LS1028A RDB interposer

[mkraj]

Dear Team

We are doing a new board design with LS1028A. We want to  remove the complete interposer interface from the existing reference board. 

We want to delete complete interposer CFG_LS1043INT_RCW_SRC1,2,4,5,6,7 signals and corresponding circuit.

Is it ok?

We want to use in Only LS1028A mode only.

Thanks in advance.

With Regards

Yes, you can use only the LS1028A mode by removing the interposer part. You can also remove the CFG_LS1043INT_RCW_SRC1, 2, 4, 5, 6, 7, and CFG_LS1043INT_DRAM_TYPE signals from the CPLD.
