June 28, 2010 USB 2.0 High-Speed x 2 Channels/Stereo Audio Dual SP3T
(Dual 3 to 1 Multiplexer) Features The Intersil ISL54214 is a single supply dual SP3T
analog switch that operates from a single supply in
the range of 2.7V to 4.6V. It was designed to
multiplex between audio stereo signals and two
different USB 2.0 high speed differential data signals.
The audio channels allow signal swings below ground,
allowing the multiplexing of the voice and data signals
through a common headphone connector in Personal
Media Players and other portable battery powered
devices. High Speed (480Mbps) and Full Speed (12Mbps)
Signaling Capability per USB 2.0 Low Distortion Negative Signal Capability Audio
Switches Power OFF Protection COM Pins Overvoltage Tolerant to 5.5V Low Distortion Headphone Audio Signals
-0.03% THD+N at 5mW into 32О©пЂ Load The audio switch cells can pass В±1V ground
referenced audio signals with very low distortion
(<0.03% THD+N when driving 5mW into 32О© loads).
The USB switch cells have very low ON capacitance
(8pF) and high bandwidth to pass USB high speed
signals (480Mbps) with minimal edge and phase
distortion. -98dB cross-talk (100kHz) 95.5dB OFF-Isolation (100kHz) 2.7V to 4.6V Single Supply Operation (VDD) 700MHz of -3dB Bandwidth USB Switches Available in Tiny 12 Ld ВµTQFN and TQFN Packages Compliant with USB 2.0 Short Circuit …
