| | 36 | None at the moment. |

| | 38 | ==== Changelog ==== |
| | 39 | |
| | 40 | |
| | 41 | * Fixed LED footprints |
| | 42 | * Added convenient .1" spaced headers for use with Phase 1 firmware. |
| | 43 | * Fixed TTS connections (both input and output) to match a traditional Ethernet Patch cable |
| | 44 | * Fixed the situation for the Oscillator, now that the datasheet has been understood and we know which pin needs to be enabled. Alternatively put OE on a FPGA pin (current solution is two sites for 603 resistors or solder shorts) |
| | 45 | * Added more labels (these labels are still valid in "old" designs) |
| | 46 | * Add soft reset button to implement TTC Phase 1 reset features (Low Active) |
| | 47 | * Added trigger button (Low active) |
| | 48 | * NIM Outputs added. |
| | 49 | * NIM Inputs added |
| | 50 | * Fixed the situation for the Oscillator, now that the datasheet has been understood and we know which pin needs to be enabled. Alternatively put OE on a FPGA pin (current solution is two sites for 603 resistors or solder shorts) |
| | 51 | * Added more label |
| | 52 | * Moved U2 from the M25P32''s SOIC16 package to its SO-8W package version |
| | 53 | * Added bypass capacitors to comparators U14, U15, U16 and U17 |
| | 54 | * Enlarged two holes on the SFP package to allow for easy fitting of the surface mount part. |

| | 67 | ==== Problems and Comments ==== |
| | 68 | |
| | 69 | * Pad of R5 connected to U4 needs to be shorted to the pad of R16 that is not connected to U4 |
| | 70 | |
| | 71 | * D1, D2, D3, D4, D5 and D6 are all backwards... datasheet was misread. DNP or put in 3mm LEDS cathode side towards the board edge. Its a tight fit. Preferably leads bent to point off the board |
| | 72 | |
| | 73 | * J3 DNP |
| | 74 | |
| | 75 | * R16, R5, R1 DNP |

| | 77 | === Firmware === |
| | 78 | |
| | 79 | Follows the specification set down in the [[TTC_TTS_FirmwareSpecification]] |
| | 80 | |
| | 81 | |
| | 82 | ==== SFP Interface ==== |
| | 83 | |
| | 84 | [[TTC_TTS_FirmwareSpecification]] |
| | 85 | |
| | 86 | The BiPhase Mark Code based SFP interface for the TTC data stream has been implemented. |
| | 87 | |
| | 88 | Rx Implemented. Tx not yet completely finished, Can take a predetermined data stream and send it out... |
| | 89 | |
| | 90 | ==== TTS RJ-45 Outputs ==== |
| | 91 | |
| | 92 | Channel A displays top 4 bits of a Broadcast command sent from the AMC13. This has been tested. Currently a problem with the TTC Gadget''s RJ45 outputs, which will be fixed in future revisions. For now use a [https://docs.google.com/drawings/pub?id=1z7iB2nHYvPc0fIcee3giTS-gFnTEbgTqFwxoy7Ys3kI&w=668&h=508 Custom RJ45 Crimps (view is from the shiny gold crimp side of the connectors)] |
| | 93 | |
| | 94 | Channel B displays the bottom 4 bits of a broadcast command. This is currently unused. |
| | 95 | |
| | 96 | Tested by sending the output of the TTS to the TTS Test Gadget and reading out its buffer. To write to the AMC13 broadcast command test register first clear register 1 (wv 1 0) then set the 12th bit and put your ttc command into bits 8-11 (wv 1 0x1n00), where is n is hex between 0 and F. |
| | 97 | |
| | 98 | ==== Ethernet Interface/IPBus ==== |
| | 99 | |
| | 100 | The [[OEthernetMac]] |
| | 101 | |
| | 102 | Successfully talking Ethernet Interface with IPBus interface. |
| | 103 | |
| | 104 | The 100Mb/s Ethernet Mac is now functional on both the Digilent Nexys3 board and the CMS TTC/TTS Adapter Board (Rev. A). |
