Hi

They are using CY7C65632, but it seems that the eye pattern opening on the DS port is narrower. Is ther any method to adjust the Eye pattern? or Tool?

Best Regards

Hi,

HX2VL doesn't have a feature to config parameters such as pre-emphasis.

Do kindly check schematic, component, and layout design whether it meets AN72332.

Hi takayama san

Just in case, Is it okay to understand that even with Blaster Plus, this eye pattern can not be adjusted?

Hi Arai-san,

In case of using HX3 Blaster Plus (not Blaster), they can change pre-emphasis depth and amplitude for each DS port.

But, as you know, HX3 Blaster Plus cannot use for HX2VL.
