these applications, note that if the I/O cards were plugged
directly into the backplane, all of the backplane and card
capacitances would add directly together, making rise- and
fall-time requirements difficult to meet. Placing a
LTC4300A on the edge of each card, however, isolates the
card capacitance from the backplane. For a given I/O card,
the LTC4300A drives the capacitance of everything on the
card and the backplane must drive only the capacitance of
the LTC4300A, which is less than 10pF.

figuration. Connect V
CC
and ENABLE to the output of one
of the CompactPCI power supply Hot Swap circuits. Use
a pull-up resistor to ENABLE for a card side enable/disable.
V
CC
is monitored by a filtered UVLO circuit. With the V
CC
voltage powering up after all other pins have established
connection, the UVLO circuit ensures that the backplane
and card data and clock busses are not connected until the
transients associated with live insertion have settled. Owing
to their small capacitance, the SDAIN and SCLIN pins cause
minimal disturbance on the backplane busses when they
make contact with the connector.
Figure 4 shows the LTC4300A-2 in a CompactPCI configu-
ration. The LTC4300A-2 receives its V
CC
voltage from one
of the long “early power” pins. Because this power is not
switched, add a 5
to 10
resistor between the V
CC
pins
