SGM7223 High Speed USB 2.0(480Mbps) DPDT Analog Switch (2008/8/20)

发布时间:2008/8/20 11:18:10
    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 (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 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 Pb-free TQFN-10 (2.1mm× 1.6mm) package. It operates over an ambient temperature range of -40℃ to +85℃.
