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 C_OFFCapacitance: 2.0pF Typical

Low On Resistance: 7.5Ω Typical

Low Power Consumption: 1μA Maximum

10μA Maximum I_CCTover an Expanded Voltage

Range (V_IN=2.6V, V_CC=4.3V)

capacitance (C_ON

)

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 (V_CC). 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
