Chapter 1: AC701 Evaluation Board Features
The AC701 board DDR3 memory interface adheres to the constraints guidelines
documented in the DDR3 Design Guidelines section of the 7
Series FPGAs Memory Interface
Solutions User
Guide (UG586) [Ref 3]. The AC701 board DDR3 memory interface is a 40 Ω
impedance implementation. Other memory interface details are available in the
7
Series FPGAs Memory Interface Solutions User Guide (UG586) and the 7 Series FPGAs
Memory Resources User
Guide (UG473) [Ref 4]. For more DDR3 SODIMM details, see the
Micron MT8JTF12864HZ-1G6G1 data sheet [Ref 15].
