7.1.2.14.1.2 CK and ADDR_CTRL Routing, Four DDR3L Devices

Figure 7-8 shows the CK routing for four DDR3L devices placed on the same side of the PCB. Figure 7-9 shows the corresponding ADDR_CTRL routing.

66AK2G12 addr_ctrl_routing_4_single_sprs614.gifFigure 7-9 ADDR_CTRL Routing for Four Single-Side DDR3L Devices

To save PCB space, the four DDR3L memories may be mounted as two mirrored pairs at a cost of increased routing and assembly complexity. Figure 7-10 and Figure 7-11 show the routing for CK and ADDR_CTRL, respectively, for four DDR3L devices mirrored in a two-pair configuration.
