Purpose | Drawings / Other Documentation |
| 0001 | Several J26 outputs used as strobes to access various board resources need to be synchronous with DSP clock H3. |
|
|
|
Eliminate 24nSec Clock Noise on L2A pin of TDC chips 0-7 |
|
|
|
Correct a power-up condition which could cause buffer chips P2, PQ6 to destruct. | |
|
|
Correct a board reset condition which could cause buffer chips P2, PQ6 to destruct. | |
|
|
Replace Q3 component which has known defect which can cause TDC boards to hang the VME bus. | |
|
|
Glitch on RD_SRAM* output of J26 during VME reads can result in corrupted data to be read. | |
|
|
Correct a board design error which can result in incorrect data to be read from the VME FIFO during a DSP write cycle. | |
|
|
To prevent erroneous bunch crossing register values caused by noise pick-up on signal L1_ACCEPT_12 from WIRE_DATA signals. | |
| 0009 | Provide sufficient drive current for DSP data and address lines. |
