Manufacturer Part Number
ISL54217_09
Description
USB 2.0 High-Speed x 2Channels/Stereo Audio Dual SP3T (Dual 3-to-1 Multiplexer)
Manufacturer
INTERSIL [Intersil Corporation]
Datasheet
USB 2.0 High-Speed x 2Channels/Stereo
Audio Dual SP3T (Dual 3-to-1 Multiplexer)
The Intersil ISL54217 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 voice and data signals
through a common headphone connector in Personal Media
Players and other portable battery powered devices.
The audio switch cells can pass ±1V ground referenced audio
signals with very low distortion (<0.03% THD+N when driving
5mW into 32Ω 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.
The ISL54217 is available in a tiny 12 Ld 2.2mmx1.4mm ultra
thin QFN and a 12 Ld 3mmx3mm TQFN package. It operates
over a temperature range of -40°C to +85°C.
