ISL54210
MP3/USB 2.0 High Speed Switch with Negative Signal Handling/Click and Pop Suppression
FN6661 Rev 2.00 March 18, 2010
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 belowground, allowing the use of a common USB and audio headphone connector in Personal Media Players and other portable battery powered devices.
The ISL54210 incorporates circuitry for the detection of the USB VBUS voltage, which is used to switch between the audio and USB signal sources.
