General Description
|
TThe FSA1211 is a low-power, twelve-port, high-speed switch. This part is configured as a single-pole, single-throw 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.
