LT8631SX是3端口HDMI/DVI開關(guān)

1. 一般的描述
LT8631SX是3端口HDMI/DVI開關(guān)，可以將多個(gè)HDMI/DVI源設(shè)備連接到高清電視(HDTV)?；赾leararedge技術(shù)，它符合HDMI 1.4/DVI 1.0規(guī)范。LT8631SX是一種先進(jìn)的高速開關(guān)，為制造商提供了一種經(jīng)濟(jì)有效的方法，為他們的HDTV添加額外的HDMI/DVI端口。多個(gè)HDMI/DVI端口允許消費(fèi)者連接各種HDMI/DVI源到他們的HDTV。
LT8631SX是一個(gè)3比1(3:1)的開關(guān)，非常適合用于高清電視和a /V接收器的后面板，允許消費(fèi)者連接多個(gè)HDMI/DVI設(shè)備，如高清DVD播放器，機(jī)頂盒和游戲機(jī)。LT8631SX交換機(jī)從三個(gè)接收端口選擇一個(gè)單一的HDMI/DVI信號(hào)，并產(chǎn)生完全兼容的HDMI//DVI音頻/視頻輸出，以及完全符合HDMI/DVI規(guī)格的DDC和HPD切換。
該芯片還集成了RX側(cè)模切終端(ODT)，并采用ODT管理電路，以提高系統(tǒng)設(shè)計(jì)的成本效益和性能。DDC與HPD交換機(jī)的集成進(jìn)一步降低了系統(tǒng)制造成本，簡(jiǎn)化了系統(tǒng)板上的布線。

1. General Description

The LT8631SX is 3-Port HDMI/DVI switch that enable the connection of multiple HDMI/DVI source devICes to high-definition television (HDTV). Based on ClearEdge? Technology, it is compliant with the HDMI 1.4/DVI 1.0 specifications. LT8631SX is an advanced high-speed switch that delivers a cost-effective method for manufacturers to add additional HDMI/DVI ports to their HDTV. Multiple HDMI/DVI ports allow consumers to connect variety HDMI/DVI sources to their HDTV.
The LT8631SX is a three-to-one (3:1) switch ideally suited for use in the back panel of HDTV and A/V receivers, allowing consumers to connect multiple HDMI/DVI devices such as high-definition DVD players, set top boxes and game consoles. The LT8631SX switch selects a single HDMI/DVI signal from the three receiver ports and generates fully compliant HDMI//DVI audio/video output, as well as DDC and HPD switching in full compliance with the HDMI/DVI specifications.
The chip also integrates RX side on-die-terminations (ODTs), and employs the ODT management circuitry for cost-efficient system design and enhanced performance.  The integrated DDC and HPD switches further lower the cost of system manufacture, and simplify the routing on the system board.
