Hi,
Please read section 5.13.8.2 in the AM437x Datasheet Rev. D. Check Figure 5-50 and pay special attention comments about it in section 5.13.8.2.1.3.10.
Hi Brad,
The balanced line topology with two 16-bit DDR3 memory devices that do not have VTT termination on the address and control signals seems to be used in AM437x Starter Kit, but this topology is not supported in AM437x datasheet (SPRS851B).

Part Number: AM4379 For the following reference design http://www.ti.com/tool/TIDEP0012 Customer is looking for:
1. In Allegro .alg format to allow import into Altium
2. Design and layout guideline for T-Topology design
3. Guidance on configuring…

Hi team,
We are using AM4377 processor in one of our designs. We are designing the memory with 2 DDR3 chips, 13-bit address lines(MT41K64M16TW-107 IT). We are planning to route in Tree topology to avoid cost of termination regulator…
Hi Bob,
It's a bit outside of my expertise, you may have better luck posting on the non-isolated DC/DC forum ( https://e2e.ti.com/support/power_management/non-isolated_dcdc/ ). Something like the TPS51206 could work, though it may be overkill. Alternatively…
Hi,
Even our customer wants to design their boards without DDR3 VTT termination in order to save board space & cost.
Could you please let us know if there is anything else to be considered while designing DDR3 without VTT termination.
It would be…
Hi, the AM437x Starter Kit is not released yet hence not supported. You will find a few TI designs based on it (TIDEP0012, TIDEP0013, TIDEP0016) but the board is not available yet.
Hi Biser, I'm sorry but I'm not sure if I can refer TIDEP0012 "DDR3 Reference Design without VTT termination using AM437x" or not. Because there is no infomation about the connection "32-Bit DDR3 Interface Using Two 16-Bit DDR3 Devices Without VTT Termination…
