产品简介

CXAS42201是一款高速、低功耗的双极/双掷（DPDT）模拟开关，工作电压从1.8V到5.5V，可直接从USB接口的VBU供电。
CXAS42201专为手机和消费类应用（如手机、数码相机和带有集线器或控制器的笔记本电脑，USB I/O有限）中高速USB 2.0信号的交换而设计。
CXAS42201具有低位对位偏差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（480Mb/s）。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。
CXAS42201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。

•供电范围：1.8V至5.5V
•导通电阻：5Ω（典型值）
•由VBU直接供电
•D+/D-对VBUS保护短路
•快速切换时间：
t=15ns（典型值）
tOFF=20ns（典型值）
•串扰：250MHz时为-30dB
•关闭隔离：250MHz时为-35dB
•接通前断开开关

   产品概述 返回TOP

The CXAS42201 is a high-speed, low-power double-pole/ double-throw (DPDT) analog switch that operates from a single 1.8V to 5.5V power supply and it can be powered directly from VBUS of USB interface.

CXAS42201 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 CXAS42201 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 (480Mb/s). 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 (480Mb/s) with good signal integrity.

The CXAS42201 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.

CXAS42201 is available in Green TQFN-2.6×1.8-16L package. It operates over an ambient temperature range of -40℃ to +85℃.
