AM62P: About LPDDR4 layout using AM62P

Part Number: AM62P

Tool/software:

Hi team,

I am currently designing the PCB layout using the AM62P.

This PCB has an LPDDR4 device installed.

Therefore, I have two questions regarding the LPDDR4 layout:

1. According to the "AM62Ax, AM62Px, AM62Dx LPDDR4 Board Design and Layout Guidelines",
I understand that the recommended routing specifications for the LPDDR4 interface are listed in Table 2-6 and Table 2-7.
For what operating clock frequency are these routing specifications defined?

2. When using an LPDDR4 device operating at 1600 MHz, what are the corresponding values in Table 2-6 and Table 2-7?

Thank you for your support.

  • The guidelines in the app note will apply to all supported LPDDR4 frequencies for AM62P.  You can use these guidelines for your device operating with 1600MHz memory clock speed.  By following these guidelines, the DDR controller/PHY can successfully perform initialization and training on the LPDDR4 interface  

    Regards,

    James
