ADL5205 Maximum input voltage swing

I'm looking to use the ADL5205 Dual digital VGA but am confused by the rated input swing in the datasheet.

 

In Table 1 Page 3 it shows "Maximum input swing: 8 Vp-p" in the input stage section

In Table 3 Page 6 "Absolute Maximum Ratings" it says:

-"Input Voltage (VINx+, VINX-): -0.5V to +3.1V"

-"Differential Input Voltage((VINX+)-(VINX-)): +/- 1V"

 

So how can the input swing be 8 Vp-p with an absolute maximum differential voltage of +/- 1V?

Is there a mistake in the datasheet or am I misunderstanding this?

 

Thank you

 

Tom
