FSUSB42 — Low-Power, Two-Port, Hi-Speed, USB2.0 (480Mbps) UART Switch Description Features The FSUSB42 is a bi-directional, low-power, two-port, Hi-Speed, USB2.0 switch. Configured as a double-pole, double-throw switch (DPDT) switch, it is optimized for switching between two Hi-Speed (480Mbps) sources or a Hi-Speed and Full-Speed (12Mbps) source. Low On Capacitance: 3.7pF Typical Low On Resistance: 3.9Ω Typical Low Power Consumption: 1μA Maximum - 15μA Maximum ICCT over an Expanded Voltage Range (VIN=1.8V, VCC=4.4V) Wide -3db Bandwidth: > 720MHz Packaged in: - 10-Lead UMLP (1.4 x 1.8mm) - 10-Lead MSOP 8kV ESD Rating, >16kV Power/GND ESD Rating Over-Voltage Tolerance (OVT) on all USB Ports Up to 5.25V without External Components The FSUSB42 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (CON) of 3.7pF. The wide bandwidth of this device (720MHz) exceeds the bandwidth needed to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk also minimizes interference. Applications Cell phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-Top Box IMPORTANT NOTE: For additional performance information, please contact [email protected]. The FSUSB42 contains special circuitry on the switch I/O pins for applications where the VCC supply is powered-off (VCC=0), which allows the device to withstand an over-voltage condition. This device is designed to minimize current consumption even when the control voltage applied to the SEL pin is lower than the supply voltage (VCC). This feature is especially valuable to ultra-portable applications, such as cell phones, allowing for direct interface with the generalpurpose I/Os of the baseband processor. Other applications include switching and connector sharing in portable cell phones, PDAs, digital cameras, printers, and notebook computers.
