Tool/software:
Dear Team,
We are using AM6442 in one of our designs, where we are using LPDDR4 interface.
For LPDDR4 interface we are planning to set the Single Ended Impedance as 48Ohms. Though the TI recommendation is to have 40Ohms as per AM64x\AM243x DDR Board Design and Layout Guidelines.
The reason behind the 48Ohms is: Since the 40Ohm impedance requires wider track width, with this getting 2x spacing is difficult in our board. Hence, we are choosing 48Ohms for the ease of routing.
Kindly provide your thoughts/comments on the same to proceed further.
Note: As we are planning to start the routing activity on 10/02/2025 it would be helpful if we get your comments at the earliest.
Thank you.
Regards
Amarnath G
