7.7.2.2.3 DDR2 CK and ADDR_CTRL Routing

Figure 7-44

shows the topology of the routing for the CK and ADDR_CTRL net classes. The length of

signal path AB and AC should be minimized with emphasis to minimize lengths C and D such that length
A is the majority of the total length of signal path AB and AC.

(1) CK represents the clock net class, and ADDR_CTRL represents the address and control signal net class.

(2) Series terminator, if used, should be located closest to the AM335x device.

(3) Differential impedance should be Zo x 2, where Zo is the single-ended impedance defined in

Table 7-46

.

(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) CACLM is the longest Manhattan distance of the CK and ADDR_CTRL net classes.

Figure 7-45

shows the topology and routing for the DQS[x] and DQ[x] net classes; the routes are point to

point. Skew matching across bytes is not needed nor recommended.
