January 24, 2007
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 full-
speed eye diagram Figure 11.
The maximum signal range for the HSx switches is from
-1.5V to V
DD
. The signal voltage should not be allow to
exceed the V
DD
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
The discussion that follows will discuss using the ISL54200 in
the typical application shown in the block diagram on page 9.
POWER
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.
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 4M
Ω
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 V
EN
≤
0.5V or Floating.
EN = Logic “1” (High) when V
EN
≥
1.4V
IN = Logic “0” (Low) when V
IN
≤
0.5V.
IN = Logic “1” (High) when V
IN
≥
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 V
DD
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
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.
All Switches OFF Mode
If the IN pin = Logic “0” or Logic “1” and EN pin = Logic “0” all
of the switches will turn OFF (high impedance).
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.
