Description

PI3USB411 integrates two unique Pericom technology solutions

into a single IC package. PI3USB411 offers the customer a

solution that switches both high speed differential signals, with

high bandwidth performance, as well as low THD audio signals.

For handheld applications where both a USB data transfer port

and a port for an external headset is required, the PI3USB411

solution can offer the ability to combine the two ports into one.

With a single port, design engineers are faced with an issue of

switching two completely different types of signals. One signal

is a high speed differential signal, where bandwidth is the largest

concern, and the second signal is an audio signal, where low THD

is the largest concern. Pericom’s solution offers multiple channels

within the PI3USB411 device. Two channels are targeted for high

speed USB2.0 signals (Dx), and two channels are targeted for low

THD audio signals (Ax). Due to its passive nature, all paths will

allow bi-directional traffic.
