1 Product Description

The TPCE280 is a standard height, half length 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 PCI Express x8 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.

The voltage level for the XMC’s main power supply, VPWR, is selectable via order option. The TPCE280-

x0R variants provide 12V VPWR and the TPCE280-x1R order options provide 5V VPWR.

The TPCE280 supports XMC front panel I/O, and also P14 and P16 rear I/O independently.

XMC P14 Rear-I/O is offered through an 68-pin ERNI SMC, right angle male, 1.27mm pitch connector. The

I/O lines are routed differential.

XMC P16 Rear-I/O is implemented through two Samtec Firefly UCC8 and UEC5 connectors providing

access to the P16 I/O lines.

The TPCE280 provides a fan mounted under the XMC slot that helps cooling the system. This fan does not

occupy a second PCIe slot as most other carrier solutions do.

The PCIe edge card connector provides +12V and +3.3V. The TPCE280-1xR uses only 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 x8 card is allowed to use 25W on its +12V supply which allows to

operate most of the available XMC modules on the TPCE280-1xR. For XMC modules with increased power

requirements, the TPCE280-2xR offer a PCIe Graphics Power Connector to supply XMCs with up to 75W.

A 14-pin 2mm JTAG header is available for XMC module debugging purposes. All five JTAG signals are

routed directly to the XMC slot.

3 Handling and Operating Instructions

ESD Protection

The TPCE280 is sensitive to static electricity. Packing, unpacking

and all other handling of the TPCE280 has to be done in an ESD/EOS

protected Area.

Installation of TPCE280-2xR

For the TPCE280-2xR variants, it is imperative to always connect a

PCI Express VGA power connector to the TPCE280, even if no XMC

is mounted.

TPCE280 User Manual Issue 1.0.3 Page 9 of 20

4 XMC Interface

Power

The TPCE280 can provide the following power supplies to the XMC:

VPWR (12V or 5V)

3.3V

+12V (optional XMC voltage, but always supplied by the TPCE280)

-12V (optional XMC voltage, available via order option)

As the ±12V supplies are optional and VPWR can be 12V or 5V, it depends on the TPCE280 order option

which supplies are available and what voltage level is provided as VPWR.

4.1.1 VPWR Tolerance

For all TPCE280 variants with VPWR = 12V, this voltage is directly connected to the 12V supply from the

system (either via PCIe edge connector or the PCIe VGA Graphics connector). The PCIe specification allows

for tolerances of ±8%, whereas the XMC specification allows only for ±5%.

This has to be taken into consideration when using these TPCE280 variants.

4.1.2 Power Limits for XMC Modules

The following current limits have to be taken into account when choosing the appropriate TPCE280 for the

power requirements of the XMC module.

Table 4-1 : Current Limits for the XMC Modules

*) System dependent: After power-up, the PCI-Express specification limits the total power

consumption of x8 PCIe Add-In Cards to 25W. If more power is needed, the XMC can request it

from the system via mechanisms defined in the PCI-Express specification.

Alternatively, a TPCE280 variant with PCIe Graphics Power Connector could be used.

In principle, an XMC could draw more than 100W. Since most XMCs tend to convert the delivered power into

heat, users should keep in mind that it needs appropriate system cooling solutions when such high power

XMCs are used.

TPCE280 User Manual Issue 1.0.3 Page 10 of 20

4.1.3 Stable Power Supply

All power supplies for the XMC slot are stable max. 5ms after the system power supply is stable.

Installation of an XMC Module

The XMC module has to be mounted on the TPCE280 prior to installation into the system.

Before installing an XMC module, be sure that the power supply for the TPCE280 is turned off.

TPCE280 and XMC are Electrostatic Sensitive Devices (ESD). Use an anti-static mat connected

to a wristband when handling or installing the components.

If the XMC has a front panel, first remove the cover from the XMC front panel cut-out of the TPCE280. Install

the XMC at an angle so that the XMC front panel pushes through the XMC front panel cut-out. Then rotate

down to mate with the XMC connectors on the TPCE280. If the XMC has no front panel, simply plug in the

XMC, and leave the cover in the XMC front panel cut-out of the TPCE280.

After the XMC module has been installed, it can be secured on the TPCE280 using the mounting screws that

come with the XMC module. There are four screw mounting locations, two at the XMC front panel and two at

the standoffs near the XMC bus connectors.

According to the XMC specification, VPWR can be 5V or 12V, and it is up to the XMC to deal with both

power supply voltage levels.

Nevertheless, there are some XMCs on the market that work only with VPWR = 5V, sometimes with

remarkable and non-reversible effects when they are powered with VPRW = 12V.

For those XMCs, a special TPCE280 variant with VPWR = 5V is available. Always check if your XMC

supports the VPWR voltage of the TPCE280 variant used.

For all TPCE280 with VPWR = 12V, this voltage is directly connected to the 12V supply from the PCIe

connector. The PCIe specification allows for tolerances of ±8%, whereas the XMC specification allows only

for ±5%. This has to be taken into consideration when using these TPCE280 variants.
