| | 7 | = FMC-RF-2X245 User Guide: FMC HPC Interface = |
| | 8 | |
| | 9 | The FMC-RF-2X245 module is designed (with a few deviations, explained below) to the [http://www.vita.com/fmc.html VITA 57.1 FMC] specification. |
| | 10 | |
| | 11 | The FMC-RF-2X245 module is designed primarily for use in the FMC slot on WARP v3 kits. When modified for local clocking, the FMC-RF-2X245 module should work with other FPGA boards implementing an FMC HPC slot. The details below will help determine compatibility with third-party FMC carrier. |
| | 12 | |
| | 13 | == Power == |
| | 14 | The FMC-RF-2X245 module draws all its power from the FMC carrier. The require power supplies are: |
| | 15 | ||= FMC Net =||= Supported Voltages =|| |
| | 16 | || 12P0V || 12.0v || |
| | 17 | || VADJ || 1.8v - 2.5v || |
| | 18 | || 3P3VAUX || 3.3v || |
| | 19 | |
| | 20 | Other power connections on the FMC-RF-2X245 module: |
| | 21 | * 3P3V is not used |
| | 22 | * 3P3VAUX is only used for the EEPROM |
| | 23 | * VIO_B_M2C is tied to VADJ, as all LA/HA/HB I/O use the logic level set by VADJ (nominally 2.5v on WARP v3 kits). |
| | 24 | * VREF_A_M2C/VREF_B_M2C are unconnected |
| | 25 | * PG_M2C is tied to PG_C2M |
| | 26 | |
| | 27 | == FPGA I/O == |
| | 28 | The FMC-RF-2X245 module uses I/O from the LA, HA and HB banks. However FMC signals HB20(n/p) and HB21(n/p) are unused, for compatibility with the WARP v3 HPC slot. |
| | 29 | |
| | 30 | == MGTs == |
| | 31 | The FMC-RF-2X245 module connects four of the FMC MGT interfaces to SATA connectors: |
| | 32 | ||= FMC DP =||= Header =|| |
| | 33 | || DP4 || J3 || |
| | 34 | || DP5 || J8 || |
| | 35 | || DP6 || J7 || |
| | 36 | || DP7 || J1 || |
| | 37 | |
| | 38 | Refer to the [wiki:../MGTs MGT page] of this guide for details on these interfaces and the MGT clocking options implemented on the FMC-RF-2X245 module. |
| | 39 | |
| | 40 | The remaining DP signals (DP[0:3], DP[8:9]) are unconnected on the FMC-RF-2X245 module. |
| | 41 | |
| | 42 | == Misc I/O == |
| | 43 | '''JTAG''': The FMC JTAG signals are not used by circuits on the FMC-RF-2X245 module. The module ties TDI to TDO (to complete the carrier JTAG chain). TCK and TMS are not connected. |
| | 44 | |
| | 45 | '''EEPROM''': A Microchip 24AA128 I2C 128KB EEPROM is connected to the FMC I2C signals (SCL, SDA). Refer to the [wiki:../EEPROM EEPROM page] of this guide for details on the default EEPROM contents. |
| | 46 | |
| | 47 | == Mechanical == |
| | 48 | All FMC-RF-2X245 modules are built with the MC-HPC-10 connector option (lead-free, HPC, 10mm stacking height). |
| | 49 | |
| | 50 | The FMC-RF-2X245 module dimensions are not strictly compliant with the mechanical specifications for FMC modules in VITA 57.1. |
| | 51 | |
| | 52 | The module dimensions are compliant in the region around the FMC connector, which is sufficient for mechanical compatibility with many FPGA carriers (including WARP v3). The module deviates from the standard at the other end of the board (near the SMA connectors). The FMC-RF-2X245 module is a simple rectangular PCB, while the FMC standard specifies a more complex shape which narrows at the connector end. |
| | 53 | |
| | 54 | The deviations from the FMC outline specifications are not an issue when using this module on WARP v3 kits, nor on most other FMC-equipped FPGA development platforms we have seen. However the drawing below should be carefully considered before using the FMC-RF-2X245 module on a third-party FMC carrier. |
