[FAQ] AM62D-Q1 Custom board hardware design – Collaterals to Get started

Hi Board designers, 

AM62D-Q1 processor family is available on TI.com and is in preview.

The below links are a quick reference to the collaterals that can be referred when starting a custom design.

Design Simulation files

https://www.ti.com/product/AM62D-Q1#design-tools-simulation

Simulation files provided includes IBIS, IBIS-AMI, BSDL, Thermal model and power-estimation tool (PET)

AM62D-Q1 PDN Target impedance values:(Same as AM62Ax)

For frequencies above 50 MHz the board decoupling caps do not play a critical role. SoC and Package decaps (if any) will be dominant beyond 50 MHz

Note: We do not include Buck output inductance in PDN simulations.

Note 1: For VDDS_DDR: we do not recommend using target impedance as the signoff..
Refer to the AM62Ax, AM62Px, AM62Dx LPDDR4 Board Design and Layout Guidelines which outlines all details of power aware SI/PI simulations that need to be run. The eye mask checks from these power aware simulations are the signoff.
