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/顯示應(yīng)用。
HDCP RX作為HDCP中繼器的上游,可以配合其他芯片的HDCP TX實(shí)現(xiàn)中繼器功能。 對(duì)于Type-C/DP1.4a輸入,LT7911UXE可配置為1/2/4通道。自適應(yīng)均衡使其適用于長(zhǎng)電纜應(yīng)用,最大帶寬高達(dá)32.4Gbps。
對(duì)于HDMI2.1輸入,LT7911UXE可以配置為3/4通道。自適應(yīng)均衡使其適用于長(zhǎng)電纜應(yīng)用,最大帶寬高達(dá)40Gbps。
對(duì)于MIPI輸出,LT7911UXE具有可配置的單端口或雙端口或四端口MIPI?DSI/CSI,具有1個(gè)高速時(shí)鐘通道和1~4個(gè)高速數(shù)據(jù)通道,運(yùn)行速度最高為2.5Gbps/lane,具有D-PHY,可支持四個(gè)端口的總帶寬高達(dá)40Gbps。LT7911UX還支持5.7Gbps/lane的C-PHY,四個(gè)端口可支持高達(dá)68.4Gbps的總帶寬。
對(duì)于LVDS輸出,LT7911UXE可配置為單端口、雙端口或四端口LVDS,具有1條高速時(shí)鐘通道和3~5條高速數(shù)據(jù)通道,每條通道最大工作速度為1.2Gbps,可支持總帶寬高達(dá)24Gbps。LT7911UXE支持靈活的2D和3D應(yīng)用視頻數(shù)據(jù)映射路徑。
數(shù)字音頻輸出接口有I2S和SPDIF兩種。I2S接口支持8-ch LPCM, SPDIF接口支持2-ch LPCM或壓縮音頻,最大采樣率均為192 KHz。
該設(shè)備能夠通過集成的微處理器實(shí)現(xiàn)自動(dòng)操作,該微處理器使用嵌入式SPI閃存進(jìn)行固件存儲(chǔ)。系統(tǒng)控制也可通過配置I2C從接口。

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.
