7.6 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.
