Description
The FSA3230 is a bi-directional, low-power, high-speed,
3:1, USB2.0, MHL™ and audio switch. Configured as a
double-pole, triple-throw (DP3T) switch, it is optimized
for switching between high- or full-speed USB, Mobile
High-Definition Link sources (per MHL Rev. 2.0
specification) and negative swing capable audio. A
Single-Pole, Double-Throw (SPDT) switch is provided
for ID. This ID switch provides path to support On-The-
Go (OTG) communication for the USB Path OR CBUS
for the MHL Path.
The FSA3230 contains special circuitry on the switch
I/O pins, for applications where the V_CC supply is
powered off (V_CC=0), that allows the device to withstand
an over-voltage condition. This switch is designed to
minimize current consumption even when the control
voltage applied to the control pins is lower than the
supply voltage (V_CC). This is especially valuable in
mobile applications, such as cell phones; allowing direct
interface with the general-purpose I/Os of the baseband
processor. Other applications include switching and
connector sharing in portable cell phones, digital
cameras, and notebook computers.
