FN6515.0

MP3/USB 2.0 High Speed Switch with

Negative Signal Handling

Features

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

Signaling Capability per USB 2.0

The Intersil ISL54206A dual SPDT (Single Pole/Double

Throw) switches combine low distortion audio and accurate

USB 2.0 high speed data (480Mbps) signal switching in the

same low voltage device. When operated with a 2.7V to 3.6V

single supply these analog switches allow audio signal

swings below-ground, allowing the use of a common USB

and audio headphone connector in Personal Media Players

and other portable battery powered devices.

• Low Distortion Negative Signal Capability

• Control Pin to Open all Switches and Enter Low Power

State

• Low Distortion Headphone Audio Signals

- THD+N at 20mW into 32Ω Load . . . . . . . . . . . . . <0.1%

• Cross-talk Audio Channels (20Hz to 20kHz) . . . . . -110dB

The ISL54206A logic control pins are 1.8V compatible which

allows for control via a standard µcontroller. With a VDD

voltage in the range of 2.7V to 3.6V the IN pin voltage can

exceed the VDD rail allowing for the USB 5V VBUS voltage

from a computer to directly drive the IN pin to switch

between the audio and USB signal sources in the portable

device. The part has an audio enable control pin to open all

the switches and put the part in a low power state.

• Single Supply Operation (V ) . . . . . . . . . . . . 2.5V to 5.5V

• -3dB Bandwidth USB Switches . . . . . . . . . . . . . . . 630MHz

• Available in µTQFN and TDFN Packages

• Pb-Free Plus Anneal (RoHS Compliant)

• Compliant with USB 2.0 Short Circuit Requirements

Without Additional External Components

The ISL54206A is available in a small 10 Ld 2.1mmx1.6mm

ultra-thin µTQFN package and a 10 Ld 3mmx3mm TDFN

package. It operates over a temperature range of -40 to

+85°C.

Applications

• MP3 and Other Personal Media Players

• Cellular/Mobile Phones

• PDA’s
