Hi There,
The documentation provides recommended routing requirements.
(Table 21. i.MX 8M Mini LPDDR4-3000 routing recommendations)
Only DQS ± 10ps is recommended for the data byte lane.
However, Table.23 can be found within 1ps in the data group.
Does the data group need to match within 1ps like CLK / DQS?

Hi @okamotosatoshi,
Yes, As per Table-21, we need to match within +/-10ps, but if we are able to match within 1ps then it is the best. It is recommended too.
