The TPCE261 is a standard height PCI Express Revision 2.0 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 TPCE261 is a versatile solution to upgrade well known PMC I/O solutions to the PCI Express signaling standard.
On the PCI Express side, an x1 link with 2.5GT/s speed to the host board is provided.
The bridging between the system host board and the PMC slot is handled by the transparent PCIe-to-PCI Bridge XIO2001 from Texas Instruments.
On the PMC side, PCI signaling voltages of 3.3V (TPCE261-x1R) and 5V (TPCE261-x0R) are supported. 32-bit PCI accesses are possible with 33MHz or 66MHz.
The TPCE261 supports PMC front-panel I/O and also PMC P14 Rear-I/O through a 68-pin ERNI SMC 1.27mm flat cable connector.
The PCIe edge card connector provides +12V and +3.3V. All TPCE261-xx variants do not use the +3.3V at all. The TPCE261-1xR 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 TPCE261-1xR.
For PMC modules with increased power requirements, the TPCE261-2xR offer an additional 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.
