CXDS4222Q是一种双向、低功耗、高速3:1开关，可从一个+2.3V到+5.5V的电源供电。
CXDS4222Q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1.8GHz）信号的切换而设计。
CXDS4222Q具有低比特对比特倾斜和高信道对信道噪声隔离，并且兼容各种标准，例如高速USB 2.0（480Mbps）、MHL 1080p/60fps。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（3.6Gbps）来说非常有限。CXDS4222Q在QFN1818-12L包中提供。标准产品无铅无卤。
电源电压：2.3~5.5V
•3dB带宽：1.8GHz@CL=0pF
关闭隔离：-57dB@50MHz
•串扰：-57dB@50MHz
低静态电流：60uA类型

产品概述 返回TOP
The CXDS4222Q is a bi-directional, low power, high-speed 3:1 switch that operates from a single +2.3V to +5.5V power supply.
The CXDS4222Q is designed for switching of high-speed (-3dB bandwidth 1.8GHz) signals in handset and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os.
The CXDS4222Q 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 1080p/60fps. 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 (3.6Gbps) with good signal integrity.
The CXDS4222Q is available in QFN1818-12L package. Standard products are Pb-Free and halogen-Free.
