operating frequency question

This behavior indicates you have board design issue related to AVS power supply.If core is clocked at lower frequency it will draw less current and crash indicates board design is not able to provide required current to the device.

hi SuperMan-Badri,

thanks for your reply.

In our design,  the output of AVS power is up to 12 Amp and we have followed as below

1. connect sense line to 8168 BGA ball

2. Power planes use 1.0Oz for it(AVS POWER)

3. Add 100pF、1000pF decoupling capacitance for AVS power

Basically the current should be enough.

Is there anything I miss??
