Description
The FSA642 is a bi-directional, low-power, high-speed analog switch. The pin out is designed to ease differential signal layout and is configured as a triplepole, double-throw switch (TPDT). The FSA642 is optimized for switching between two MIPI devices, such as cameras or LCD displays and on-board Multimedia Application Processors (MAP). The FSA642 is compatible with the requirements of Mobile Industry Processor Interface (MIPI). The lowcapacitance design allows the FSA642 to switch signals that exceed 500 MHz in frequency. Superior channel-tochannel crosstalk immunity minimizes interference and allows the transmission of high-speed differential signals and single-ended signals, as described by the MIPI specification.
Conditions
IIN=-18 mA VSW=0 to 4.3 V VIN=0 to VCC VIN=0 to VCC A,B=0+0.3 V to VCC-0.3 VCNTRL=0 or VCC, IOUT=0 VCNTRL=1.8 V
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only.
