Part Number: LMH0002
Other Parts Discussed in Thread: LMH1218

Hi Team,

My customer wants to use LMH0002 with supporting MADI.
Can he also apply the following 6-dB passive attenuator block?

Hi Yaita-San,

Yes this should work.

Please note 10pF Cap was used to slow slew rate on LMH1218 device. This Cap value may need to be tuned for the LMH002 device.

Hi Nasser-san,

Thank you always for your kind support.
I understand.

In addition, I believe adding 75ohm termination is ideal in terms of load symmetry.
What do you think of it?

Hi Yaita-San,

Agreed. This makes impedance load balanced.
