IMX7D to LPDDR3 interface clock termination

logeshs — Tue, 26 Dec 2017 14:54:59 GMT

Hi,

We are using MCIMX7D3EVK10SD in our design with 08EMCP08-EL3DT227-A01U (Kingston Memory) using LPDDR3 interface.

Kindly suggest what type termination need to be provided for DDR_Clock in LPDDR3 interface. I could not find any recommendation for DDR_Clock Termination and in WARP board design no termination was used. Kindly suggest suitable termination or shall we connect as such in WARP schematics design.

Thanks & Regards,

Logesh

Hi Logesh

please refer to sect.3. i.MX7 series layout recommendations Hardware Development

Guide for i.MX7Dual and 7Solo Applications Processors, termination is not used.
http://www.nxp.com/files/32bit/doc/user_guide/IMX7DSHDG.pdf

In general recommended to perform signal integrity (SI) simulations.

Best regards
igor
