龍訊LT8311X高性能USB中繼器描述
1. 一般的描述
LT8311X是一款低成本的高性能USB中繼器,通過USB線纜提供信號(hào)傳輸擴(kuò)展,符合USB2.0規(guī)范,支持USB2.0、USB1.1和USB1.0設(shè)備連接。最大延伸長(zhǎng)度可達(dá)20米,從位置的USB集線器/主機(jī)通過USB電纜。它消除了USB2.0規(guī)格5米距離的限制。只有2條線用于兩個(gè)LT8311X芯片之間的數(shù)據(jù)傳輸。內(nèi)部均衡可以改變不同的寄存器設(shè)置。
2. 特性
•延伸長(zhǎng)度可達(dá)20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
•I2C控制模式均衡
•單路3.3V電源
•20pin TSSOP RoHS封裝和qfn16 RoHS封裝
•工作溫度范圍-40°C至85°C
•2線數(shù)據(jù)傳輸
•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)
•高密度介質(zhì)和智能監(jiān)控系統(tǒng)
1. General Description
LT8311X is a low cost high performance USB repeater that provides signal transferring extension over USB cable, compliant with USB2.0 specification, supports USB2.0, USB1.1 and USB1.0 device connection. The maximum extension length can be up to 20 meters from the location of USB hub/host over USB cable. It eliminates the 5 meters distance limitation of USB2.0 Specification. There are only 2 lines used for data transferring between two LT8311X chips. Internal equalization can be changed by different register settings.
2. Features
• Extension length up to 20 meters
• Support USB 2.0 high-speed and USB 1.1(low-speed and full-speed)
• Support hot plug
• Internal pull-up and pull-down resistor
• I2C control mode for equalization
• Single 3.3V power supply
• 20pin TSSOP RoHS package and QFN 16 RoHS package
• -40°C to 85°C operating temperature range
• 2 lines data transferring
• ESD:HBM to 2KV
3. APPLICATIONS
• Desktop and laptop computers, docking stations
• Servers and workstations
• Data storage systems
• High density media and intelligent monitoring system
