Detailed Description
The ISL5441X family of devices are dual single pole/double
throw (SPDT) analog switches that operate from a single
power supply. They were designed to function as dual 2 to 1
multiplexers to select between USB differential data signals
and mono Audio/Composite Video Broadcast System
(CVBS). They come in tiny µTQFN package for use in digital
cameras, camcorders, video MP3 players, PDAs,
NC1 and NC2 Audio/Video Switches
The two NC (normally closed) audio/video switches (NC1,
NC2) are 1 high bandwidth switches that can pass signals
that swing below ground by as much as 1.5V. They were
design to pass ground reference audio signals and

insertion loss and very low distortion and degradation.
cellphones, and other personal media players.
All devices in this family consist of two 1 normally closed
(NC) Audio/Video switches and two 5 normally open (NO)
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 full-speed USB differential
data signals with minimal edge and phase distortion.
The -3dB bandwidth into 50 is 394MHz and into 75 is
264MHz. Crosstalk between NC1 and NC2 @ 4MHz is
-60dB which allows composite video to be routed through
one switch and mono-audio through the other switch with
little interference.
The recommended maximum signal range is from -1.5V to
1.5V. You can apply positive signals greater than 1.5V but
The ISL54415 and ISL54416 were specifically designed for
digital cameras, camcorders, MP3 players, cellphones 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. A typical application block diagram of this
functionality is shown above. The ISL54415 and ISL54416

Note: Whenever the audio/video switches are ON the USB

(turned ON) whenever logic pin IN1 (pin 10) is LOW. The
NC2 audio/video switch is active (turned ON) whenever the
logic pin IN2 (pin 2) is LOW. Unlike the ISL54415 and
ISL54416 parts were the two SPDT switches work in

each SPDT switch.
FIGURE 8. VECTOR-SCOPE PLOT BEFORE SWITCH
NO1 and NO2 USB Switches
The two NO (normally open) USB switches (NO1, NO2) are
5 bidirectional switches that were designed to pass low
speed and full-speed USB differential signals typically in the
range of 0V to 3.6V. The switches have low capacitance
(0.47pF) and high bandwidth (239MHz) to pass USB full-
speed signals (12Mbps) with minimum edge and phase
distortion to meet USB 2.0 signal quality specifications. See
Figure 12 for full-speed USB eye diagram.

signal is shown in Figure 16. DG = 0.05% and DP = 0.02°.
Note: Whenever the USB switches are ON the audio and
video drivers need to be at AC or DC ground or floating to
keep from interfering with the data transmission.
When using the ISL54417 part the NO1 USB switch is active
(turned ON) whenever logic pin IN1 (pin 10) is HIGH. The
NO2 USB switch is active (turned ON) whenever the logic
pin IN2 (pin 2) is HIGH. Unlike the ISL54415 and ISL54416
parts were the two SPDT switches work in tandem, the
ISL54417 gives you independent control over each SPDT
switch.
These NC switches are uni-directional switches. The
audio/video sources should be connected at the NC side of
the switch (pins 7 and 8) and the speaker load and video
receiver should be connected at the COM side of the switch
(pins 3 and 4).
