LMH5401: Amplifier maximum input withstandability for 50Ohm single ended input matching

Part Number: LMH5401

As per the datasheet recommendation we are planning to use Supply voltage (VS) as 5V (VS+ = 2.5 V, VS– = –2.5 V).

we are planning to use amplifier LMH5401 as ADC driver and single ended 50-Ohm input to 200Ohm differential output.

For maximum Input voltage range at (VS & VS+) is mentioned as (VS–) – 0.7  and  (VS+) + 0.7. So we can take it as VS+ = 3.3 V, VS– = –3.3 V as absolute maximum input levels.

Now we have assumed our input is 50Ohm matched (single ended) and for maximum of +/3.3V (6.6Vp-p) if we calculate for 50 Ohm load the input power will be +20.4dBm.

Can we take +20.4dBm as absolute maximum RF input power when we use Supply voltage (VS) as 5V (VS+ = 2.5 V, VS– = –2.5 V)? Is it our above calculations are correct?
