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 XMCs 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.
