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. Parameters with limits 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. r(ON) matching between channels is calculated by subtracting the channel with the highest max r(ON) value from the channel with lowest max
r(ON) value, between HSD2 and HSD1 or between FSD2 and FSD1.

PORTABLE MEDIA DEVICE
Detailed Description
The ISL54200 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 5.5V. It was designed to
function as dual 2-to-1 multiplexer to select between a USB
high-speed transceiver and a USB full-speed transceiver in
portable battery powered products. It is offered in a TDFN
package and a small µTQFN package for use in MP3
players, cameras, PDAs, cellphones, and other personal
media players. The device has an enable pin to open all
switches.
The part consist of two 7Ω full speed (FSx) switches and two
4.5Ω high speed (HSx) switches. The FSx switches can
swing from 0V to VDD. They were designed to pass USB fullspeed (12Mbps) differential data signals with minimal
distortion. The HSx switches have high bandwidth and low
capacitance to pass USB high-speed (480Mbps) differential
data signals with minimal edge and phase distortion.
The ISL54200 was designed for MP3 players, cameras,
cellphones, and other personal media player applications
that have both high-speed and full-speed transceivers and
need to multiplex between these USB sources to a single
USB host (computer). A typical application block diagram of
this functionality is shown above.
A detailed description of the two types of switches are
provided in the sections below.
FSx Switches (FSD1, FSD2)
The two FSx switches (FSD1, FSD2) are bidirectional
switches that can pass rail-to-rail signals. When powered
with a 3.3V supply, these switches have a nominal r(ON)
resistance of 7Ω over the signal range of 0V to 3.3V. They
8
were specifically designed to pass USB full-speed (12Mbps)
differential signals and meet the USB 2.0 full-speed signal
quality specifications. See eye diagram Figure 8.
The FSx switches can also pass USB high speed signals
(480Mbps) but do not quite meet the USB 2.0 high speed
signal quality eye diagram compliance requirement.
The maximum signal range for the FSx switches 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 operated with a 2.7V to 3.6V supply, the FSx switches
are active (turned ON) whenever the IN logic control voltage
is ≤0.5V and the EN logic voltage ≥1.4V.
HSx Switches (HSD1, HSD2)
The two HSx switches (HSD2, HSD1) are bidirectional
switches that can pass rail-to-rail signals. When powered
with a 3.3V supply these switches have a nominal r(ON) of
4.5Ω over the signal range of 0V to 400mV with a r(ON)
flatness of 0.4Ω. The r(ON) matching between the HSD1 and
HSD2 switches over this signal range is only 0.01Ω ensuring
minimal impact by the switches to USB high speed signal
transitions. As the signal level increases the r(ON) switch,
resistance increases. At signal level of 3.3V the switch
resistance is nominally 20Ω.
The HSx switches were specifically designed to pass USB
2.0 high-speed (480Mbps) differential signals typically in the
range of 0V to 400mV. They have low capacitance and high
bandwidth to pass the USB high-speed signals with
minimum edge and phase distortion to meet USB 2.0 high
speed signal quality specifications. See high-speed eye
diagrams Figures 9 and 10.

ISL54200
The HSx switches can also pass USB full-speed signals
(12Mbps) with minimal distortion and meet all the USB
requirements for USB 2.0 full-speed signaling. See fullspeed eye diagram Figure 11.
The maximum signal range for the HSx switches is from
-1.5V to VDD. The signal voltage should not be allow to
exceed the VDD voltage rail or go below ground by more
than -1.5V.
The HSx switches are active (turned ON) whenever the IN
voltage is ≥1.4V and the EN logic voltage ≥1.4V when
operated with a 2.7V to 3.6V supply.
ISL54200 Operation
computer. The device will be able to transmit and receive
data from the computer at a data rate of 12Mbps.
High-speed Mode
If the IN pin = Logic “1” and EN pin = Logic “1” the part will go
into high-speed mode. In high-speed mode the HSD1 and
HSD2 switches are ON and the FSD1 and FSD2 switches
are OFF (high impedance). When a USB cable from a
computer or USB hub is connected at the common USB
connector and the part is in the high-speed mode a link will
be established between the high-speed driver section of the
media player and the computer. The device will be able to
transmit and receive data from the computer at a data rate of
480Mbps.
The discussion that follows will discuss using the ISL54200 in
the typical application shown in the block diagram on page 9.
All Switches OFF Mode
POWER
If the IN pin = Logic “0” or Logic “1” and EN pin = Logic “0” all
of the switches will turn OFF (high impedance).
The power supply connected at the VDD (pin 1) provides the
DC bias voltage required by the ISL54200 part for proper
operation. The ISL54200 can be operated with a VDD
voltage in the range of 2.7V to 5.5V. When used in a USB
application the VDD voltage should be kept in the range of
3.0V to 5.5V to ensure you get the proper signal levels for
good signal quality.
The all OFF state can be used to switch between the two
USB sections of the media player. When disconnecting from
one USB device to the other USB device you can
momentarily put the ISL54400 switch in the “all off” state in
order to get the computer to disconnect from the one device
so it can properly connect to the other USB device when that
channel is turned ON.
A 0.01µF or 0.1µF decoupling capacitor should be
connected from the VDD pin to ground to filter out any power
supply noise from entering the part. The capacitor should be
located as close to the VDD pin as possible.
LOGIC CONTROL
The state of the ISL54200 device is determined by the
voltage at the IN pin (pin 2) and the EN pin (pin 10). IN is
only active when the EN pin is logic “1” (High). Refer to“Truth
Table” on page 2.
The EN pin is internally pulled low through a 4MΩ resistor to
ground. For logic “0” (Low) it can be driven low or allowed to
Float. The IN pin must be driven low or high and cannot be
left floating.
Logic control voltage levels:
EN = Logic “0” (Low) when VEN ≤0.5V or Floating.
EN = Logic “1” (High) when VEN ≥1.4V
IN = Logic “0” (Low) when VIN ≤0.5V.
IN = Logic “1” (High) when VIN ≥1.4V
Full-speed Mode
If the IN pin = Logic “0” and EN pin = Logic “1” the part will be
in the full-speed mode. In this mode the FSD1 and FSD2
switches are ON and the HSD1 and HSD2 switches are OFF
(high impedance). In a typical application VDD will be in the
range of 2.8V to 3.6V and will be connected to the battery or
LDO of the portable media device. When a computer or USB
hub is plugged into the common USB connector and the part
is in the full-speed mode a link will be established between
the full-speed driver section of the media player and the
