## FMC mezzanine cards
|
|
|
|
|
|
1. EEPROM: GA1 should connect to A0, GA0 should connect to A1
|
|
|
1. An FMC mezzanine should have a specific EEPROM (24AA64T-I/MC.
|
|
|
2. EEPROM: GA1 should connect to A0, GA0 should connect to A1
|
|
|
(Observation 5.22 [ANSI/VITA 57.1
|
|
|
spec](http://cdsweb.cern.ch/record/1172409?ln=en) - CERN only).
|
|
|
2. TDI and TDO are connected together if not used on the mezzanine.
|
|
|
3. Connect all mounting holes to ground (this is not in the
|
|
|
specification, but is the best practice).

3. TDI and TDO are connected together if not used on the mezzanine.
|
|
|
4. Have a note on the schematic about allowed Vadj level (e.g. most
|
|
|
carriers on ohwr can provide only 2V5).
|
|
|
5. Foresee decoupling capacitors near the FMC connector (allowing power
|
|
|
pins to work as signal return too).
|
|
|
6. Connect all mounting holes to ground (this is not in the
|
|
|
specification, but is the best practice).
|
|
|
7. Consider using a thermometer/unique ID IC (DS18B20U+) as is used on
|
|
|
most OH FMC designs (this is not in the specification, but is the
|
|
|
best practice).
