CXAS42199是一种高速、低功耗双极/双掷（DPDT）模拟开关，可从单个1.8V到4.3V电源供电。
CXAS42199是专为手机和消费应用程序（如手机、数码相机和带有集线器或控制器的笔记本电脑，其USB I/o有限）中高速USB 2.0信号的交换而设计的。
CXAS42199具有低位对位倾斜和高通道对通道噪声隔离，并且兼容各种标准，例如高速USB 2.0（480mbps）。每个开关都是双向的，在输出端几乎不衰减高速信号。它的带宽足够宽，可以通过高速USB 2.0差分信号（480mb/s），具有良好的信号完整性。
CXAS42199在D+/D引脚上包含特殊电路，当USB设备断电或通电时，该电路允许设备承受对D+或D+短路的VBU。
•3.0V时，RON通常为4.5Ω
•低比特对比特倾斜：50ps（典型值）
•电压运行：1.8V至4.3V
•快速切换时间：t10ns 时间22ns
•低串扰：250MHz时为41dB
•当V+=0V时断电保护，
D+/D-引脚可承受高达5.25V的电压
•高隔离度：250MHz时为-35dB
•轨对轨输入和输出操作
•接通前断开开关

产品概述 返回TOP
The CXAS42199 is a high-speed, low-power double-pole/double-throw (DPDT) analog switch that operates from a single 1.8V to 4.3V power supply.
CXAS42199 is designed for the switching of high-speed USB 2.0 signals in handset and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os.
The CXAS42199 has low bit-to-bit skew and high channel-to-channel noise isolation, and is compatible with various standards, such as high-speed USB 2.0 (480 Mbps). Each switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. Its bandwidth is wide enough to pass high-speed USB 2.0 differential signals (480 Mb/s) with good signal integrity.
The CXAS42199 contains special circuitry on the D+/D pins which allows the device to withstand a VBUS short to D+ or D- when the USB devices are either powered off or powered on.
CXAS42199 is available in Green TQFN-1.8×1.4-10L, MSOP-10 and UTQFN-1.8×1.4-10L packages. It operates over an ambient temperature range of -40℃ to +85℃.
