FSA3230 — High-Speed USB2.0 / Mobile HighDefinition Link (MHL™) with Negative Swing Audio Features Description  Low On Capacitance: 6 pF / 6 pF MHL / USB (Typical)        Low Power Consumption: 30 μA Maximum 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-TheGo (OTG) communication for the USB Path OR CBUS for the MHL Path. Supports MHL Rev. 2.0 MHL Data Rate: 4.0 Gbps Audio Swing: -1.5 V to +1.5 V (Typical) VBUS Powers Device with No VCC Packaged in 16-Lead UMLP (1.8 x 2.6 mm) Over-Voltage Tolerance (OVT) on all USB Ports, Up to 5.25 V without External Components Applications  Cell Phones and Digital Cameras The FSA3230 contains special circuitry on the switch I/O pins, for applications where the VCC supply is powered off (VCC=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 (VCC). 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.

Control inputs should never be left floating or unconnected. To guarantee default switch closure to the USB position, the SEL[0:1] pins should be tied to GND with a weak pull-down resistor (3 MΩ) to minimize static current draw. © 2012 Fairchild Semiconductor Corporation FSA3230 • Rev. 1.0.2 FSA3230 — High-Speed USB2.0 Switch/Mobile High-Definition Link (MHL™) Switch with Negative Swing Audio Analog Symbol www.fairchildsemi.com 2 SEL0 Vcc 3 2 1 4 D- 13 ID_USB ID_USB 8 11 12 MHL- GND CBUS MHL+ 9 MHL+ 10 10 MHL- CBUS 11 GND 9 12 Figure 2.
