7.7.2.3

DDR3 and DDR3L Routing Guidelines

NOTE

All references to DDR3 in this section apply to DDR3 and DDR3L devices, unless otherwise
noted.

7.7.2.3.1 Board Designs

TI only supports board designs utilizing DDR3 memory that follow the guidelines in this document. The
switching characteristics and timing diagram for the DDR3 memory interface are shown in

Table 7-56

and

Figure 7-46

.

(1) The JEDEC JESD79-3F Standard defines the maximum clock period of 3.3 ns for all standard-speed bin DDR3 and DDR3L memory

devices. Therefore, all standard-speed bin DDR3 and DDR3L memory devices are required to operate at 303 MHz.

7.7.2.3.1.1 DDR3 versus DDR2

This specification only covers AM335x PCB designs that utilize DDR3 memory. Designs using DDR2
memory should use the DDR2 routing guidleines described in

Section 7.7.2.2

. While similar, the two

memory systems have different requirements. It is currently not possible to design one PCB that meets
the requirements of both DDR2 and DDR3.

7.7.2.3.2 DDR3 Device Combinations

Since there are several possible combinations of device counts and single-side or dual-side mounting,

Table 7-57

summarizes the supported device configurations.

Two DDR3 devices are mirrored when one device is placed on the top of the board and the second device is placed on the bottom of
the board.
