| FSUSB20 Low-Power 1-Port High-Speed USB (480Mbps) Switch September 2006 FSUSB20 Low-Power 1-Port High-Speed USB (480Mbps) Switch Features -30dB off isolation at 250MHz -30dB non-adjacent channel crosstalk at 250MHz 4.5 typical on resistance (RON) -3dB bandwidth: >720MHz Low power consumption (1A max) Control input: LVTTL compatible Bi-directional operation USB high-speed and full-speed signaling capability Space-saving Pb-free packaging General Description FSUSB20 is a low-power high-bandwidth switch specially designed for switching high-speed USB 2.0 signals in handset and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers with limited USB I/Os. The wide bandwidth (>720MHz) of this switch allows signals to pass with minimum edge and phase distortion. Superior channel-tochannel crosstalk results in minimal interference. It is compatible with the high-speed USB 2.0 standard. Applications Cell phone, PDA, digital camera, and notebook Ordering Information Order Number Package Number PbFree Yes Yes Yes Top Mark EY USB20 Package Description 10-Lead MicroPakTM, 1.6 x 2.1mm 14-Terminal Depopulated Quad Very-Thin Flat Pack No Leads (DQFN), JEDEC MO-241, 2.5 x 3.0mm FSUSB20L10X MAC010A FSUSB20BQX MLP014A FSUSB20MUX MUA10A FSUSB20 10-Lead Molded Small Outline Package (MSOP), JEDEC MO187, 3.0mm Wide Pb-Free package per JEDEC J-STD-020B.
