6.11.3.11 DDR2/mDDR CK and ADDR_CTRL Routing

Figure 6-23 shows the topology of the routing for the CK and ADDR_CTRL net classes. The route is a balanced T as it is intended that the length of segments B and C be equal. In addition, the length of A should be maximized.

(1) Series terminator, if used, should be located closest to device.
(2) CACLM is the longest Manhattan distance of the CK and ADDR_CTRL net classes.
(3) Center to center spacing is allowed to fall to minimum (w) for up to 500 mils of routed length to accommodate BGA escape and routing congestion.
(4) w = PCB trace width as defined in Table 6-29.

Figure 6-24 shows the topology and routing for the DQS and D net class; the routes are point to point. Skew matching across bytes is not needed nor recommended.

(4) Center to center spacing is allowed to fall to minimum (w) for up to 500 mils of routed length to accommodate BGA escape and routing congestion.
(5) D's from other DQS domains are considered other DDR2/mDDR trace.
(6) w = PCB trace width as defined in Table 6-29.
