Hello Xiaowei,

The TXB0104-Q1 can support up to 20MHz (when operating VCCA = 1.8V and VCCB = 3.3V). However, I would recommend going with AXC4T774 instead.

TXB supports auto-sensing which limits the output current drive. If you plan to use longer traces, then AXC would be the way to go.

Regards,

Josh
