MP3/USB 2.0 High Speed Switch with Negative

Signal Handling/Click and Pop Suppression

ISL54210

Features

The Intersil ISL54210 dual SPDT (Single Pole/Double

Throw) switch combines 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.

It has an enable pin (CTRL) to open all switches and

activate the audio click/pop (C/P) circuitry. The high

off-isolation and special C/P circuitry of the audio

switches eliminates click and pops in the head-phones

when the audio CODEC drivers are powering up/down

or when a headphone is inserted or removed from the

jack.
