Hi Damien,

Unless Pierrick asked you already, we are looking for options of reducing the HGCROC power budget for HRPPD application. Would anything like this be possible / help:

(1) disable channels 64..71 (or 65..71)

(2) disable TOT functionality

(3) disable trigger functionality entirely (now we simply assume the trigger outputs are ignored?)

Anything else? Presently we assume ~15 mW/ch ball park number (including shared circuitry) times 72, which is ~1.1W / ASIC. How far down can one go disabling the unused stuff?

Cheers,

Alexander.
