SGM7223
High Speed USB 2.0
(480Mbps) DPDT Analog Switch
GENERAL DESCRIPTION
The SGM7223 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.
SGM7223 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 SGM7223 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.
FEATURES
z RON is Typically 4.5Ω at 3.0V
z Low Bit-to-Bit Skew: 50ps (TYP)
z Voltage Operation: 1.8V to 4.3V
z Fast Switching Times:
tON 11ns
tOFF 20ns
z Low Crosstalk: -33dB at 250MHz
z Power-Off Protection when V+ = 0V,
D+/D- Pins can Tolerate up to 5.25V
z High Off-Isolation: -30dB at 250MHz
z Rail-to-Rail Input and Output Operation
z Break-Before-Make Switching
z Extended Industrial Temperature Range:
-40℃ to +85℃
z Available in Green TQFN-2.1×1.6-10L Package
The SGM7223 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.
SGM7223 is available in Green TQFN-2.1×1.6-10L
package. It operates over an ambient temperature range
of -40℃ to +85℃.
