SGM7222
High Speed USB 2.0 (480Mbps)
DPDT Analog Switch
GENERAL DESCRIPTION
FEATURES
The SGM7222 is a DPDT (double-pole/double-throw)
analog switch. It operates from a 1.8V to 4.3V single
power supply. Each switch of the SGM7222 is
bidirectional, which can ensure that the high speed
signals have little or no attenuation at the outputs.
● Supply Voltage Range: 1.8V to 4.3V
● On-Resistance: 4.5Ω (TYP) at 3V
● High Off-Isolation: -35dB (RL = 50Ω, f = 250MHz)
● Low Crosstalk: -41dB (RL = 50Ω, f = 250MHz)
● Low Bit-to-Bit Skew: 50ps (TYP)
● -3dB Bandwidth: 550MHz
The SGM7222 features high speed, low bit-to-bit skew
and wide bandwidth. The high performances make it
very suitable for multiple applications, such as cellular
phones and computer peripherals, etc.
● Fast Switching Times:
tON: 10ns (TYP)
tOFF: 22ns (TYP)
● Break-Before-Make Switching
The SGM7222 has a power-off protection. It can
prevent accidental signal leakage and ensure system
reliability under power-down and over-voltage
conditions. In addition, the device is capable of
withstanding a VBUS short to D+ or D- when the device
is either powered on or powered off because of the
special circuitry on the D+/D- pins.
● Rail-to-Rail Input and Output Operation
● Power-Off and Power-On Protections
● -40℃ to +85℃ Operating Temperature Range
● Available in Green MSOP-10, TQFN-1.8×1.4-10L
and UTQFN-1.8×1.4-10L Packages
The 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℃.

This integrated circuit can be damaged if ESD protections are
not considered carefully. SGMICRO recommends that all
integrated circuits be handled with appropriate precautions.
Failure to observe proper handling and installation procedures
can cause damage. ESD damage can range from subtle
performance degradation tocomplete device failure. Precision
integrated circuits may be more susceptible to damage
because even small parametric changes could cause the
device not to meet the published specifications.

APPLICATION INFORMATION
Meet the Short Requirements of USB 2.0
VBUS
According to Section 7.1.1 of the USB 2.0 specification,
USB devices must be able to withstand a VBUS short to
D+ or D- when powered on or off. The SGM7222 can
fully meet these two requirements
Power-On Protection
The USB 2.0 specification requires USB device to
ensure that the device will not be damaged even if VBUS
short-circuit occurs during data transmission. Therefore,
under over-voltage conditions, the SGM7222 will limit
the current flowing back to the V+ track, and the current
will not exceed the safe operating range.
Power-Off Protection
USB2.0 Signal Quality Compliance Test
Results
The results of USB eye map test are shown in Figure 1
and Figure 2. Table 1 gives a summary of the USB
tests.
When D+ or D- is shorted to VBUS, there is a special
protection circuit inside the SGM7222, so that the
device will not be damaged within 24 hours. In case of
power-down or over-voltage event, the protection
circuit can prevent the leakage signal on D+/D- pins to
ensure the reliability of the system.
