FSUSB30 Low Power 2-Port Hi-Speed USB 2.0 (480Mbps) Switch General Description Features The FSUSB30 is a Low Power, 2-Port Hi-Speed USB 2.0 switch. This part is configured as a DPDT switch and is optimized for switching between two Hi-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 6.5pF. The wide bandwidth of this device (720MHz), exceeds the bandwidth needed to pass the 3rd harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk also minimizes interference. ■ Low On Capacitance, 6.5pF (typical) ■ Low On Resistance, 6.5Ω (typical) ■ Low power consumption (1µA maximum) ■ ■ ■ ■ The FSUSB30 contains special circuitry on the D+/Dpins which allows the device to withstand an overvoltage condition. 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 Ultra-Portable 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. – 10µA maximum ICCT over and 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 4.3V Packaged in: – Pb-Free 10-lead MicroPak™ (1.6mm x 2.1mm) – Pb-Free 14-lead DQFN – Pb-Free 10-lead MSOP (preliminary) Applications ■ Cell phone, PDA, Digital Camera, and Notebook ■ LCD Monitor, TV, and Set-top Box Ordering Information Order Number Package Number FSUSB30L10X MAC010A Pb-Free 10-Lead MicroPak, 1.6 mm x 2.1mm FSUSB30BQX MLP014A Pb-Free 14-Terminal Depopulated Quad Very-Thin Flat Pack No Leads (DQFN), JEDEC MO-241, 2.5 x 3.0mm FSUSB30MUX (Preliminary) MUA10A 10-Lead Molded Small Outline Package (MSOP), JEDEC MO-187, 3.0mm Wide Package Description Pb-Free package per JEDEC J-STD-020B.
