UM7222A QFN10 2.1×1.6
General Description
The UM7222MA/UM7222/UM7222A is a dual port high-speed, low-power data switch optimized
for USB 2.0 signal switching. The UM7222MA/UM7222/UM7222A switch is configured in
double-pole/ double-throw DPDT. It handles bidirectional signal flow, achieving a 550 MHz -3dB
bandwidth, and a port to port crosstalk and isolation at -50dB at 250MHz.
The UM7222MA/UM7222/UM7222A operates from a single +2.7V to +5.5V supply, with
current consumption less than 1 microampere.
The UM7222MA/UM7222/UM7222A features wide bandwidth and low bit-to-bit skew allow it to
pass high-speed differential signal with good signal integrity, offers little or no attenuation of the
high-speed signals at the outputs. Its high channel-to-channel crosstalk rejection results in
minimal noise interface. Its bandwidth is wide enough to pass high-speed USB 2.0 differential
signals (480Mbps). The control logic threshold is guaranteed to be compatible with 1.8V logic.
The UM7222MA is available in Pb-free MSOP10 package, the UM7222 is available in Pb-free
QFN10 package (1.4mm×1.8mm×0.55mm), while the UM7222A is available in Pb-free QFN10
package (2.1mm×1.6mm×0.55mm), they are ideal for portable high speed mix signal switching
application.

Applications Information
Power-Off Protection
For a VBUS short circuit, the switch is expected to withstand such a condition for at least 24
hours. The UM7222 has specially designed circuitry which prevents unintended signal bleed
through as well as guaranteed system reliability during a power-down, over-voltage condition.
The protection has been added to the common pins (D+, D-).
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. This modification works by limiting current flow back
into the V+ 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.
