FSUSB30 Low-Power 2-Port Hi-Speed USB 2.0 (480Mbps) Switch January 2007 FSUSB30 Low-Power 2-Port Hi-Speed USB 2.0 (480Mbps) Switch Features ■ ■ ■ 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 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, 6.5Ohm (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 Packaged in: – Pb-Free 10-lead MicroPak™ (1.6 x 2.1mm) – Pb-Free 14-lead DQFN – Pb-Free 10-lead MSOP – Pb-Free 10-lead UMLP (1.4 x 1.8mm) Applications ■ Cell phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-top Box Related Application Notes ■ AN-6022 Using the FSUSB30 / FSUSB31 to Comply with USB 2.0 Fault Condition Requirements Ordering Information Order Number FSUSB30L10X FSUSB30BQX FSUSB30MUX FSUSB30UMX Package Number MAC010A MLP014A MUA10A MLP010A Product Code Top Mark FJ USB30 FSUSB30 GJ Pb-Free Yes Yes Yes Yes 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 Pb-Free package per JEDEC J-STD-020B.
