FSA1211 — Low-Power, Twelve-Port, High-Speed Isolation Switch September 2009 FSA1211 — Low-Power, Twelve-Port, High-Speed Isolation Switch Features Low COFF Capacitance: 2.0pF Typical Low On Resistance: 7.5Ω Typical Low Power Consumption: 1μA Maximum 10μA Maximum ICCT over an Expanded Voltage Range (VIN=2.6V, VCC=4.3V) W ide -3db Bandwidth: > 720MHz Packaged in Space-Saving 28-Lead UMLP 5.5kV ESD Rating; >9kV Power/GND ESD Rating Low On Capacitance: 6pF Typical Description The FSA1211 is a low-power, twelve-port, high-speed switch. This part is configured as a single-pole, singlethrow switch (SPST) and is optimized for isolating a high-speed source, such as a cell phone camera interface. The FSA1211 features an extremely low on capacitance (CON) of 6pF. The wide bandwidth (>720MHz) exceeds the bandwidth needed to pass the third harmonic, resulting in signals with minimum edge and phase distortion. Superior channel-to-channel crosstalk minimizes interference. The FSA1211 contains special circuitry on pins A and B that allows the device to withstand an over-voltage condition. This device is designed to minimize current consumption even when the control voltage applied to the /OE pin is lower than the supply voltage (VCC). This feature is especially valuable for mobile applications, such as cell phones, allowing direct interface with the general-purpose I/Os of the baseband processor. Other applications include port isolation and switching in portable cell phones, PDAs, digital cameras, printers, and notebook computers. Applications Cell phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-Top Box IMPORTANT NOTE: For additional performance information, please contact analogswitch@fairchildsemi.com.
