[FAQ] DP83TC813R-Q1: DP83TC813 reset pin state during power-up

What should be the state of RESET_N be during DP83TC813's power-up sequence?

The state of RESET_N during the DP83TC813's power-up sequence generally does not matter and will not affect PHY functionality. However, if any power supply (excluding VSLEEP) has a ramp rate longer than 8 ms, a RESET pulse is required after the last supply becomes stable.
