"Crystal Inputs" SPECIFICATION of video decoder devices.

Hello,

 

I have a question of "Crystal Inputs" specification of video decoder devices.

In the datasheets of video decoder devices (ADV7182A, ADV7182, ADV728xA, ADV728x, ADV7180 etc.) says the spec as follows on the SPECIFICATIONS (ELECTRICAL CHARACTERISTICS):


 "Crystal Inputs"  VIH min = 1.2 V, VIL max = 0.4 V

 

Is this spec applied only when we use oscillator?
(Isn't this spec applied when we use crystal?)
or
Is this spec applied when we use crystal?

 

Thank you!
Best regards.
Tamu
