Part Number: AM67A
Hi,
This question is related to following thread.
Following thread has already closed so I re-posted this as related question.

Let me confirm exact frequency range of each "Low", "Mid" and "High" freq for your attached table.
According to following pdf, these are defined as shown below.
Microsoft Word - J7_SoC_PCB_PI_Rcmds_v0.16.docx
Notes:
1). Low Freq range: Buck Fsw/10 (~0.2 -0.44) MHz < LF < 1.0 MHz
2.) Mid Freq range: 1.0 MHz < HF < 20 MHz
3.) High Freq range: 20 MHz < HF < 50 MHz
4) Max routing resistance from regulator to point of load at remote sense feedback to compensate~7.5% supply drop.
Target impedance value is a little bit different from above pdf, however can we apply same contents of above note for your attached table ?
Best Regards,
