Product Description
The CMCPCI102BT/BR is a 10-channel backplane
interface/termination IC specifically designed for Com-
pactPCI
redundant
system-slot
cards.
The
CMCPCI102BT/BR 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 specification, the CMCPCI102BT/
BR provides a 10Ω termination resistor for each chan-
nel 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 CMCPCI102BT/BR features a switched 10kΩ resis-
tor connected to the 1V Precharge Supply Voltage. If
the precharge enable pin (P_EN) is asserted, then the
10kΩ pull-up resistors are connected to precharge the
circuits.
In addition, a system board requirement mandates
either a 1.0kΩ pull-up resistor or a 2.7kΩ resistor con-
nected to VIO. CompactPCI slot cards must work in
either 3.3V or 5V systems, hence the need for both
2.7kΩ and 1kΩ resistors. If the 3_EN pin is logic high,
the 2.7kΩ resistor is used as the pull-up. If the 5_EN pin
is logic high, the 1kΩ resistor is used.
The CMCPCI102BT/BR integrates all these functions in
a low-profile 28-pin TSSOP package and is available
with optional lead-free finishing.
