FSA1211UMX

FSA1211 — Low-Power, Twelve-Port, High-Speed Isolation Switch Features Description ƒ ƒ ƒ ƒ Low COFF Capacitance: 2.0pF Typical ƒ ƒ ƒ ƒ Wide -3db Bandwidth: > 720MHz 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. 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) Packaged in Space-Saving 28-Lead UMLP 5.5kV ESD Rating; >9kV Power/GND ESD Rating 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. Low On Capacitance: 6pF Typical Applications ƒ ƒ 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.
