DS30EA101 LOS pin behavior

Other Parts Discussed in Thread: DS30EA101

Please advise me the DS30EA101 LOS pin behavior.

According to the data sheet of the device, LOS pin goes to High when
There is no input.

However, when I checked LOS pin on EVK, it stayed Low when the input cable was off.

I suspect that this devices may be configure to equalize any amplitude input.
Consequently, LOS mat not be set to High regardless of no input.
Can you please check it referring design.
