FSUSB30
Low-Power 2-Port Hi-Speed USB 2.0 (480Mbps) Switch
Features
General Description
■ Low On Capacitance, 3.7pF (typical)
■ Low On Resistance, 6.5Ohm (typical)
■ Low power consumption (1µA maximum)
– 10µA maximum ICCT over an expanded control
voltage range (VIN = 2.6V, VCC = 4.3V)
The FSUSB30 is a low-power, two-port, high-speed USB
2.0 switch. Configured as a double-pole double-throw
(DPDT) switch, it is optimized for switching between two
high-speed (480Mbps) sources or a Hi-Speed and Full-
Speed (12Mbps) source. The FSUSB30 is compatible
with the requirements of USB2.0 and features an
extremely low on capacitance (CON) of 3.7pF. The wide
bandwidth of this device (720MHz), exceeds the band-
width needed to pass the third harmonic, resulting in sig-
nals with minimum edge and phase distortion. Superior
channel-to-channel crosstalk minimizes interference.
■ Wide -3dB bandwidth, >720MHz
■ 8KV ESD protection
■ Power-Off protection when VCC = 0V; D+/D- pins can
tolerate up to 5.25V
■ Packaged in:
– Pb-Free 10-lead MicroPak™ (1.6 x 2.1mm)
– Pb-Free 14-lead DQFN
– Pb-Free 10-lead MSOP
The FSUSB30 contains special circuitry on the D+/D-
pins which allows the device to withstand an overvoltage
condition when powered off. This device is also designed
to minimize current consumption even when the control
voltage applied to the S pin, is lower than the supply volt-
age (VCC). This feature is especially valuable to ultra-
portable applications such as cell phones, allowing for
direct interface with the general purpose I/Os of the
baseband processor. Other applications include switch-
ing and connector sharing in portable cell phones, PDAs,
digital cameras, printers, and notebook computers.
– Pb-Free 10-lead UMLP (1.4 x 1.8mm)
Applications
■ Cell phone, PDA, Digital Camera, and Notebook LCD
Monitor, TV, and Set-top Box

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only.

Application Guidance: Meeting USB 2.0 Vbus Short Requirements
In section 7.1.1 of the USB 2.0 specification, it notes that
USB devices must be able to withstand a Vbus short to
D+ or D- when the USB devices is either powered off or
powered on. The FSUSB30 can be successfully config-
ured to meet both these requirements.
Power-On Protection
The USB 2.0 specification also notes that the USB
device should be capable of withstanding a Vbus short
during transmission of data. Fairchild recommends add-
ing a 100Ω series resister between the switch VCC pin
and supply rail to protect against this case. This modifi-
cation works by limiting current flow back into the VCC
rail during the over-voltage event so current remains
within the safe operating range. In this application, the
switch passes the full 5.25V input signal through to the
selected output, while maintaining specified off isolation
on the un-selected pins.
Power-Off Protection
For a Vbus short circuit, the switch is expected to with-
stand such a condition for at least 24 hours. The
FSUSB30 has specially designed circuitry which pre-
vents unintended signal bleed through as well as guar-
anteed system reliability during a power-down, over-
voltage condition. The protection has been added to the
common pins (D+, D-).
