龙讯LT86101SX-HDMI/DVI中继器描述

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。

1. General Description
LT86101SX is Lontium’s 4th generation HDMI/DVI repeater based on ClearEdge 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.
