SGM7222
High Speed USB 2.0
(480Mbps) DPDT Analog Switch
GENERAL DESCRIPTION
FEATURES
The SGM7222 is a high-speed, low-power double-pole/
double-throw (DPDT) analog switch that operates from a
single 1.8V to 4.3V power supply.
SGM7222 is designed for the switching of high-speed
USB 2.0 signals in handset and consumer applications,
such as cell phones, digital cameras, and notebooks with
hubs or controllers with limited USB I/Os.
The SGM7222 has low bit-to-bit skew and high
channel-to-channel noise isolation, and is compatible with
various standards, such as high-speed USB 2.0 (480
Mbps). Each switch is bidirectional and offers little or no
attenuation of the high-speed signals at the outputs. Its
bandwidth is wide enough to pass high-speed USB 2.0
differential signals (480 Mb/s) with good signal integrity.
The SGM7222 contains special circuitry on the D+/D-
pins which allows the device to withstand a VBUS short to
D+ or D- when the USB devices are either powered off or
powered on.
SGM7222 is available in Green TQFN-1.8×1.4-10L,
MSOP-10 and UTQFN-1.8×1.4-10L packages. It operates
over an ambient temperature range of -40℃ to +85℃.
