Part Number: TUSB9261

Customers have a question about the TI solution (TUSB9261PVP) of USB3 to SATA.

(1) What is the power sequence timing between "3.3V up" and "Global power reset "GRSTz" (Pin4) up"?

(2) Can I use firmware to delay "Global power reset "GRSTz" (Pin4) up time? Thanks a lot.

Hi,

Please refer to section 7.3.1.4 Power-Up and Reset Sequence in the TUSB9261 datasheet. GRSTz timing can be varied and has a minimum timing of 2 ms after power supplies are stable.
