PCI Express x4, Gen3 XMC Carrier

TPCE278-11R

Application Information

The TPCE278 is a standard height PCI Express Revision

3.0 compatible module that provides one slot for a single-

width XMC 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 TPCE278 is a versatile solution to upgrade well

known XMC I/O solutions to the PCI Express signalling

standard.

The PCI Express x4 link from the host board to the XMC

module is enhanced by a PCIe Gen3 Redriver, allowing

safe operation of XMC modules on PCIe mainboards.

VPWR is selectable via order option. The TPCE278-x0R

variants provide 12V VPWR and the TPCE278-x1R order

options provide 5V VPWR.

The TPCE278 supports XMC front panel I/O, and also P14

and P16 rear I/O independently.

XMC P14 rear I/O is provided through a Tyco AMPMODU

System 50 0.050x0.100 flat ribbon cable connector. The

I/O lines are routed differentially.

XMC P16 rear I/O is implemented through two Samtec

QTH-DP 0.50mm Q Pairs® High Speed Ground Plane

Socket Strip, Differential Pair connector providing access

to all P16 I/O lines.

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

The TPCE278-1xR uses the +12V of the PCIe edge card

connector to generate all power supply voltages for the

XMC slot (+3.3V, VPWR and +12V).

According to the PCIe specification, a PCIe x4 card is

allowed to use 25W on the +12V which allows to operate

most of the available XMC modules on the TPCE278-1xR.

For increased power requirements of an XMC module, the

TPCE278-2xR offer a PCIe Graphics Power Connector to

supply the +12V for generating all the power supply

voltages for the XMC slot providing power of up to 75W.

A 10-pin JTAG header is available for XMC module

debugging purposes. All five JTAG signals are routed

directly to the XMC slot.
