Detailed Description
The ISL54208 device is a dual single pole/double throw
(SPDT) analog switch device that can operate from a single
dc power supply in the range of 1.8V to 5.5V. It was
designed to function as a dual 2 to 1 multiplexer to select
between USB differential data signals and mono
audio/composite video baseband signals (CVBS). It comes
in tiny μTQFN and TDFN packages for use in cameras,
camcorders, video MP3 players, PDAs, cell phones, and
other personal media players.
The part consists of two 3
Ω audio/video switches and two
5
Ω USB switches. The audio/video switches can accept
signals that swing below ground. They were designed to
pass ground reference audio or dc restored with synch
composite video signals with minimal distortion. The USB
switches were designed to pass high-speed USB differential
data signals with minimal edge and phase distortion.
The ISL54208 was specifically designed for digital cameras,
camcorders, MP3 players, cell phones and other personal
media player applications that need to combine the
audio/video jacks and the USB data connector into a single
shared connector, thereby saving space and component
cost. Typical application block diagrams of this functionality
is shown above.
The ISL54208 logic control pins are 1.8V logic compatible
and can be driven by a standard μcontroller. It has a single
logic control pin (IN) that selects between the audio/video
switches and the USB switches. The ISL54208 also contains
a logic control pin (CTRL) that when driven Low while IN is
Low, opens all switches and puts the part into a low power
state, drawing typically 1nA of IDD current.
A detailed description of the two types of switches is
provided in the sections below. The USB transmission and
