NOTES:
4. VLOGIC = Input voltage to perform proper function.
5. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
6. Parts are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation.
7. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal range.
8. rON matching between channels is calculated by subtracting the channel with the highest max rON value from the channel with lowest max rON
value, between NC1 and NC2 or between NO1 and NO2.

Detailed Description
NC1 and NC2 Audio/Video Switches
The ISL54207 device is a dual single pole/double throw
(SPDT) analog switch device 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 mono audio/composite video
baseband signals (CVBS). It comes in tiny TQFN and
TDFN packages for use in cameras, camcorders, video MP3
players, PDAs, cell phones, and other personal media
players.
The two NC (normally closed) audio/video switches (NC1,
NC2) are 3 switches that can pass signals that swing
below ground by as much as 1.5V. They were designed to
pass ground reference audio signals and DC restored
composite base-band signals (CVBS), including negative
synchronizing pulse with minimal insertion loss and very low
distortion and degradation.
The part consists of two 3 audio/video switches and two
5 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 high-speed USB differential
data signals with minimal edge and phase distortion.
The ISL54207 was specifically designed for digital cameras,
camcorders, MP3 players, cell phones 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 ISL54207 incorporates circuitry for the detection of the
USB VBUS voltage, which is used to switch between the
audio/video drivers and USB transceiver of the media player.
The ISL54207 contains a logic control pin (CTRL) that when
driven Low while VBUS is Low, opens all switches and puts
the part into a low power state, drawing typically 1nA of IDD
current.
The -3dB bandwidth into 75 is 338MHz (Figure 17).
Crosstalk between NC1 and NC2 @ 4MHz is -78dB
(Figure 16), 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 (0.707Vrms) with VDD > 2.7V,
these switches have an extremely low rON resistance
variation. They can pass a ground referenced audio signal
with very low distortion (<0.06% THD+N) when delivering
15.6mW into a 32headphone speaker load. See
Figures 10, 11, 12, and 13 THD+N performance curves.
Figure 8 and 9 shows the vector scope plots of a standard
NTSC color bar signal at both the input (Figure 8) and output
(Figure 9) of the ISL54207. The plots show that except for a
little attenuation due to switch rON and test fixture cabling,
there is virtually no degradation of the video waveform
through the switch.
A detailed description of the two types of switches is
provided in the following sections. The USB transmission
and audio/video playback are intended to be mutually
exclusive operations.

NO1 and NO2 USB Switches
The two NO (normally open) USB switches (NO1, NO2) are
5 bidirectional switches that are designed to pass
high-speed USB differential signals in the range of ±0V to
400mV. The switches have low capacitance and high
bandwidth to pass USB high-speed signals (480Mbps) with
minimum edge and phase distortion to meet USB 2.0 signal
quality specifications. See Figure 14 for High-speed Eye
Pattern taken with switch in the signal path.
The maximum signal range for the USB switches is from
-1.5V to VDD. The signal voltage at NO1 and NO2 should
not be allowed to exceed the VDD voltage rail or go below
ground by more than -1.5V.
The NO switches are active (turned ON) whenever the VBUS
voltage is  to VDD + 0.8V. VBUS is internally pulled low, so
when VBUS is floating, the USB switches are OFF.
FIGURE 8. VECTOR-SCOPE PLOT BEFORE SWITCH
Note: Whenever the NO 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.
ISL54207 Operation
The discussion that follows will discuss using the ISL54207 in
the typical application shown in the block diagram on page 8.
LOGIC CONTROL
The state of the ISL54207 device is determined by the
voltage at the VBUS pin (pin 2) and the CTRL pin (pin 10).
Refer to truth-table on page 2 of the data sheet.
The VBUS pin and CTRL pin are internally pulled low
through 4Mresistors to ground and can be left floating. The
CTRL control pin is only active when VBUS is logic “0”.
Logic control voltage levels:
FIGURE 9. VECTOR-SCOPE PLOT AFTER SWITCH
Figure 18 shows the differential gain (DG) and differential
phase (DP) plots at the output of the switch using an actual
NTSC composite video signal and a VM700A Video
Measurement Test Set. DG = 0.28% and DP = 0.04°.
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).
The NC switches are active (turned ON) whenever the VBUS
voltage is  to VDD + 0.2V or floating and the CTRL voltage 
to 1.4V.
Note: Whenever the NC switches are ON the USB
transceivers need to be in the high impedance state or static
high or low state.
9
VBUS = Logic “0” (Low) when VBUS VDD + 0.2V or
Floating.
VBUS = Logic “1” (High) when VBUS VDD + 0.8V
CTRL = Logic “0” (Low) when 0.5V or floating.
CTRL = Logic “1” (High) when 1.4V
Audio/Video Mode
If the VBUS pin = Logic “0” and CTRL pin = Logic “1,” the
part will be in the Audio/Video mode. In Audio/Video mode
the NC1 and NC2 3 audio/video switches are ON and the
NO1 and NO2 5 USB switches are OFF (high impedance).
In a typical application, VDD will be in the range of 2.7V to
3.6V and will be connected to the battery or LDO of the
media player. When a audio/video jack is plugged into the
common connector, nothing gets connected at the VBUS pin
(it is floating) and as long as the CTRL = Logic “1,” the
ISL54207 part remains in the audio/video mode and the
media player audio and video drivers can drive the speaker
and video display.

ISL54207
USB Mode
If the VBUS pin = Logic “1” and CTRL pin = Logic “0” or
Logic “1,” the part will go into USB mode. In USB mode, the
NO1 and NO2 5 switches are ON and the NC1 and NC2
3 audio switches are OFF (high impedance). When a USB
cable from a computer or USB hub is connected at the
common connector, the voltage at the VBUS pin will be
driven to be in the range of 4.4V to 5.25V. The ISL54207 part
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 transmitted
back and forth.
When the USB cable is disconnected, the ISL54207
automatically turns the NO1 and NO2 switches OFF.
Low Power Mode
If the VBUS pin = Logic “0” and CTRL pin = Logic “0,” the
part will be in the Low Power mode. In the Low Power mode,
the NCx switches and the NOx switches are OFF (high
impedance). In this state, the device draws typically 1nA of
current.
EXTERNAL VBUS SERIES RESISTOR
The ISL54207 contains a clamp circuit between VBUS and
VDD. Whenever the VBUS voltage is greater than the VDD
voltage by more than 2.55V, current will flow through this
clamp circuitry into the VDD power supply bus.
circuit is not active and no current will flow through the clamp
into the VDD supply.
In a USB application, the situation can exist where the VBUS
voltage from the computer could be applied at the VBUS pin
before the VDD voltage is up to its normal operating voltage
range and current will flow through the clamp into the VDD
power supply bus. This current could be quite high when
VDD is OFF or at 0V and could potentially damage other
components connected in the circuit. In the application
circuit, a 22k resistor has been put in series with the VBUS
pin to limit the current to a safe level during this situation.
It is recommended that a current limiting resistor in the range
of 10k to 50k be connected in series with the VBUS pin. It
will have minimal impact on the logic level at the VBUS pin
during normal USB operation and protect the circuit during
the time VBUS is present before VDD is up to its normal
operating voltage.
Note: No external resistor is required in applications where
VBUS will not exceed VDD by more than 2.55V.
POWER
The power supply connected at VDD (pin 1) provides power
to the ISL54207 part. Its voltage should be kept in the range
of 2.7V to 3.6V when used in a USB/Audio/Video application
to ensure you get proper switching when the VBUS voltage is
at its lower limit of 4.4V.
During normal USB operation, VDD is in the range of 2.7V to
3.6V and VBUS is in the range of 4.4V to 5.25V. The clamp
