A single standard, mid-size or full-size AMC.1 module from TEWS Technologies conforms to MTCA.4 (Micro TCA enhancements for rear I/O and precision timing) with a user-programmable XC6SLX45T-2 or XC6SLX100T-2 Spartan-6 FPGA. The TAMC651 modules are designed for industrial, COTS, and transportation applications, where specialised I/O or long-term availability is required. The Spartan-6's integrated PCIe endpoint block is connected to AMC port four. AMC ports 12-15 (point-to-point) and AMC ports 17-20 (multi-drop) connect to FPGA I/O pins via on-board M-LVDS transceivers. One of the FPGA's GTP transceiver uses an SFP interface available at the front plate. SFP support signals are available as FPGA I/O pins. Four FPGA controlled LEDs are also available at the front plate. According to the MTCA.4 specifications, the module provides two 30-pair ADF connectors at the rear I/O. There are also 46 differential FPGA I/O lines, two differential reference clock lines, two Spartan-6 GTP transceivers. The differential FPGA I/O lines could also be used as single-ended I/O lines. The FPGA bank supply for I/O signals is 2.5V. There is also a 128Mbyte, 16bit wide DDR3 SDRAM bank. The SDRAM-interface uses one of the internal hardwired memory controller blocks of the FPGA. The FPGA is configured by a flash device, which is programmable via a JTAG header.
