FSA1211 Low-Power, Twelve-Port, High-Speed Isolation Switch October 2009 FSA1211 Low-Power, Twelve-Port, High-Speed Isolation Switch Features Low COFF Capacitance 2.0pF Typical Low On Resistance Typical Low Power Consumption 1uA Maximum 10uA Maximum ICCT over an Expanded Voltage Range VIN=2.6V, VCC=4.3V Wide -3db Bandwidth > 720MHz Packaged in Space-Saving 28-Lead UMLP 5.5kV ESD Rating >9kV Power/GND ESD Rating Low On Capacitance 6pF Typical Applications Cell phone, PDA, Digital Camera, and Notebook LCD Monitor, TV, and Set-Top Box IMPORTANT NOTE: For additional performance information, please contact 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.
