简介
LT8668SXK8是一颗高性能的LCD Controller显示控制器芯片,它可配置输入DP1.4/HDMI2.1 , Type-C/DP1.4/HDMI2.1,audio in,配置输出LVDS/MIPI、eDP/eDPx,DP1.4/HDMI2.1、Audio out。
LT8668SXK8可配置为在HDMI2.1标准下工作,最大8Gbps数据速率。LT8668SXK8也可以配置为在DP1.4下工作,数据速率高达8.1Gbps。对于LVDS输出,LT8668SXK8 可以配置为单端口、双端口或四端口,具有1个高速时钟通道和3至5个高速数据通道,每个通道的最大工作速率为1.2Gbps,最高可支持24Gbps的总带宽。LT8668SXK8同样支持用于2D和并排3D应用程序的灵活视频数据映射路径。
对于MIPI输出,LT8668SXK8具有可配置的单端口或双端口或四端口MIPI®DSI/CSI,具有1条高速时钟通道和1至4条高速数据通道,每个通道的D-PHY最大工作速率为2.5Gbps,可支持四个端口的总带宽高达40Gbps。使用C-PHY还支持每通道5.7Gbps,四端口的总带宽可达68.4Gbps。
对于eDP输出,它由8条数据通道组成,支持RBR(1.62Gbps)、HBR(2.7Gbps)和HBR2(5.4Gbps)链路速度。内置可选SSC功能可减少EMI对EMI相关系统应用的影响。
对于eDPx输出,它由8个数据通道组成,每个通道的最大运行速度为3Gbps,可以支持4K@60Hz。
对于视频处理,内置LPDDR控制器,带宽高达3733Mbps,支持2Gb x16 SDRAM组织。有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,两者的最大采样率均为192 KHz。
该设备能够自动运行,由使用嵌入式SPI闪存进行固件存储的集成微处理器启用。系统控制也可通过配置I2C从接口进行。
LT8668SXK8采用先进的CMOS工艺制造,采用12mmx12mm BGA288封装实现。
