| FSUSB22 -- Low-Power, 2-Port, High-Speed USB 2.0 (480Mbps) Switch March 2008 FSUSB22 -- Low-Power, 2-Port, High-Speed USB 2.0 (480Mbps) Switch Features -40dB Off Isolation at 250MHz -40dB Non-adjacent Channel Crosstalk at 250MHz On Resistance: 4.5 Typical (RON) -3dB Bandwidth: 750MHz Low-Power Consumption: 1A Maximum Control Input: TTL Compatible Bi-directional Operation USB High-Speed and Full-Speed Signaling Capability Description FSUSB22 is a low-power, high-bandwidth switch specially designed for applications switching high-speed USB 2.0 signals in handset and consumer applications; such as cell phone, digital camera, and notebook with hubs or controllers of limited USB I/O. The wide bandwidth (750MHz) allows signals to pass with minimum edge and phase distortion. Superior channelto-channel crosstalk results in minimal interference. It is compatible with the USB2.0 Hi-Speed standard. .
