FB-DIMM Channel Schematic
A FB-DIMM channel consists of 14 unidirectional differential signal pairs referred to as
the Northbound path, 10 unidirectional differential signal pairs referred to as the
Southbound path, and a differential reference clock.
NOTE: The northbound signal pairs are enumerated from 0 to 13. Signal pair 13 is not
active but must be connected to properly terminate the FB-DIMM channel. See
sections,
Branch 1” on page
The southbound path is used to convey DIMM commands and write data to the
addressed DIMMs. The northbound path returns read data and status from the
addressed DIMM.
The northbound and southbound paths are used to convey FB-DIMM frames that are
synchronized to the reference clock. Each frame consists of 12 data transfers.
Southbound frames contain a payload of 8 bytes per frame per channel. Northbound
frames contain a payload of 16 bytes per frame per channel.
