TUSB8042A: What is the input voltage VIL(max) and VIh(min) of XI?

Part Number: TUSB8042A

The maximum ratings of the XI are given in the data sheet. (see below)
What is the input voltage VIL(max) and VIh(min) of the XI?
I am currently considering connecting an oscillator with a 1.8 V output.
The output provisions are as follows.
Vol(max): 0.182 V
Voh(min): 0.160V

    When connected directly to a crystal, the signal at the XI pin is an analog sine wave.

    Those VOL/VOH values are specified for a certain output current, so the actual output voltage range with a high-impedance CMOS input will be wider. Anyway, the 1.8 V square wave will be fine.
