LT8631UX-3 HDMI TO 1 HDMI1.4/2.0/DVI 1.0 compliant
1一般說(shuō)明
LT8631UX是3端口HDMI/DVI交換機(jī),可將多個(gè)HDMI/DVI源設(shè)備連接到高清電視(HDTV)。基于ClearEdge? 技術(shù)方面,它符合HDMI 2.0/DVI 1.0規(guī)范。LT8631UX是一種的高速交換機(jī),它為制造商提供了一種經(jīng)濟(jì)高效的方法,可以為其HDTV添加額外的HDMI/DVI端口。多個(gè)HDMI/DVI端口允許消費(fèi)者將各種HDMI/DVI源連接到他們的HDTV。
LT8631UX是一個(gè)三對(duì)一(3:1)開(kāi)關(guān),非常適合用于HDTV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)。LT8631UX交換機(jī)從三個(gè)接收器端口選擇一個(gè)HDMI/DVI信號(hào),并生成完全兼容的HDMI//DVI音頻/視頻輸出,以及完全符合HDMI/DVI規(guī)范的DDC和HPD切換。
該芯片還集成了RX側(cè)芯片終端(ODT),并采用了ODT管理電路,以實(shí)現(xiàn)經(jīng)濟(jì)高效的系統(tǒng)設(shè)計(jì)和增強(qiáng)的性能。集成的DDC和HPD交換機(jī)進(jìn)一步降低了系統(tǒng)制造成本,并簡(jiǎn)化了主板上的布線。
