Problem with LVDS via HSMC on Cyclone III Development Kit

--- Quote Start ---

I am using a TI ADC Daughter Card with a Cyclone III Development Kit. I connected the ADC Card via HSMC. There are 2 channels with 6 LVDS DDR input pins.

Which Cyclone III kit specifically?

I just looked at the schematic for one of the Cyclone III kits, c3_f780_host.pdf, and on page 15 there are HSMC 100-ohm terminations for each of the LVDS receiver signals.

Have you installed those terminations?

Cheers,

Dave
