1. In the DM368 EVM , they have put 22ohm termination in DDR CLK signal where Datasheet recommend 10 ohm maximum. Please suggest what should be followed?
2. Datasheet had made net classes for DDR signals and DDR_DQMx signal fall in DQS net class. According to Table 6-34. termination should be close to DDR but this signal is output from DM368 SoC so termination resistor should be placed close to DM368.
Please clarify the above points.
Thanks
