DESCRIPTION
The PCA9510 and PCA9511 are hot swappable I
2
C and SMBus
buffers that allows I/O card insertion into a live backplane without
corrupting the data and clock buses. Control circuitry prevents the
backplane from being connected to the card until a stop command
or bus idle occurs on the backplane without bus contention on the
card. When the connection is made, the PCA9510 and PCA9511
provides bi-directional buffering, keeping the backplane and card
capacitances isolated.
The PCA9511 rise time accelerator circuitry allows the use of
weaker DC pull-up currents while still meeting rise time
requirements, while the PCA9510 has no rise time accelerator
circuitry to prevent interference when there are multiple devices in
the same system. The PCA9510 and PCA9511 incorporate a digital
ENABLE input pin, which enables the device when asserted HIGH
and forces the device into a low current mode when asserted LOW,
and an open-drain READY output pin, which indicates that the
backplane and card sides are connected together (HIGH) or not
(LOW).
During insertion, the PCA9510 (IN only) and PCA9511 SDA and
SCL lines are precharged to 1 V to minimize the current required to
charge the parasitic capacitance of the chip.
The dynamic offset design of the PCA9510/11/12/13/14 I/O drivers
allow them to be connected to another PCA9510/11/12/13/14 device
in series or in parallel and to the A side of the PCA9517. The
PCA9510/11/12/13/14 can
not
connect to the static offset I/Os used
on the PCA9515/15A/16/16A/17 B side and PCA9518.
APPLICATION
cPCI, VME, AdvancedTCA cards and other multi-point backplane
cards that are required to be inserted or removed from an
operating system.

prevents SDA and SCL corruption during live board insertion and
