The UM7222B is a high-speed, double-pole/ double-throw DPDT, low-power data switch optimized for USB 2.0 signal switching. The device multiplexes differential outputs from a USB host device to one of two corresponding outputs, or from two different hosts to one corresponding output. The switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. It handles bidirectional signal flow, achieving a 550 MHz -3dB bandwidth, and a port to port crosstalk and isolation at -50dB at 250MHz.
The UM7222B operates from a single 1.65V to 5.5V supply, with current consumption less than 1 μA. Its high channel-to-channel crosstalk rejection results in minimal noise interface. Its bandwidth is wide enough to pass high-speed USB 2.0 differential signals (480Mbps). The control logic threshold is guaranteed to be compatible with 1.8V logic.
The UM7222B is available in Pb-free QFN10 package (1.4mm×1.8mm×0.55mm). The device is ideal for handset and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os.
