MIG Zynq LPDDR2 - Incorrect indication of pullup terminator to VTT for CKE pin on UG933 (v1.3).
On page 60 of the Zynq-7000 SoC PCB Design Guide (UG933 v1.3), LPDDR2 CKE termination is changed to pulldown from pullup to VTT.
Why is there a change?
Should CKE be terminated?
This is a documentation error.
CKE should only have a pullup to VTT for DDR3.
For LPDDR2 it should have a pulldown on CKE, not termination to VTT.
