CXDS4223Q是一个双向、低功耗、高速4:1开关，可从一个+2.3V到+5.5V电源供电。
CXDS4223Q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，其USB I/O有限）中高速（-3dB带宽1.2GHz）信号的切换而设计。
CXDS4223Q具有低位对位偏差和高通道对通道噪声隔离，并兼容各种标准，如高速USB 2.0（480Mbps）、MHL视频720p/60fps和1080i/30fps。每个开关都是双向的，在输出端几乎不衰减高速信号。它的带宽对于通过具有良好信号完整性的高速差分信号（2.4Gbps）来说是非常有限的。CXDS4223Q具有D+/D-上的特殊电路，当USB设备断电或打开时，该电路允许设备承受对D+或D+短路的VBU。
CXDS4223Q在QFN1826-16L包中提供。标准产品无铅无卤。
电源电压：2.3~5.5V
•3dB带宽：1.2GHz@CL=0pF
关闭隔离：250MHz时为-50dB
l串扰：250MHz时为30dB
低静态电流：典型60uA

一.产品概述
The CXDS4223Q is a bi-directional, low power, high-speed 4:1 switch that operates from a single +2.3V to +5.5V power supply.
The CXDS4223Q is designed for switching of high-speed (-3dB bandwidth 1.2GHz) signals in handset and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os.
The CXDS4223Q 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 (480Mbps), MHL video 720p/60fps and 1080i/30fps. Each switch is bi-directional and offers little attenuation of the high-speed signals at the outputs. Its bandwidth is quite marginal to pass high-speed differential signals (2.4Gbps) with good signal integrity.
The CXDS4223Q is featured with special circuitry on the D+/D-, which allows the device to withstand a VBUS short to D+ or D- when the USB devices are either powered off or on.
The CXDS4223Q is available in QFN1826-16L package. Standard products are Pb-Free and halogen-Free.
