Trigger Interface (TI) and Trigger Distribution (TD) Combined Function Board
William presented his concept for a combined TI/TD board, an alternative to our original plan to have separate TI and TD boards.
- H-D needs about 70 TI boards and 16 TD boards.
- Easy to fit all functionality on one board.
- Populate differently for different applications.
- Can act as a Trigger Supervisor (TS) for small systems.
- Front-panel space at a premium.
- Fiber transceivers are the driving cost at $500 each.
- Can have 1 to 8 fiber transceivers.
- Not all possible TI and TD configurations will work if you want TS functionality as well or want 8 transceivers.
In general, the engineers think this is the way to go whereas the physicists are dubious about introducing additional complexity compared to two simpler board designs. An important question is how much does the TI version cost compared to a dedicated TI board, since we need many more TI's than TD's.
