Design Guidelines - DDR3 Termination

These rules apply to termination for DDR3 SDRAM:



Unidirectional signals are to be terminated with the memory device’s internal
termination or a pull-up of 40Ω to VTT at the load. A split 80Ω termination to

VCCO and an 80Ω termination to GND can be used, but takes more power.

For bidirectional signals, the termination is needed at both ends of the signal

(DCI/ODT or external termination).



Differential signals should be terminated with the memory device’s internal

termination or a 80Ω differential termination at the load. For bidirectional

signals, termination is needed at both ends of the signal (DCI/ODT or external

termination).



All termination must be placed as close to the load as possible. The termination

can be placed before or after the load provided that the termination is placed
within a small distance of the load pin. The allowable distance can be

determined by simulation.



DCI can be used at the FPGA as long as the DCI rules such as VRN/VRP are

followed.
