The SGM7222 is a high-speed, low-power double-pole/double-throw (DPDT) analog switch that operates from asingle 1.8V to 4.3V power supply.

SGM7222 is designed for the switching of high-speed USB 2.0 signals in handset and consumer applications,such as cell phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os.

The SGM7222 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 (480 Mbps). Each switch is bidirectional and offers little or no attenuation of the high-speed signals at the outputs. Its bandwidth is wide enough to pass high-speed USB 2.0 differential signals (480 Mb/s) with good signal integrity.

The SGM7222 contains special circuitry on the D+/Dpins which allows the device to withstand a VBUS short to D+ or D- when the USB devices are either powered off or powered on.
