雙通道無源開關MAX4888B/MAX4888C
英飛凌汽車電子生態(tài)圈
該MAX4888B/MAX4888C(2 ×雙刀雙擲)，高速無源開關是兩個可能的目的地之間切換兩個半的PCI Express?(PCIe)的數據通道的理想選擇。這些器件具有雙數字控制輸入開關信號路徑。該MAX4888C是為在那里的輸入和輸出電容耦合(如的SAS，SATA，XAUI和PCIe)和提供10μA(典型值)的源電流和60kΩ(典型值)的內部偏置電阻到地在系統(tǒng)中使用在AOUT_和BOUT_引腳。
該器件完全規(guī)定工作從單一的+ 3.3 V (典型值)電源。這兩種設備都提供一個行業(yè)標準的3.5mm × 5.5mm的28引腳 TQFN 封裝。他們工作在-40 ° C至+85 ° C擴展級溫度范圍。
關鍵特性
●+3.3 V單電源電壓
●支持PCIe根余，第二代，第三和Gen率數據
●支持直至并包括6.0Gbps SAS / SATA的信號
●支持其他高速接口(例如，XAUI的)
●高帶寬回波損耗
●3.5毫米×5.5毫米小型28引腳TQFN封裝
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
