FSUSB30 Low-Power, Two-Port, High-Speed USB 2.0 (480Mbps) Switch September 2008 FSUSB30 Low-Power, Two-Port, High-Speed USB 2.0 (480Mbps) Switch Features ■ ■ ■ 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 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. ■ ■ ■ ■ 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) Cell phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-top Box AN-6022 Using the FSUSB30 / FSUSB31 to Comply with USB 2.0 Fault Condition Requirements Applications ■ Related Application Notes ■ Ordering Information Order Number FSUSB30L10X FSUSB30BQX FSUSB30MUX FSUSB30UMX Package Number MAC010A MLP014A MUA10A MLP010A Product Code Top Mark FJ USB30 FSUSB30 GJ Eco Status RoHS Green Green Green Package Description 10-Lead MicroPak, 1.6 x 2.1mm 14-Terminal Depopulated Quad Very-Thin Flat Pack No Leads (DQFN), JEDEC MO-241, 2.5 x 3.0mm 10-Lead Molded Small Outline Package (MSOP), JEDEC MO-187, 3.0mm Wide 10-Lead, Quad, Ultrathin, MLP (UMLP) 1.4 x 1.8mm For Fairchild’s definition of “green” Eco Status, please visit: http://www.fairchildsemi.com/company/green/rohs_green.html. 1D+ USB2.0 Controller Set Top Box (STB) CPU or DSP Processor 1D– D– 2D+ DVR or Mass Storage 2D– Controller Control S OE VCC FSUSB30 D+ USB Connector Figure 1.

The FSUSB30 can be successfully configured to meet both these requirements. Power-On Protection 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+ HSDHSD- D+ = 5.25V FSUSB30 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 Tape and Reel Specifications Tape Format for DQFN Package Designator BQX Tape Section Leader (Start End) Carrier Trailer (Hub End) Number Cavities 125 (typ) 2500/3000 75 (typ) Cavity Status Empty Filled Empty Cover Tape Status Sealed Sealed Sealed 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 Reel Dimensions for DQFN Dimensions are in inches (millimeters) unless otherwise specified.
