Hi,

I would like to confirm if LSF0108 support the speed of 30MHz? How to choose the pull-up resistor for this application?

Thanks.

Hi Di Wang,

It supports 30Mhz operation.

You could refer to the FAQ about the LSF operation here below:
e2e.ti.com/.../742100

You could also consider using the SN74AXC8T245 for 1.8 to 3.3V operation which supports up to 190Mhz.
