TL16C550D: The setting of XI pin and XO pin in case of using oscillator

Part Number: TL16C550D

Hi all

Would you mind if we ask TL16C550D?

Our customer will use TL16C550D with oscillator, so we would like to confirm the setting of XI pin and XO pin in case of using oscillator.

<Question1>
At first, is it possible to use oscillator for XI input?

<Question2>
XI : oscillator input
The level of VIH and VIL depend on VCC(power), right?
And then, if you have some specification for oscillator clocks, could you share us?
Duty Cycle : 40%(min), 60(max)?
Frequency Tolerance : ±XXppm?
Rise / Fall Time : XXns??

<Question3> 
XO should be open, right?

Kind regards,

Hirotaka Matsumoto
