1. 一般的描述 LT86101SX是Lontium公司的第四代HDMI/DVI中继器，基于cleararedgeÔ技术，符合HDMI 1.3(高清晰度多媒体接口)规范。它是一个6.75Gbps (3 x 2.25Gbps)高性能重时钟设备，支持3个TMDS数据通道和一个单一的时钟通道。该设备还集成了一个双向DDC有源缓冲区和一个并行CEC有源缓冲区，以提供一个完整的HDMI/DVI中继器解决方案。 双控制模式可用于LT86101SX。这为系统设计人员提供了非常灵活的解决方案，以考虑性能或成本。LT86101SX支持两种控制模式:引脚控制模式和I2C控制模式。在引脚控制模式下，不需要外部MCU，基本功能由引脚配置控制，但高级功能是默认设置。在I2C控制模式下，需要外部MCU，芯片完全由MCU控制，控制引脚配置不再有效。 LT86101SX采用7mm x 7mm 48引脚QFN封装，工作温度范围为0°C至+70°C。 2. 特性 •兼容HDMI 1.3，支持2.25Gbps的数据速率 •支持3D视频格式和4Kx2K扩展分辨率格式 •自适应接收均衡高达40dB，以补偿长/便宜的电缆损耗 •odt和校准，更好的信号完整性 •单独的ODT电源交流耦合应用 •可配置传输去重，可达-9dB预补偿信号失真 •集成反向终端，提高输出信号质量 •容5v的有源DDC缓冲器允许电容高达3000pF •并行有源CEC缓冲器，驱动能力高达3000pF •扩展电缆长度如下:(rx面+ tx面) 高达(55m + 20m)超过26 AWG STP HDMI电缆@ 1.65Gbps 最大(35m + 20m)，超过26 AWG STP HDMI电缆@ 2.25Gbps 高达(25m + 15m)超过28awg STP HDMI电缆@ 1.65Gbps 高达(15m + 10m)超过28awg STP HDMI电缆@ 2.25Gbps •可级联，进一步延伸电缆 •双控制模式灵活应用 •链路活动检测，以启用抑制选项 •0.75W典型功耗 •ESD额定值:HBM±6kV •7mm x 7mm 48pin QFN无铅封装 3.应用程序 •TMDS电缆均衡器 •高清电视和显示器 •DVI/HDMI电缆扩展模块 •电缆组件 1. General Description LT86101SX is Lontium’s 4th generation HDMI/DVI repeater based on ClearEdgeÔ technology, compliant with the HDMI 1.3 (High Definition Multimedia Interface) specification. It is a 6.75Gbps (3 x 2.25Gbps) high performance re-clocking device that supports 3 TMDS data channels and a single clock channel. The device also integrates a bi-directional DDC active buffer and a parallel CEC active buffer to provide a complete HDMI/DVI repeater solution.
Dual control modes are available for LT86101SX. This provides system designers with very flexible solutions, for consideration of either performance or cost. The LT86101SX supports two control modes: Pin Control Mode and I2C Control Mode. In Pin Control Mode, no external MCU is needed, and the basic functions are under control of pin configurations, however advanced functions are at default settings. In I2C Control Mode, an external MCU is required, and the chip is fully controlled by MCU while the control pin configurations are not valid any more.
The LT86101SX is offered in a 7mm x 7mm 48-lead QFN package, and operates over a 0°C to +70°C temperature range.
