Description
PI3USB412 integrates two unique Pericom technology solutions
into a single IC package. It offers the user 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, Pericom’s PI3USB412 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 our
PI3USB412 device. Two channels are targeted for high speed
USB 2.0 signals (Dx), and two channels are targeted for low
THD audio signals (Ax). The two low THD audio signals are
developed in a mux configuration. Thus, the user can have two
internal sources going to a single audio output.
