1. 描述

LT86121RXE-HDMI2.0中繼器，設(shè)計用于長電纜應(yīng)用。對于最長的電纜，應(yīng)該與LT86121TXE配套使用。在配對模式下，可以啟用幾個獨特的特性，以降低帶寬需求和優(yōu)化性能。

HDMI2.0的輸入和輸出都支持高達6Gbps的數(shù)據(jù)速率，這為4k@60Hz視頻提供了足夠的帶寬。數(shù)據(jù)加密也支持HDCP2.2。

在配對模式下，可以使用YCbCr4:1:1轉(zhuǎn)換和DSC解碼器來降低數(shù)據(jù)速率，從而降低帶寬要求。此外，可以激活FEC來糾正數(shù)據(jù)錯誤，幫助提高系統(tǒng)容錯水平。這些獨特的技術(shù)將顯著延長傳輸距離。

2ch到3ch的轉(zhuǎn)換消除了HDMI規(guī)格要求的3個差分數(shù)據(jù)對的必要。但數(shù)據(jù)速率將增加50%。在中、低帶寬的應(yīng)用中，2對數(shù)據(jù)就足夠了。

集成的USB中繼器支持高速、全速和低速模式。適用于USB信號擴展。還支持用戶自定義數(shù)據(jù)包，為邊帶數(shù)據(jù)通信提供了一條路徑。

該設(shè)備能夠自動操作，這是由一個集成的微處理器，使用嵌入式SPI閃存固件存儲。系統(tǒng)控制也可通過配置I2C從接口。

1. Description

The LT86121RXE is a high performance HDMI2.0 repeater designed for long cable application. It should be paired with LT86121TXE for longest cable reach. In paired mode, several unique features can be enabled to reduce bandwidth requirement and optimize performance.
Both the HDMI2.0 input and output support data rate up to 6Gbps which provides sufficient bandwidth for 4k@60Hz video. Also HDCP2.2 is supported for data encryption.
In paired mode, YCbCr4:1:1 conversion and DSC decoder can be used to reduce data rate and hence bandwidth requirement. Furthermore, FEC can be activated to correct data error and help to enhance system error tolerance level. These unique techniques together will significantly extend transmission distance.
2ch-to-3ch conversion eliminates the necessary of 3 differential data pairs as required by HDMI specification. But data rate will increase by 50%. In applications of low and middle bandwidth, 2 data pairs are enough for data transmission.
Integrated USB repeater supports high speed, full speed and low speed modes. It is suitable for USB signal extension. User defined packet is also supported which provides a path for sideband data communication.
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.
