BCT642
Low-Power, Three-Port , High-Speed MIPI Switch
GENERAL DESCRIPTION
The BCT642 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
BCT642 is optimized for switching between two
MIPI devices, such as cameras or LCD displays
and on-board Multimedia Application Processors
(MAP).
The BCT642 is compatible with the requirements
of Mobile Industry Processor Interface (MIPI). The
low-capacitance design allows the BCT642 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. BCT642 is a direct replacement for
FSA642.

This integrated circuit can be damaged by ESD if you don’t
pay attention to ESD protection. Broadchip recommends
that all integrated circuits be handled with appropriate
precautions. Failure to observe proper handling and
installation procedures can cause damage. ESD damage
can range from subtle performance degradation to
complete device failure. Precision integrated circuits may
be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
Broadchip reserves the right to make any change in circuit
design, specification or other related things if necessary
without notice at any time. Please contact Broadchip sales
office to get the latest datasheet.
