Detailed Description
The ISL54222A device is a dual single pole/double throw
(SPDT) analog switch configured as a DPDT that operates
from a single DC power supply in the range of 1.8V to 3.3V.
It was designed to function as a dual 2-to-1 multiplexer to
select between two USB high-speed differential data signals
in portable battery powered products. It is offered in MSOP,
TDFN and small µTQFN packages for use in MP3 players,
cameras, PDAs, cellphones, and other personal media
players. The device has an enable pin to open all switches
and put the part in a low power down state.
The part consists of four 5.7
Ω high speed (HSx) switches.
These switches have high bandwidth and low capacitance to
pass USB high-speed (480Mbps) differential data signals
with minimal edge and phase distortion. They can also swing
from 0V to 3.3V to pass USB full speed (12Mbps) differential
data signals with minimal distortion.
The ISL54222A was designed for MP3 players, cameras,
cellphones, and other personal media player applications
that have multiple high-speed or full-speed transceivers
sections and need to multiplex between these USB sources
to a single USB host (computer). A typical application block
diagram of this functionality is previously shown.
A detailed description of the HS switches is provided in the
following section.
High-Speed (HSx) Switches
The HSx switches (HSD1-, HSD1+, HSD2-, HSD2+) are
bi-directional switches that can pass 0V to 3.3V signals.
When powered with a 1.8V supply, these switches have a
nominal rON of 5.7Ω over the signal range of 0V to 400mV
with a rON flatness of 0.60Ω. The rON matching between the
HSD1 and HSD2 switches over this signal range is only
0.072
Ω, ensuring minimal impact by the switches to USB
high speed signal transitions. As the signal level increases,
the rON switch resistance increases. With supply of 1.8V, the
switch resistance with the signal level at the rail is nominally
12
Ω. See Figures 7, 8, 9, 10, 11 and 12 in the “Typical
Performance Curves” beginning on page 10.
The HSx switches were specifically designed to pass USB
2.0 high-speed (480Mbps) differential signals in the range of
0V to 400mV. They have low capacitance (6.7pF) 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 Figure 13 in the
“Typical Performance Curves” on page 11 for USB
High-speed Eye Pattern taken with switches in the
differential signal paths.
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 Figures 14
and 15 in the “Typical Performance Curves” on page 12 for
USB Full-speed Eye Patterns taken with switches in the
differential signal paths.
The maximum normal operating signal range for the HSx
switches is from 0V to 3.3V. The signal voltage should not be
allowed to exceed 3.3V or go below ground by more than
-0.3V for normal operation.
However, in the event that the USB 5.25V VBUS voltage gets
shorted to one or both of the D-/D+ pins, the ISL54222A has
special fault protection circuitry to prevent damage to the
ISL54222A part. The fault circuitry allows the signal pins (D-,
D+, HSD1-, HSD1+, HSD2-, HSD2+) to be driven up to 5.5V
while the VDD supply voltage is in the range of 0V to 3.3V. In
this condition, the part draws < 300µA of IDD current and
causes no stress to the IC. In addition, when VDD is at 0V
(ground) all switches are OFF and the fault voltage is isolated
from the other side of the switch. When VDD is in the range of
