I have two questions about TUSB1310A power rails:

1. Do JTAG signals belong to VDD1P8 power rail? And how should pull up/down the signals, if I use level shifter?

2. Which signals belong to VDDA3P3?

Hello Frank,

1. Yes, JTAG signals are 1.8V.

2. The only terminal connected to the 3.3V rail are: P12, P13, P14.

Regards.

Thanks for your quick reply.

So if I use an oscillator as the input clock, should I supply 1.8V to it?

Thanks,

Correct, 1.8V.
