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 (R_L= 50Ω, f = 250MHz)

● Low Crosstalk: -41dB (R_L= 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:

t_ON: 10ns (TYP)

t_OFF: 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 V_BUSshort 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℃.
