Part Number: LMK04828

Hi Team,

If customer want to decrease LVDS and LVPECL16 output amplitude, is it possible?
I know "ODL" can increase amplitude a little, but I don't know how to decrease amplitude.
Thank you.

Hi Jabe,

Output swing is not configurable, they can add some sort of resistive network between the LMK's output and the receiver end. Or they can use HSDS output.

Hi Noel,

In my understand, HSDS's swing higher than LVDS even if used HSDS 6mA.
Therefore, HSDS cannot meet customer's request.
Please check it.

Best Regards,

Hi Jade,

If customers need smaller signal strength, use external network to attenuate the signal swing.
