January 9, 2015 Automotive Grade USB 2.0 High/Full Speed Multiplexer Features 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. High speed (480Mbps) and full speed (12Mbps) signaling
capability per USB 2.0 1.8V logic compatible (2.7V to +3.6V supply) Enable pin to open all switches, simplifies multiple USB
client management 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. -3dB frequency
-HSx switches 880MHz
-FSx switches 550MHz Crosstalk at 1MHz -70dB 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 …
