Application Information
The TPCE275 is a standard height PCI Express Revision 1.1 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 TPCE275 is a versatile solution to upgrade well known XMC I/O solutions to the PCI Express signalling standard.
The PCI Express x1 link from the host board to the XMC module is enhanced by a PCIe Redriver, allowing safe operation of XMC modules on PCIe mainboards.
VPWR is selectable via order option. The TPCE275-x0R variants provide for 12V VPWR and the TPCE275-x1R order options provide 5V VPWR.
The TPCE275 supports XMC front panel I/O, and also P14 and P16 rear I/O independently.
XMC P14 rear I/O is provided 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”).
XMC P16 rear I/O is provided through two 50-pin flat cable connectors mounted in a 2.54mm grid.
The PCIe edge card connector provides +12V and +3.3V. The TPCE275-1xR 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 x1 card is limited to 6W on the +12V which allows to operate many of the available XMC modules on the TPCE275-1xR. For increased power requirements of an XMC module, the TPCE275-2xR 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 25W.
A 10-pin JTAG header is available for XMC module debugging purposes. All five JTAG signals are routed directly to the XMC slot.
