DS90UB964-Q1: MAP tool

Hi Thomas,

Please help answer the following questions:
1. What is the function of strobe position?
2. What is the EQ gain corresponding to each level of EQ?
3. What is the corresponding relationship between SP and EQ?

Hi Lucy,

These questions would be best answered within the attached application note.

snla301 - Margin Analysis Program (MAP) and strobe positions for UB954 and UB960.pdf

Please let me know if there's any further details I can provide.

Best,

Thomas

Hi Thomas,

I know there are two stages of EQ, but what is the difference between EQ1 and EQ2?
The documentation doesn't describe what the gain is for each EQ stage?

Hi Lucy,

The FPD RX EQ is set during adaptation to a state where there are not errors on the link. EQ1 and EQ2 both contain 8 EQ levels, for the full 16 levels available on this device

Best,

Thomas

Hi Thomas,

I understand what you mean, but I still have some unanswered questions, which are as follows:
1. What is the difference between EQ1 and EQ2?
2. What the gain is for each EQ stage?

Hi Lucy,

The EQ1 and EQ2 stages work together to create the 15 stages of EQ in the FPD RX. Unfortunately, we cannot share the details on EQ gain for each stage.

Best,

Thomas
