Data Sheet

December 18, 2006

FN6410.0

Low Voltage, Dual SPDT, USB/CVBS/

Audio Switches, with Negative Signal

Capability

Features

• High Speed (480Mbps) Signaling Capability per USB 2.0

• Low Distortion Negative Signal Capability

The Intersil ISL54208 dual SPDT (Single Pole/Double

Throw) switches combine low distortion audio/video and

accurate USB 2.0 high speed (480Mbps) data signal

switching in the same low voltage device. When operated

with a 2.7V to 3.6V single supply these analog switches

allow audio/video signal swings below-ground, allowing the

use of a common USB and audio/video connector in digital

cameras, camcorders and other portable battery powered

Personal Media Player devices.

• Control Pin to Open all Switches and Enter Low Power

State

• Low Distortion Mono Audio Signal

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

• Low Distortion Color Video Signal

- Differential Gain . . . . . . . . . . . . . . . . . . . . . . . . . . 0.28%

- Differential Phase. . . . . . . . . . . . . . . . . . . . . . . . . . 0.04°

• Cross-talk NCx Channels (4MHz) . . . . . . . . . . . . . . -78dB

The ISL54208 logic control pins are 1.8V logic compatible

which allows 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/video and USB signal sources in the

portable device. The part has an enable control pin to open

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

• Single Supply Operation (V ) . . . . . . . . . . . . 1.8V to 5.5V

• -3dB Bandwidth USB NOx 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 ISL54208 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

• Digital Camera and Camcorders

• Video MP3 and other Personal Media Players

• Cellular/Mobile Phones

• PDA’s
