FSA2457UMX

The FSA2457UMX 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 FSA2457UMX is compatible with the requirements of 1-bit SIM/SD/MMC cards and is ideal for interfacing to GPS baseband processors. The FSA2457UMX features a low on capacitance (CON) of 12pF to ensure high-speed data transfer. The FSA2457UMX 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
