Business Wire
Diodes Incorporated (Nasdaq: DIOD) today announced the PI3A6386
USB Type-C™ multimedia port switch, designed to enable
manufacturers to continue supporting legacy data and analog
peripherals through USB Type-C ports. As a result of the adoption
of USB Type-C ports in mobile phones and tablets, manufacturers are
removing other ports such as USB 2.0 and 3.5mm audio sockets. The
PI3A6386 port switch enables legacy data and audio signals to be
passed through the USB Type-C port, allowing consumers to continue
using existing peripherals.
The performance of the PI3A6386 port switch ensures a high level
of audio quality, without signal distortion or noise. It includes
autonomous microphone and ground line switching, while its CMOS
design delivers an ON resistance of just 1Ω for the audio switching
transistor. Low crosstalk between data and audio channels was also
a design priority for the PI3A6386, and it succeeds here with a
crosstalk rejection of -85dB at 30kHz.
Other design features include a programmable soft-start and
soft-stop time, which eliminates the pop and click that audio
signals can experience when they are DC-coupled. This delivers an
audio experience free from distortion. The PI3A6386 operates from a
supply of between 1.7V and 5.5V, making it suitable for portable
devices. It can also process signals of ±3V, which further improves
the dynamic range and audio quality.
The PI3A6386 supports USB 2.0 High Speed and Full Speed signals
and USB Type-C Audio Accessory Mode. The THD of -110dB is
maintained from 20Hz to 20kHz with a signal of 2.0V RMS into a 32Ω
load. Separate ground switches are also used for the audio and data
signals, to further minimize crosstalk.
The PI3A6386 is available in the TQFN-24 package. Further
information is available at www.diodes.com.
