Part Number:DS80PCI810
Dear sir,
Our customer is using DS80PCI810, but they found eye diagram results are different between SMBus slave mode and SMBus master mode (EEPROM).
First, for SMBus slave mode, they set EQ register value = 2D, VOD register value = AF, VOD_DB register value = 00.
The eye diagram result as below:
But using the same setting for SMBus master mode (EEPROM), the eye diagram result as below:
Why they are quite different !?
Attachments are the config file and hex file for EEPROM.

Is there something wrong for EEPROM programming??
Do you have any idea??
Thanks for your help in advance.
