Aimed at applications such as cell phones, PDAs, digital cameras, notebook / LCD monitors, TVs, and STBs, Fairchild's FSUSB43 2-port USB 2.0 switch is now available from Mouser stock. The bi-directional, low-power, two-port, high-speed, USB2.0 device is configured as a double-pole, double-throw (DPDT) switch. It is optimized for switching between two high-speed (480Mbps) sources or a high-speed and full-speed (12Mbps) source. The FSUSB43 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (CON) of 3.7pF. The wide bandwidth of this device (720MHz) exceeds the bandwidth needed to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk also minimizes interference, says the company.
