June 17, 2010 USB 2.0 High/Full Speed Multiplexer Features The Intersil ISL54200 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 -3dB Frequency
-HSx Switches 880MHz
-FSx Switches 550MHz The 7пЃ—пЂ 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 4.5пЃ— 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. Crosstalk @ 1MHz -70dB Off Isolation @ 100kHz -98dB Single Supply Operation (VDD) . 2.7V to 5.5V Available in Ultra-thin ВµTQFN and TDFN Packages The part can be used in Personal Media Players and
other portable battery powered devices that need to
switch between a high-speed transceiver and a fullspeed transceiver while connected to a single USB
host (computer). Pb-Free (RoHS Compliant) Applications*(see page 16) MP3 and other Personal Media Players The digital logic inputs are 1.8V logic compatible when
operated with a 2.7V to 3.6V supply. The part has an …
