I am creating the schematics that are similar to the BPi-M2M board.
1) Bypass Caps - I see values in the schematic that are 22uF, 4.7uF, 1.0uF,
and then 104. What value is 104????
2) I am using an average dielectric like FR-4. Routing topology for DDR3
has critical length matching for Point-to-Point:
a) I am surprised there there are no termination resistors - is that
taken care of by ODT?
b) I am assuming 40ohms for DDR3 Single Ended and 80 ohms for the
Differential clocks?
c) Delay match are DQ/DM to DQS_P/N in data group, and
Address/Control to CK_P/N?
d) Could you provide the pin delays for the R16? (wire delays inside
chip from bare die to package pins)
Regards,
Craig
