FSUSB20
Low Voltage Ultra Low Power
USB High Speed (480 Mbps) Dual DPDT Switch
(Preliminary)
General Description
Features
FSUSB20 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
( 720MHz) 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.
■
30dB OFF Isolation at 250MHz
■
30dB non-adjacent channel crosstalk at 250MHz
■ 4.5 typical On Resistance (RON
3dB bandwidth: 720MHz
)
■
■ Low power consumption (1uA max)
■ Control input: LVTTL compatible
■ Bidirectional operation
■ USB high speed and full speed signaling capability
Applications
•
Cell phone, PDA, digital camera, and notebook

Note 1: The Absolute Maximum Ratings are those values beyond which
the safety of the device cannot be guaranteed. The device should not be
operated at these limits. The parametric values defined in the Electrical
Characteristics tables are not guaranteed at the absolute maximum rating.
The Recommended Operating Conditions tables will define the conditions
for actual device operation.
