CXAS42208允许将任何SD、SDIO和多媒体卡主机控制器扩展到多个卡或外围设备，因为SDIO接口由6位：CMD、CLK和数据[0:3]信号组成。CXAS42208有两个控制管脚，为用户提供了额外的灵活性。例如，在诸如液晶电视、液晶显示器或笔记本扩展底座等设备中对两个不同的音视频信号进行多路复用的能力。
•单电源范围：2.0V至5.0V
•低电容开关：15pF（典型）
•导通电阻：3V时为8.5Ω（典型值）
•-3dB带宽：450MHz
•低串扰：10MHz时为55dB
•高关隔离度：10MHz时为-57dB
•断电模式下的隔离，VCC=0V
•控制输入的1.8V逻辑阈值兼容性

产品概述 返回TOP
The CXAS42208 allows any SD, SDIO, and multimedia card host controllers to be expanded out to multiple cards or peripherals since the SDIO interface consists of 6-bits: CMD, CLK, and Data [0:3] signals. The CXAS42208 has two control pins that give additional flexibility to the user. For example, the ability to mux two different audio-video signals in equipment such as an LCD television, an LCD monitor, or a notebook docking station.
The CXAS42208 is available in Green TSSOP-24 and TQFN-4×4-24L packages. It operates over an ambient temperature range of -40℃ to+85℃.
