Signal Groups
Signals are grouped by buffer type and similar characteristics as listed in
Table 7-3
. The
buffer type indicates which signaling technology and specifications apply to the signals.
All the differential signals, and selected DDR3 and Control Sideband signals have On-
Die Termination (ODT) resistors. There are some signals that do not have ODT and
need to be terminated on the board.
