FN6817.3

USB 2.0 High-Speed x 2Channels/Stereo

Audio Dual SP3T (Dual 3-to-1 Multiplexer)

Features

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

Signaling Capability per USB 2.0

The Intersil ISL54217 is a single supply dual SP3T analog

switch that operates from a single supply in the range of 2.7V

to 4.6V. It was designed to multiplex between audio stereo

signals and two different USB 2.0 high speed differential data

signals. The audio channels allow signal swings below

ground, allowing the multiplexing of voice and data signals

through a common headphone connector in Personal Media

Players and other portable battery powered devices.

• Low Distortion Negative Signal Capability Audio Switches

• Clickless/Popless Audio Switches

• Power OFF Protection

• COM Pins Overvoltage Tolerant to 5.5V

• Low Distortion Headphone Audio Signals

- THD+N at 5mW into 32Ω Load . . . . . . . . . . . . . <0.03%

The audio switch cells can pass ±1V ground referenced audio

signals with very low distortion (<0.03% THD+N when driving

5mW into 32Ω loads). The USB switch cells have very low

ON-capacitance (8pF) and high bandwidth to pass USB high

speed signals (480Mbps) with minimal edge and phase

distortion.

• Crosstalk (100kHz) . . . . . . . . . . . . . . . . . . . . . . . . . -98dB

• OFF-Isolation (100kHz) . . . . . . . . . . . . . . . . . . . . . 95.5dB

• Single Supply Operation (V ) . . . . . . . . . . . . 2.7V to 4.6V

• -3dB Bandwidth USB Switches . . . . . . . . . . . . . . . 700MHz

• Available in Tiny 12 Ld µTQFN and TQFN Packages

The ISL54217 is available in a tiny 12 Ld 2.2mmx1.4mm ultra

thin QFN and a 12 Ld 3mmx3mm TQFN package. It operates

over a temperature range of -40°C to +85°C.

• Compliant with USB 2.0 Short Circuit Requirements

Without Additional External Components

• Pb-Free (RoHS Compliant)

• Technical Brief TB363 “Guidelines for Handling and

Processing Moisture Sensitive Surface Mount Devices

(SMDs)”

Applications

• MP3 and other Personal Media Players

• Cellular/Mobile Phone
