Hi Brian,

this is not for new design, customer already co-layout TUSB211 & TUSB212 on the board, but during qualify TUSB211, they found RSTN spec is not specific show in datasheet. this is for critical OEM customer, need you help to check RSTN spec of TUSB211 for them.

Hi Brian,

TUSB212 also has same description with TUSB211, but the power on and reset timing show in TUSB212 datasheet, TUSB211 doesn't have it. this is key question from customer. that's why they could to check the RSTN spec.
