LMH0002: Can RREF be set to reduce output amplitude to between 300mVpp and 600mVpp SE?

Hi Josh,

I think i understand what spec you are trying to meet. Minimum LMH0002 single ended output swing is 665mV.
1). Perhaps you can have a passive 6dB attenuator. However this means this port would be fixed for 300mV to 600mV output swing. Please take a look at the link below for passive attenuator circuit:
www.radio-electronics.com/.../attenuator-resistor-values.php
Or negative output could have this attenuator while positive is normal configuration. But either of the output should terminated while the other output is used. I am not sure how reflection would effect this low data rate.
2). I have checked LMH0397 and output voltage swing can be changed - through register - to be within 0.5 to 0.6V SE swing.

Thanks Nasser!

This is for an existing board, with 8 SOIC package part -  so I will give the attenuator a try for now.  Does it make sense to install the attenuator after the inductor || 75 ohm resistor, before the AC coupling cap then?
