Product Description
The CMCPCI102B is a 10-channel backplane interface/
termination IC specifically designed for CompactPCI
redundant system-slot cards. The CMCPCI102B allows
CompactPCI boards to interface to the backplane and
provides the versatility to use system cards in any slot
(system or peripheral). Per the CompactPCI specifica-
tion, the CMCPCI102B provides a 10
termination
resistor for each channel to terminate the transmission
line stub on the board. An integral series switch and
associated control signal (SW_EN) permits connection/
disconnection of the channel, so that the device side of
the circuit may be isolated from the backplane side.
The CompactPCI standard requires system boards to
be hot-swappable. To accommodate this requirement,
the CMCPCI102B features a switched 10k
resistor
connected to the 1V Precharge Supply Voltage. If the
precharge enable pin (P_EN) is asserted, then the 10k
pull-up resistors are connected to precharge the cir-
cuits.
In addition, a system board requirement mandates
either a 1.0k
pull-up resistor or a 2.7k
resistor con-
nected to VIO. CompactPCI slot cards must work in
either 3.3V or 5V systems, hence the need for both
2.7k
and 1k
resistors. If the 3_EN pin is logic high,
the 2.7k
resistor is used as the pull-up. If the 5_EN pin
is logic high, the 1k
resistor is used.
The CMCPCI102B integrates all these functions in a
low-profile 28-pin TSSOP package.
