FAIRCHILD FSUSB20_12

FSUSB20 — Low-Power, 1-Port, High-Speed USB
(480Mbps) Switch
Features
 -30dB Off Isolation: 250MHz
 -30dB Non-adjacent Channel Crosstalk: 250MHz
 On Resistance: 4.5Ω Typical (RON)
 -3dB Bandwidth: >720MHz
 Low-Power Consumption: 1µA Maximum
 Control Input: LVTTL Compatible
 Bi-Directional Operation
 USB High-Speed and Full-Speed Signaling
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 phone, digital camera, and notebook with hubs or
controllers of limited USB I/O. The wide bandwidth
(>720MHz) allows signals to pass with minimum edge
and phase distortion. Superior channel-to-channel
crosstalk results in minimal interference. It is compatible
with the high-speed USB 2.0 standard.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be
operable above the recommended operating conditions and stressing the parts to these levels is not recommended.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

3. Measured by the voltage drop between the A and B pins at the indicated current through the switch. On
resistance is determined by the lower of the voltages on the A or B pins.
4. Flatness is defines as the difference between the maximum and the minimum value on resistance over the
specified range of conditions.
