FSUSB42 — Low-Power, Two-Port, High-Speed, USB2.0 (480Mbps) UART Switch Features Description Low On Capacitance: 3.7 pF Typical Low On Resistance: 3.9 Ω Typical Low Power Consumption: 1 μA Maximum - 15 μA Maximum ICCT over an Expanded Voltage Range (VIN=1.8 V, VCC=4.4 V) Wide -3 db Bandwidth: > 720 MHz Packaged in: - 10-Lead UMLP (1.4 x 1.8 mm) - 10-Lead MSOP 8 kV ESD Rating, >16 kV Power / GND ESD Rating Over-Voltage Tolerance (OVT) on all USB Ports Up to 5.25 V without External Components The FSUSB42 is a bi-directional, low-power, two-port, high-speed, USB2.0 switch. Configured as a doublepole, double-throw switch (DPDT) switch, it is optimized for switching between any combination of high-speed (480 Mbps) or Full-Speed (12 Mbps) sources. The FSUSB42 is compatible with the requirements of USB2.0 and features an extremely low on capacitance (CON) of 3.7 pF. The wide bandwidth of this device (720 MHz) 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. The FSUSB42 contains special circuitry on the switch I/O pins for applications where the VCC supply is powered-off (VCC=0 V), 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.
