High Speed USB 2.0 (480Mbps) DPDT Analog Switch High Speed USB 2.0 Double Pole Double Throw Analog Switch
Features
Product Name: High Speed USB 2.0 (480Mbps) DPDT Analog Switch
Product model: SGM7223
Product 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.
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 (480Mb/s) 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.
SGM7223 is available in Green TQFN-2.1×1.6-10L package. It operates over an ambient temperature range of -40°С to +85°С
