I
2C Bus Isolation
The FXMAR2104 supports I
2C-Bus isolation for the
following conditions:
Bus isolation if bus clear
Bus isolation if either V
CC goes to ground
Bus Clear
Because the I
2C specification defines the minimum SCL
frequency of DC, the SCL signal can be held LOW
forever; however, this condition shuts down the I
2C bus.
The I
2C specification refers to this condition as Bus
Clear. In Figure 6, if slave #2 holds down SCL forever,
the master and slave #1 are not able to communicate
because the FXMAR2104 passes the SCL stuck-LOW
condition from slave #2 to slave #1 as well as the
master. However, if the OE pin is pulled LOW
(disabled), both ports (A and B) are 3-stated. This
results in the FXMAR2104 isolating slave #2 from the
master and slave #1, allowing full communication
between the master and slave #1.
Either VCC to GND
If slave #2 is a camera that is suddenly removed from
the I
2C bus, resulting in V
CCB transitioning from a valid
VCC
(1.65V
–
5.5V)
to
0V;
the
FXMAR2104
automatically forces all I/Os on both its A and B ports
into 3-state. Once VCCB has reached 0V, full I
2C
communication between the master and slave #1
remains undisturbed.
