Hi,

 

In ADSP-BF609 EZ-Board SCHEMATIC (Board number: A0269-2011, rev: 1.0), three regulators are used (3.3V, 1.8V and 1.25V) in sheet 16:

1. We do not understand what is the use of D1, D3 and D4 diodes and they look be overrated (10-12V for 3.3V, 1.8V, 1.25V).

2. We do not understand what is the role of D6, D7 and D8 diodes.

 

Thanks.
