TUSB4020BI: Drive level SPEC of TUSB4020BI

Hi,

TUSB4020BI will drive the crystal for 1.8V clock or accept 1.8V oscillator clock on XI. Is there a specific spec you are looking for here?  Please refer to section 9.1.1 Crystal Requirements of the TUSB4020BI datasheet for more details on Crystal requirements. You may also find the below E2E post useful as well.

Sir:

The crystal drive level is defined in the crystal we used So the TUSB4020BI does not care about this SPEC, right?

Hi,

As long as the crystal can be driven for a 1.8V clock then everything should be okay.
