FSUSB23 — High-Speed, USB2.0 (480Mbps) Switch April 2008 FSUSB23 — High-Speed, USB2.0 (480Mbps) Switch Features 10µA Maximum ICCT Current over an Expanded Control Voltage Range: VIN = 2.6V, VCC = 3.6V) Lower Capacitance: CON = 9pF Typical 7Ω Typical On Resistance (RON) -3dB Bandwidth: > 720MHz Low Power Consumption: 1mA Maximum W ide -3db Bandwidth: > 720MHz Packaged in: Description The FSUSB23 is a low-power, high-bandwidth analog switch specifically designed for high speed USB 2.0 applications. The FSUSB23 features very low quiescent current even when the control voltage is lower than the VCC supply. This feature services mobile handset applications, allowing direct interface with the baseband processor general-purpose I/Os. Typical applications involve switching in portables and consumer applications, such as cell phones, digital cameras, and notebooks with hubs or controllers. The wide bandwidth (>720MHz) of this switch exceeds the bandwidth needed to pass the third harmonic, which results in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk results in minimal interference. - 10-Lead MicroPak™ (1.6 x 2.1mm) - 16-Lead DQFN (2.5 x3.5mm) 7kV I/O to GND ESD Performance Applications Cell phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-Top Box Ordering Information Part Number FSUSB23L10X FSUSB23BQX Top Mark EZ USB23 Operating Temperature Range -40 to +85°C -40 to +85°C Package 10-Lead MicroPak™ 1.6 x 2.1mm, JEDEC MO-255B 16-Terminal Depopulated Quad Very-Thin Flat Pack No Leads (DQFN), JEDEC MO-241, 2.5 x 3.5mm MicroPak™ is a trademark of Fairchild Semiconductor Corporation.
