Schematics Review Oct 2016
The following topics were discussed. The corresponding issues have also been created.
1) Make the project hierarchical by adding a top
level
2) Change the OHL Copyright CERN 2014 to Copyright
CERN 2014-2016
3) Rename Power Supply +5V to P5V, -5V to M5V
etc
4) To avoid potential damage of the ADC, ensure by hardware means that
+5V and -5V for the ADC front end are switched on
simultaneously
5) No indication of protection diode inside of the G6K-2F-Y-3VDC
relays. Protection diode is missing and T4 T6 can be
damaged
6) Remove completely EXT_SYNC_TST_N signal along with associated
T1, R1
7) Replace 31.25Kbps R29: 332 Ohm 0.1% -> 330
Ohm 1%
8) Remove unused ADC_OUT3, ADC_OUT4 pins from ADC
IC
9) Replace D8 with a BAV99
