双通道无源开关MAX4888B/MAX4888C

     该MAX4888B/MAX4888C(2 ×双刀双掷)，高速无源开关是两个可能的目的地之间切换两个半的PCI Express?(PCIe)的数据通道的理想选择。这些器件具有双数字控制输入开关信号路径。该MAX4888C是为在那里的输入和输出电容耦合(如的SAS，SATA，XAUI和PCIe)和提供10μA(典型值)的源电流和60kΩ(典型值)的内部偏置电阻到地在系统中使用在AOUT_和BOUT_引脚。

　　该器件完全规定工作从单一的+ 3.3 V (典型值)电源。这两种设备都提供一个行业标准的3.5mm × 5.5mm的28引脚 TQFN 封装。他们工作在-40 ° C至+85 ° C扩展级温度范围。

　　关键特性

　　●+3.3 V单电源电压

　　●支持PCIe根余，第二代，第三和Gen率数据

　　●支持直至并包括6.0Gbps SAS / SATA的信号

　　●支持其他高速接口(例如，XAUI的)

　　●高带宽回波损耗

　　●3.5毫米×5.5毫米小型28引脚TQFN封装

　　The MAX4888B/MAX4888C dual double-pole/double-throw (2 x DPDT), high-speed passive switches are ideal for switching two half-lanes of PCI Express? (PCIe) data between two possible destinations. These devices feature a dual digital control input to switch signal paths. The MAX4888C is intended for use in systems where both the input and output are capacitively coupled (e.g., SAS, SATA, XAUI, and PCIe) and provides a 10?A (typ) source current and a 60kΩ (typ) internal biasing resistor to GND at the AOUT_ and BOUT_ pins.

　　The devices are fully specified to operate from a single +3.3V (typ) power supply. Both devices are available in an industry-standard 3.5mm x 5.5mm, 28-pin TQFN package. They operate over the -40°C to +85°C extended temperature range. Single +3.3V Power-Supply Voltage
