FSA1211 — Low-Power, Twelve-Port, High-Speed
Isolation Switch
Features
Description
The 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
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)
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.
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
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
