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.
