Automotive Grade USB 2.0 High/Full Speed Multiplexer
ISL76120
The Intersil ISL76120 dual 2:1 multiplexer IC is a single supply
part that can operate from a single 2.7V to 5.5V supply. It
contains two SPDT (Single Pole/Double Throw) switches
configured as a DPDT. The part was designed for switching
between USB high-speed and USB full-speed sources in portable
battery powered products.
The normally-closed (NC) FSx switches can swing rail-to-rail and
were specifically designed to pass USB full speed data signals
(12Mbps) that range from 0V to 3.6V. The normally-open (NO)
HSx switches have high bandwidth and low capacitance and
were specifically designed to pass USB high speed data signals
(480Mbps) with minimal distortion.
The part can be used in a variety of automotive entertainment
and infotainment applications where consumer USB devices
such as Portable Media Players (PMPs) are to be connected to
embedded systems. The product allows switching between a
high-speed transceiver and a full-speed transceiver while
connected to a single USB host. Additionally, the part can be
used for charge control of PMPs.
The digital logic inputs are 1.8V logic compatible when operated
with a 2.7V to 3.6V supply. The part has an enable pin to open
all switches. It can be used to facilitate proper bus disconnect
and connection when switching between the USB sources.
The ISL76120 is available in a 10 Ld 3mmx3mm TDFN
package. It operates across a temperature range of -40°C to
+105°C.
