Low Voltage, Dual SPDT, USB/CVBS/
Audio Switches with Negative Signal
Capability
June 27, 2006
FN6318.1
Features
• Low Distortion Negative Signal Capability
The Intersil ISL54415, ISL54416, ISL54417 dual SPDT
(Single Pole/Double Throw) switches combine low distortion
audio/video and accurate USB 2.0 Full Speed data signal
switching in the same low voltage device. When operated with
a 2.5V 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.
The ISL54415 and ISL54416 incorporate circuitry for
detection of the USB VBUS voltage, which is used to switch
between the audio/video and USB signal source in the
portable device. In addition, the ISL54415 includes circuitry for
generation of a VTERM voltage of 3.3V for use with USB
speed setting pull-up resistor.

Detailed Description
The ISL5441X family of devices are dual single pole/double
throw (SPDT) analog switches that operate from a single
power supply. They were designed to function as dual 2 to 1
multiplexers to select between USB differential data signals
and mono Audio/Composite Video Broadcast System
(CVBS). They come in tiny µTQFN package for use in digital
cameras, camcorders, video MP3 players, PDAs,
cellphones, and other personal media players.
All devices in this family consist of two 1 normally closed
(NC) Audio/Video switches and two 5 normally open (NO)
USB switches. The audio/video switches can accept signals
that swing below ground. They were designed to pass
ground reference audio or DC-restored with synch
composite video signals with minimal distortion. The USB
switches were designed to pass full-speed USB differential
data signals with minimal edge and phase distortion.
The ISL54415 and ISL54416 were specifically designed for
digital cameras, camcorders, MP3 players, cellphones and
other personal media player applications that need to
combine the audio/video jacks 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 above. The ISL54415 and ISL54416
incorporate circuitry for the detection of the USB VBUS
voltage, which is used to switch between the audio/video
drivers and USB transceiver of media player. The ISL54415
contains additional circuitry to generate the required USB
VTERM of 3.3V for use with the USB speed setting pull-up
resistor.
The ISL54417 is an audio/video and data switch who’s logic
control is typical of a standard dual SPDT device.
A detailed description of the two types of switches and of
each part type in the ISL5441X family are provided in the
following sections. The digital data transmission (USB, etc.)
9
and audio/video playback are intended to be mutally
exclusive operations.
NC1 and NC2 Audio/Video Switches
The two NC (normally closed) audio/video switches (NC1,
NC2) are 1 high bandwidth switches that can pass signals
that swing below ground by as much as 1.5V. They were
design to pass ground reference audio signals and
DC-restored Composite Video Broadcast System (CVBS)
including negative synchronizing pulse with minimal
insertion loss and very low distortion and degradation.
The -3dB bandwidth into 50 is 394MHz and into 75 is
264MHz. Crosstalk between NC1 and NC2 @ 4MHz is
-60dB which allows composite video to be routed through
one switch and mono-audio through the other switch with
little interference.
The recommended maximum signal range is from -1.5V to
1.5V. You can apply positive signals greater than 1.5V but
the RON resistance of the switch increases rapidly above
1.5V. The signal should not be allowed to exceed the VDD
rail or swing more negative than -1.5V.
Over a signal range of ±1V these switches have an
extremely low RON flatness. They can pass a ground
referenced audio signal with very low distortion (<0.007%
THD+N) when delivering 12mW into a 32headphone
speaker load. See Figures 10 and 11 THD+N performance
curves.
Figures 8 and 9 show the vector scope plots of a standard
NTSC color bar signal at both the input (Figure 8) and output
(Figure 9) of the ISL54415. The plots show that except for a
little attentuation, due to switch RON and test fixture cabling,
there is virtually no degradation of the video waveform
through the switch.

ISL54415, ISL54416, ISL54417
For the ISL54415 and ISL54416 parts the NC audio/video
switches are active (turned ON) whenever the VBUS voltage
is VDD + 0.2V. The VBUS pin is internally pulled low
through a pull-down resistor allowing the VBUS pin to float.
When the VBUS pin is floating the NC audio/video switches
are ON.
Note: Whenever the audio/video switches are ON the USB
transceivers need to be in the high impedance state or static
high or low state to keep from interfering with the audio/video
transmission.
FIGURE 8. VECTOR-SCOPE PLOT BEFORE SWITCH
For the ISL54417 part the NC1 audio/video switch is active
(turned ON) whenever logic pin IN1 (pin 10) is LOW. The
NC2 audio/video switch is active (turned ON) whenever the
logic pin IN2 (pin 2) is LOW. Unlike the ISL54415 and
ISL54416 parts were the two SPDT switches work in
tandem, the ISL54417 gives you independent control over
each SPDT switch.
NO1 and NO2 USB Switches
The two NO (normally open) USB switches (NO1, NO2) are
5 bidirectional switches that were designed to pass low
speed and full-speed USB differential signals typically in the
range of 0V to 3.6V. The switches have low capacitance
(0.47pF) and high bandwidth (239MHz) to pass USB fullspeed signals (12Mbps) with minimum edge and phase
distortion to meet USB 2.0 signal quality specifications. See
Figure 12 for full-speed USB eye diagram.
For the ISL54415 and ISL54416 parts the maximum signal
range for the USB switches is from -1.5V to VBUS. The
signal voltage should not be allow to exceed the VBUS
voltage rail or go below ground by more than -1.5V.
FIGURE 9. VECTOR-SCOPE PLOT AFTER SWITCH
Figure 15 shows the measured gain and phase of a
3.58MHz, 300MVP-P signal at the output of the switch
relative to the signal at the input of the switch as you vary the
DC offset of the signal from 0V to 1V using a network
analyzer. The data from the sweep was used to calculated
the differential gain (DG) and differential phase (DP). Over
luminance range of 0V to 1V: DG = 0.03% and DP = 0.05°.
Over luminanace range of 0V to 0.7V: DG = 0.03% and
DP = 0.03°. DG and DP plot using an actual NTSC video
signal is shown in Figure 16. DG = 0.05% and DP = 0.02°.
These NC switches are uni-directional switches. The
audio/video sources should be connected at the NC side of
the switch (pins 7 and 8) and the speaker load and video
receiver should be connected at the COM side of the switch
(pins 3 and 4).
10
For the ISL54417 part the maximum signal range is from
-1.5V to VDD. The signal voltage should not be allowed to
exceed the VDD voltage rail or go below ground by more
than -1.5V.
When using the ISL54415 and ISL54416 parts the USB
switches are active (turned ON) whenever the VBUS voltage
is VDD + 0.8V. VBUS is internally pulled low, so when VBUS
is floating the USB switches are OFF.
Note: Whenever the USB switches are ON the audio and
video drivers need to be at AC or DC ground or floating to
keep from interfering with the data transmission.
When using the ISL54417 part the NO1 USB switch is active
(turned ON) whenever logic pin IN1 (pin 10) is HIGH. The
NO2 USB switch is active (turned ON) whenever the logic
pin IN2 (pin 2) is HIGH. Unlike the ISL54415 and ISL54416
parts were the two SPDT switches work in tandem, the
ISL54417 gives you independent control over each SPDT
switch.

ISL54415, ISL54416, ISL54417
ISL54415 and ISL54416 Operation
VTERM OPERATION (ISL54415 ONLY)
The ISL54415 and ISL54416 function the same except the
ISL54416 does not have the VTERM feature. The discussion
that follows pertains to both devices and will discuss using the
parts in the typical application shown in the block diagram on
page 10.
When a USB cable from a computer is connected to a USB
device a VTERM voltage must be applied to a speed
indicating pull-up resistor to properly terminate the bus and
identify whether the USB device is a full-speed or low-speed
device to facilitate proper digital transmission. When the
cable is removed from the device this VTERM voltage must
be disconnected from the speed indicating pullup resistor.
The ISL54415 device can perform this operation.
LOGIC CONTROL
The state of the ISL54415 and ISL54416 devices are
determined by the voltage at the VBUS pin (pin 2). The VBUS
pin is internally pulled low and can be left floating.
If VBUS (pin 2) is floating or the VBUS voltage  VDD + 0.2V
the part will be in the audio/video mode. In Audio/Video
mode the NC1 and NC2 1 audio/video switches are ON
and the NO1 and NO2 5 USB switches are OFF (high
impedance). In this state power to the part is provided by the
DC voltage connected at the VDD pin (pin 1). In a typical
application VDD will be in the range of 2.5V to 3.6V and will
be connected to the battery or LDO of the media player.
When a headphone/video receiver is plugged into the
common connector, nothing gets connected at the VBUS pin
(its floating) and the ISL54415 and ISL54416 parts remains
in the audio/video mode and the media player audio and
video drivers can drive the headphones and video display.
If VBUS (pin 2) voltage is greater than VDD by 0.8V the part
will go into USB mode. In USB mode the NO1 and NO2 5
USB switches are ON and the NC1 and NC2 1 audio/video
switches are OFF (high impedance). In this state the part will
be powered by the voltage connected at the VBUS pin (pin
2). When a USB cable from a computer or USB hub is
connected at the common connector the VBUS voltage is
driven to between 4.4V and 5.25V. The ISL54415 and
ISL54416 parts will go into the USB mode. In USB mode the
computer or USB hub transceiver and the media player USB
transceiver are connected and digital data will be able to be
transmit back and forth.
When the USB cable is disconnected the switch
automatically turns the NO1 and NO2 switches OFF and
turns the NC1 and NC2 audio/video switches ON.
POWER
In audio/video mode the power supply connected at VDD
(pin 1) provides power to the ISL54415 and ISL54416 parts.
Its voltage should be kept in the range of 2.5V to 3.6V when
used in a USB application to ensure you get proper
switching when the VBUS voltage is at its lower limit of 4.4V.
When VDD  2.5V and VBUS  VDD + 0.8V, the VTERM pin
(pin 10) outputs an open circuit voltage equal to the voltage
at the VBUS pin. Otherwise the VTERM pin will be in a HI-Z
state.
The ISL54415 VTERM circuitry has an internal series resistor
approximately equal to 5.3k. For a full-speed USB
application it is recommended you use a 3k ±5% speed
indicating pull-up resistor. When the USB bus is in the idle
state, a 3k ±5% resistor will put the D+ line voltage in the
range of 2.7V to 3.6V as required by the USB specification.
For low-speed USB application it is recommend you use a
2k ±5% pull-up resistor at the D- line in order to meet the
USB connect and disconnect timing requirements.
ISL54417 Operation
The ISL54417 is an audio/video and data switch. Its logic
control is typical of a standard dual SPDT switch.
The digital control for the ISL54417 are the IN pins (pin 2
and pin 10). These pins are 1.8V logic compatible when
operated with a 3.0V supply. The device has been designed
to have low IDD current even when the logic voltage is not at
the rail. With VDD = 5.5V and VIN = 2.85V the ISL54417
draws only 8µA current.
When logic pin IN1 (pin 10) is LOW the NC1 audio/video
switch is ON and the NO1 USB data switch is OFF. When
logic pin IN1 (pin 10) is HIGH the NC1 audio/video switch is
OFF and the NO1 USB data switch is ON.
When logic pin IN2 (pin 2) is LOW the NC2 audio/video
switch is ON and the NO2 USB data switch is OFF. When
logic pin IN2 (pin 2) is HIGH the NC2 audio/video switch is
OFF and the NO2 USB data switch is ON.
Power for the ISL54417 device is always provided by the DC
voltage source connected at the VDD pin (pin 1). The VDD
power supply voltage range is from 1.8V to 5.5V.
In USB mode power for the ISL54415 and ISL54416 parts is
provided from the VBUS line from the host USB controller of
the computer or USB hub. Its voltage will be between 4.4V
and 5.25V.
