FN6835.0

High-Speed USB 2.0 (480Mbps)

Multiplexer

Features

• High-Speed (480Mbps) and Full-Speed (12Mbps)

Signaling Capability per USB 2.0

The Intersil ISL54222 is a single supply dual 2:1 multiplexer

that can operate from a single 1.8V to 3.3V supply. It contains

two SPDT (Single Pole/Double Throw) switches configured as

a DPDT. The part was designed for switching or routing of

USB High-Speed signals and/or USB Full-speed signals in

portable battery powered products.

• 1.8V Logic Compatible

• Enable Pin to Open all Switches

• Power OFF Protection

• D-/D+ Pins are Overvoltage Tolerant to 5.5V

• -3dB Frequency . . . . . . . . . . . . . . . . . . . . . . . . . . 782MHz

• Low ON Capacitance. . . . . . . . . . . . . . . . . . . . . . . . 6.5pF

• Low ON-Resistance. . . . . . . . . . . . . . . . . . . . . . . . . . 5.5Ω

The 5.5Ω switches can swing rail-to-rail and were specifically

designed to pass USB full speed data signals that range from

0V to 3.3V and USB high speed data signals that range from

0V to 400mV with a single supply as low as 1.8V. They have

high bandwidth and low capacitance to pass USB high speed

data signals with minimal distortion.

• Single Supply Operation (V ) . . . . . . . . . . . . 1.8V to 3.3V

• Available in µTQFN, TDFN, and MSOP Packages

• Pb-Free (RoHS Compliant)

The part can be used in Personal Media Players and other

portable battery powered devices that need to route USB

high-speed signals and/or full-speed signals to different

transceiver sections of the device while connected to a single

USB host (computer).

• Compliant with USB 2.0 Short Circuit and Overvoltage

Requirements Without Additional External Components

Applications

The digital logic inputs are 1.8V logic compatible when

operated with a 1.8V to 3.3V supply. The ISL54222 has an

output enable pin to open all the switches. It can be used to

facilitate proper bus disconnect and connection when

switching between the USB sources.

• MP3 and other Personal Media Players

• Cellular/Mobile Phones

• PDA’s

The ISL54222 is available in 10 Ld 1.8mmx1.4mm µTQFN,

10 Ld TDFN and 10 Ld MSOP packages. It operates over a

temperature range of -40 to +85°C.

• Digital Cameras and Camcorders

• USB Switching
