FSA2457 — Dual DPDT, 5Ω Analog Data Switch

Features

Description

The FSA2457 is a bi-directional, low-power, dual

double-pole double-throw (4PDT) analog switch

targeted at dual 1-bit SIM/SD/MMC card and/or GPS

signal multiplexing. It is optimized for switching the

WLAN-SIM data and control signals at 52Mbps.

Low On Capacitance for Data Path: 12pF Typical

Low On Resistance for Data Path: 5Ω Typical

Low Power Quiescent Consumption: 1μA Maximum

Wide -3db Bandwidth: > 160MHz

Packaged in:

The FSA2457 is compatible with the requirements of 1-

bit SIM/SD/MMC cards and is ideal for interfacing to

GPS baseband processors. The FSA2457 features a

low on capacitance (C_ON) of 12pF to ensure high-speed

data transfer.

-Pb-free 16-Lead UMLP (1.8 x 2.6mm)

4kV JEDEC: JESD22-A114 HBM

2kV JEDEC: JESD22-C101 CDM

The FSA2457 contains special circuitry that minimizes

current consumption even when the control voltage

applied to the SEL pin is lower than the supply voltage

(V_CC). This feature is especially valuable in ultra-

portable applications, such as cell phones; allowing

direct interface with the general-purpose I/Os of the

baseband processor. Other applications include

switching and connector sharing in portable cell

phones, PDAs, digital cameras, printers, and portable

GPS systems.

Applications

Cell Phone, PDA, Digital Camera, Portable GPS

LCD Monitor, TV, Set-Top Box
