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.
