The CLCUSB30 is optimized for switching 480Mbps (USB2.0) signals in portable devices such as cell phones, digital cameras, PDAs, and notebook computers. The CLCUSB30 offers superior crosstalk (-45dB) and off-isolation (-30dB) to reduce channel-to-channel interference and provide good signal integrity. The low on-channel resistance and capacitance reduce attenuation and distortion during bi-directional HS signal routing. The CLCUSB30 also features protection circuitry on D+ and D- pins that allows the switch to handle overvoltage conditions when powered on or off.
