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.

Without Additional External Components

It’s available in a tiny 10 Ld 1.8mmx1.4mm ultra-thin

µTQFN package and a 10 Ld 3mmx3mm TDFN package.

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

Audio Switches

Detailed Description

The two audio switches (L, R) are 2.5Ω switches that can

pass signals that swing below ground. Crosstalk between

the audio switches is <-100dB over the audio band.

These switches have excellent off-isolation >105dB over

the audio band with a 32Ω load.

The ISL54210 device is a dual single pole/double throw

(SPDT) analog switch that operates from a single DC

power supply in the range of 2.7V to 3.6V. It was

designed to function as a dual 2-to-1 multiplexer to

select between USB differential data signals and audio L

and R stereo signals. It comes in tiny µTQFN and TDFN

packages for use in MP3 players, PDAs, cellphones, and

other personal media players.

Over a signal range of ±1V (0.707V

) with

RMS

V

> 2.7V, these switches have an extremely low r

resistance variation. They can pass ground referenced

audio signals with very low distortion (<0.06% THD+N)

when delivering 15.6mW into a 32Ω headphone speaker

load. See Figures 16, 17, 18, and 19 THD+N in “Typical

Performance Curves” beginning on page 14.

The part consists of two 2.5Ω audio switches and two

5.5Ω USB switches. The audio switches can accept

signals that swing below ground. They were designed to

pass audio left and right stereo signals, that are ground

referenced, with minimal distortion. The USB switches

were designed to pass high-speed USB differential data

signals with minimal edge and phase distortion.

The audio drivers should be connected at the L and R

side of the switch (pins 5 and 6 for µTQFN, pins 6 and 7

for TDFN) and the speaker loads should be connected at

the COM side of the switch (pins 2 and 3 for µTQFN, pins

3 and 4 for TDFN).

The ISL54210 was specifically designed for MP3 players,

personal media players and cellphone applications that

need to combine the audio headphone jack and the USB

data connector into a single shared connector, thereby

saving space and component cost. A “Typical Application

Block Diagram” of this functionality is shown on page 11.

The audio switches have click and pop circuitry on the L

and R side that is activated when the V

voltage is ≤

floating. The ISL54210 should be put in this mode before

powering down or powering up of the audio CODEC

drivers. In this mode, both the audio and USB in-line

switches will be OFF and the audio click and pop circuitry

will be ON. The high off-isolation of the audio switches

along with the click and pop circuitry will isolate the

transients generated during power-up and power-down

of the audio CODECs from getting through to the

headphones, thus eliminating click and pop noise in the

headphones.

The ISL54210 incorporates circuitry for the detection of

the USB V

voltage, which is used to switch between

the audio CODEC drivers and USB transceiver of the MP3

player or cellphone. The ISL54210 contains a logic

control pin (CTRL) that when driven low while V

pop circuitry.

A detailed description of the two types of switches are

The two USB switches (D+, D-) are 5.5Ω bidirectional

CODECs drivers, the ISL54210 should be put in the Mute

and pops in the headphones. See “AC-Coupled click and

speaker loads during power-up and power-down. See

Figure 30 in the “Typical Performance Curves” on

page 18.

Proper elimination of a click/pop transient at the

speaker loads while powering up or down of the audio

drivers requires that the ISL54210 have its click/pop

circuitry activated by putting the part in the Mute

mode. This allows the transients generated by the

audio drivers to be discharged through the click and

pop shunt circuitry.

AC-COUPLED CLICK AND POP OPERATION

Single supply audio drivers have their signal biased at a

DC offset voltage (usually at 1/2 the DC supply voltage of

the driver). As this DC bias voltage comes up or goes

down during power-up or power-down of the driver, a

transient can be coupled into the speaker load through

the DC blocking capacitor (see the“Typical Application

Block Diagram” on page 11).

Once the driver DC bias has reached V /2 and the

DD

transient on the switch side of the DC blocking capacitor

has been discharged to ground through the click/pop

shunt circuitry, the audio switches can be turned ON and

connected through to the speaker loads without

generating any undesirable click/pop noise in the

speakers.

When a driver is OFF and then turned ON, the rapidly

changing DC bias voltage at the output of the driver will

cause an equal voltage at the input side of the switch due

to the fact that the voltage across the blocking capacitor

cannot change instantly. If the switch is in the Audio

mode or there is no low impedance path to discharge the

blocking capacitor voltage at the input of the switch,

before turning on the audio switch, a transient discharge

will occur in the speaker, generating a click/pop noise.

With a typical DC blocking capacitor of 220µF and the

click/pop shunt circuitry designed to have a resistance

of 20Ω to 70Ω, allowing a 100ms wait time to discharge

the transient before placing the switch in the Audio

mode will prevent the transient from getting through

to the speaker load. See Figures 28 and 29 in the

“Typical Performance Curves” page 17.

FN6661.2

Converted to New Intersil Template

Replaced note, page 3: “θ is measured with the component mounted on a high effective thermal

JA

conductivity test board in free air. See Tech Brief TB379 for details.” with “direct attached note”

Added “Boldface limits apply over the operating temperature range, -40°C to +85°C.” to

Electrical Specifications table.

On page 1 in “Related Literature” section added App Note AN1407.

On page 1 in “Features” section added “Low On Capacitance at 240MHz 4.2pF”

On page 2 added thermal pad (PD) to TDFN pinout and added PD column to “Pin Descriptions”

table.

Page 4 in “Abs Max Rating” section added HBM rating for COM pins of 6kV and Latchup level.

Thermal information Tjc for uTQFN changed from “61.9” to “105” and note for Tja was added

to reference no direct attach, added Tjc to show the case temp location at top center.

Page 4 in Electrical Spec Table - Removed Note Reference from Typical Column and Added to

specific specs in Audio Switches and USB Switches as follows: On Resistance, rON Matching

Between Channels and rON Flatness.

Page 6 in electrical specifications table added “On Capacitance at 240MHz parameter.

Page 15 Figure 20 Change from USB far end mask to USB near end mask.

Page 18 in “Die Characteristics” section added TDFN thermal pad potential.
