AM335X Schematic checklist中关于DDR3的描述，使用单颗16bit的DDR3，不需要VTT Termination.

For point-to-point DDR3 topologies (e.g. single x16 DDR3 IC), VTT termination is not needed.

• If not using VTT termination, VREF should be obtained using a resistor divider (10Kohm 1%) with capacitive decoupling to ground, and should be used as a reference for both CA and DQ pins on the memory, as well as the VREF signal on AM335x. Be sure to use high precision (1%) resistors as specified in the datasheet. When not using VTT, be especially sure to follow the routing guidelines in the datasheet.

但是我看到tmdssk3358_3h30009_rev1_2b这份参考图（sprr356.pdf）里面，DDR3还是有加TPS51200转出VTT,并有加VTT Termination.

然而在BeagleBoneBlack_C这份图里面，没有加VTT Termination.

请问使用单颗16bit的DDR3，是否需要TPS51200转出VTT,并加VTT Termination吗？
