MIG 7 Series LPDDR2 - maximum performance has been lowered to 667 Mb/s

Description

7 Series MIG IP for LPDDR2 maximum performance has been changed from original estimate of 800 Mb/s down to 667 Mb/s.

Solution

LPDDR2 does not use a DLL to track the input clock which leads to higher variation on DQS and DQ timing. LPDDR2 MIG IP maximum performance has been set to maximum 667 Mb/s to account for the higher variation.
