SGM7223

GENERAL DESCRIPTION

The SGM7223 is a high-speed, low-power double-pole/double-throw (DPDT) analog switch that operates from a single 1.8V to 4.3V power supply.

The SGM7223 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 SGM7223 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). 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 (480Mbps) with good signal integrity.

The SGM7223 contains special circuitry on the D+/D- pins which allows the device to withstand a VBUS short to D+ or D- when the USB devices are either powered off or powered on.

The SGM7223 is available in a Green TQFN-2.1×1.6-10L package. It operates over an ambient temperature range of -40 to +85.
