Low Voltage Ultra Low Power

USB High Speed (480 Mbps) Dual DPDT Switch

General Description

FSUSB22 is a low power high bandwidth analog switch

specially designed for applications of the switching of high

speed USB 2.0 signals in handset and consumer applica-

tions such as cell phone, digital camera, and notebook with

hubs or controllers of limited USB I/O. The wide bandwidth

(750MHz) of this switch allows signals to pass with mini-

mum edge and phase distortion. Superior channel-to-chan-

nel

crosstalk

results

in

minimal

interference.

It

is

compatible with high speed USB2.0 standard.
