Hi,
For TUSB7320, ask the following questions.
① What kind of terminal has AUX_DET function?
② What is the power supply for VDDA_3P3?
③ The resistance between XI and XO is recommended 2MΩ (7.3.2.3 External Crystal),
It is 1 M on the sample circuit of the data sheet. (Figure 10, Reference Design 1) which is better, 1M or 2M?
④ In the sample circuit (8.2.2.2 Downstream Ports Implementation)
It is not pulled up on the USB communication line, but is there no need for pulling up?
best regards
