Part Number: AM64X-ADVANCE-SW

Hi,

May I have the propagation delay in length information for AM6442BSFFHAALV?
I need it for DDR trace length matching.

Best Regards,

Please review the AM64x DDR layout guidelines: https://www.ti.com/lit/pdf/spracu1

Propagation delay information, along with a lot of other DDR related board info for Sitara products, can be found here: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1310171/faq-am625-am623-am620-q1-am62l-am62ax-am62d-q1-am62px-am64x-am243x-alv-design-recommendations-commonly-observed-errors-during-custom-board-hardware-design-ddrss-ddr4-lpddr4-memory-interface#:~:text=Pin%20delay%20references%3A-,AM64x%20/%20AM243x%20(ALV),-/cfs%2Dfile/__key
