FSUSB30 Low-Power, Two-Port, High-Speed USB 2.0 (480Mbps) Switch Features ■ ■ ■ ■ ■ ■ ■ Description Low On Capacitance: 3.7pF (Typical) Low On Resistance: 6.5Ω (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 5.5V Packaged in: – 10-lead MicroPak™ (1.6 x 2.1mm) – 14-lead DQFN – 10-lead MSOP – 10-lead UMLP (1.4 x 1.8mm) 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 FullSpeed (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.

Channel Off Capacitance www.fairchildsemi.com 9 Power-On Protection In section 7.1.1 of the USB 2.0 specification, it notes that USB devices must be able to withstand a Vbus short to D+ or D- when the USB devices is either powered off or powered on. The FSUSB30 can be successfully configured to meet both these requirements. The USB 2.0 specification also notes that the USB device should be capable of withstanding a Vbus short during transmission of data. Fairchild recommends adding a 100Ω series resister between the switch VCC pin and supply rail to protect against this case. This modification works by limiting current flow back into the VCC rail during the over-voltage event so current remains within the safe operating range. In this application, the switch passes the full 5.25V input signal through to the selected output, while maintaining specified off isolation on the un-selected pins. Power-Off Protection For a Vbus short circuit, the switch is expected to withstand such a condition for at least 24 hours. The FSUSB30 has specially designed circuitry which prevents unintended signal bleed through as well as guaranteed system reliability during a power-down, overvoltage condition. The protection has been added to the common pins (D+, D-). VCC= 3.6 V 100 Ohms HSD+ HSD+ HSD- D+ = 5.25V FSUSB30 HSD- D- = 5.25V Figure 17. Adding 100Ω resistor in series with the VCC supply allows the FSUSB30 to withstand a Vbus short when powered up For more information, see Applications Note AN-6022 Using the FSUSB30 to Comply with USB 2.0 Fault Condition Requirements at www.fairchildsemi.com © 2006 Fairchild Semiconductor Corporation FSUSB30 Rev. 1.1.6 www.fairchildsemi.com 10 FSUSB30 Low-Power, Two-Port, High-Speed USB 2.0 (480Mbps) Switch Application Guidance: Meeting USB 2.0 Vbus Short Requirements Tape Format for DQFN Package Designator Tape Section Number Cavities Cavity Status Cover Tape Status Leader (Start End) 125 (typ) Empty Sealed Carrier 2500/3000 Filled Sealed Trailer (Hub End) 75 (typ) Empty Sealed BQX Tape Dimensions Dimenions are in millimeters unless otherwise specified. © 2006 Fairchild Semiconductor Corporation FSUSB30 Rev. 1.1.6 www.fairchildsemi.com 11 FSUSB30 Low-Power, Two-Port, High-Speed USB 2.0 (480Mbps) Switch Tape and Reel Specifications Dimensions are in inches (millimeters) unless otherwise specified.
