衡使其适用于长电缆应用，最大带宽高达32.4Gbps。

对于HDMI2.1输入，LT7911UXE可以配置为3/4通道。自适应均衡使其适用于长电缆应用，最大带宽高达40Gbps。

对于MIPI输出，LT7911UXE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，运行速度最高为2.5Gbps/lane，具有D-PHY，可支持四个端口的总带宽高达40Gbps。LT7911UX还支持5.7Gbps/lane的C-PHY，四个端口可支持高达68.4Gbps的总带宽。

对于LVDS输出，LT7911UXE可配置为单端口、双端口或四端口LVDS，具有1条高速时钟通道和3~5条高速数据通道，每条通道最大工作速度为1.2Gbps，可支持总带宽高达24Gbps。LT7911UXE支持灵活的2D和3D应用视频数据映射路径。

数字音频输出接口有I2S和SPDIF两种。I2S接口支持8-ch LPCM, SPDIF接口支持2-ch LPCM或压缩音频，最大采样率均为192 KHz。

该设备能够通过集成的微处理器实现自动操作，该微处理器使用嵌入式SPI闪存进行固件存储。系统控制也可通过配置I2C从接口。封装：BGA169-9*9
