The table below describes the DQ and CB wiring information for each SDRAM on the DIMM. Note that the
DQ wiring is different from that described in the Block Diagram.
Note:
Transmission Lines (TL) are represented as cylinders and are labeled with length designators. These
are the only lines that represent physical trace segments. For more detailed topology information please
refer to the DDR SDRAM Registered DIMM Design Specification.

1. These numbers can be associated with the corresponding DIMM tab pin by referencing the DIMM connector pinout on pages 2
and 3 of this document. Example: DQ7 at the DIMM tab (pin 99) is wired to SDRAM device position D0, pin 5 and D9, pin 62.
