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.
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 (CON) of 12pF to ensure high-speed
data transfer.
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
(VCC). 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.
