品牌詳情
龍訊LT8311EX高性能USB中繼器延伸長(zhǎng)度達(dá)120米
1. 一般的描述
LT8311EX是一款低成本的高性能USB中繼器,支持通過(guò)cat5/5e/6電纜進(jìn)行信號(hào)傳輸擴(kuò)展,符合USB2.0規(guī)范。 延伸長(zhǎng)度可達(dá)120米以上的CAT6電纜。 它消除了USB2.0規(guī)格5米距離的限制。 兩個(gè)LT8311EX芯片之間有四條線(xiàn)用于信號(hào)傳輸擴(kuò)展。 內(nèi)部均衡設(shè)置可以通過(guò)I2C接口改變不同的擴(kuò)展長(zhǎng)度。
2. 特性
?延伸長(zhǎng)度達(dá)120米
?支持usb2.0高速和usb1.1(低速和全速)
?支持熱插拔
?內(nèi)部上拉和下拉電阻
?引腳控制和I2C控制模式均衡
?單路3.3V電源
?20針TSSOP RoHS封裝
?-40 ~ 85℃工作溫度范圍
?ESD:HBM到2KV
3. 應(yīng)用程序
?臺(tái)式機(jī)和筆記本電腦,擴(kuò)展塢
?服務(wù)器和工作站
?數(shù)據(jù)存儲(chǔ)系統(tǒng)
1. General Description
LT8311EX is a low cost high performance USB repeater that supports signal transferring extension over cat5/5e/6 cable, compliant with USB2.0 specification. The extension length can be up to 120 meters over CAT6 cable. It eliminates the 5 meters distance limitation of USB2.0 specification. There are four lines used for signal transferring extension between two LT8311EX chips. Internal equalization settings can be changed through I2C interface for different extension lengths.
2. Features
? Extension length up to 120 meters
? Support USB 2.0 high-speed and USB 1.1(low-speed and full-speed)
? Support hot plugg
? Internal pull-up and pull-down resistor
? Pin control and I2C control mode for equalization
? Single 3.3V power supply
? 20-pin TSSOP RoHS package
? -40 to 85℃ operating temperature range
? ESD:HBM to 2KV
3.APPLICATIONS
? Desktop and laptop computers, docking stations
? Servers and workstations
? Data storage systems
