PCI Express PMC Carrier

TPCE260-10R

Application Information

The TPCE260 is a standard height PCI Express Revision

1.1 compatible module that provides one slot for a single-

width PMC module used to build modular, flexible and cost

effective I/O solutions for all kinds of applications like

process control, medical systems, telecommunication and

traffic control.

The TPCE260 is a versatile solution to upgrade well

known PMC I/O solutions to the PCI Express signalling

standard.

The bridging between the PCI Express x1 link to the host

board and the PCI bus signals to the PMC slot is handled

by the transparent PCIe-to-PCI Bridge PI7C9X111SL from

Pericom.

The PCI bus side of the bridge allows 32-bit PCI accesses

with either 33 MHz or 66 MHz. Both 3.3V (TPCE260-x1R)

and 5V (TPCE260-x0R) PCI I/O signalling voltages are

supported.

The TPCE260 supports PMC front panel I/O and also

PMC P14 Rear I/O through a VME P2 style connector

(IEC 60603-2, Type C). The I/O mapping of P14 complies

with VITA-35 (“PMC P4 to VME-P2, Rows A-C mapping”).

The PCIe edge card connector provides +12V and +3.3V.

All TPCE260-xx variants do use the +3.3V solely to power

the PCIe-to-PCI Bridge.

The TPCE260-1xR uses the +12V of the PCIe edge card

connector to generate all four power supply voltages for

the PMC slot (+3.3V, +5V, +12V and -12V).

According to the PCIe specification, a PCIe x1 card is

limited to 6W on the +12V which allows to operate most of

the available 32-bit 33/66 MHz PMC modules on the

TPCE260-1xR.

For increased power requirements of a PMC module, the

TPCE260-2xR offer a PCIe Graphics Power Connector to

supply the +12V for generating all the power supply

voltages for the PMC slot providing a power of up to 25W.
