DP83TC811S-Q1: T5.2 and osc questions

Hello Amelie,

Amelie Zheng said:

Is T5.2 time difference between VDDIO and VDDA?

Yes, T5.2 is the time difference between when VDDIO and VDDA cross 50% of their intended voltage level.

Amelie Zheng said:

Whether this osc is situable for 811?

We would recommend a device that has a 50 Ohm ESR or lower. This is due to concerns that the oscillating system may not start up. More information can be found in section 3.8 here.

Sincerely,

Gerome
