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 triple-
pole, 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 low-
capacitance design allows the FSA642 to switch signals
that exceed 500MHz in frequency. Superior channel-to-
channel crosstalk immunity minimizes interference and
allows the transmission of high-speed differential
signals and single-ended signals, as described by the
MIPI specification.
