FSUSB30UMX

Low-Power 2-Port Hi-Speed USB 2.0 (480Mbps) Switch

General Description
The FSUSB30 is a low-power, two-port, high-speed USB 2.0 switch. Configured as a double-pole double-throw
(DPDT) switch, it is optimized for switching between two high-speed (480Mbps) sources or a Hi-Speed and Full-
Speed (12Mbps) source. The FSUSB30 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 minimizes interference. The FSUSB30 contains special circuitry on the D+/Dpins
which allows the device to withstand an overvoltage condition when powered off. This device is also designed
to minimize current consumption even when the control voltage applied to the S pin, is lower than the supply voltage
(VCC). This feature is especially valuable to ultraportable applications such as cell phones, allowing for
direct interface with the general purpose I/Os of the baseband processor. Other applications include switching
and connector sharing in portable cell phones, PDAs, digital cameras, printers, and notebook computers.

Features
■ Low On Capacitance, 3.7pF (typical)
■ Low On Resistance, 6.5Ohm (typical)
■ Low power consumption (1μA maximum)
   – 10μA maximum ICCT over an expanded control voltage range (VIN = 2.6V, VCC = 4.3V)
■ Wide -3dB bandwidth, >720MHz
■ 8KV ESD protection
■ Power-Off protection when VCC = 0V; D+/D- pins can tolerate up to 5.25V
