Hi team,
We have a combination with DS90UB953 and 1 meter cable(RG174), and we run the maptool (ub962_margin_analysis.py).
The result is meet the recommands margin of 3 EQ levels with 4 passing strobe positions, but streaming still have some error frame occur.
Then we change 15 meter cable and the streaming looks better. So we find out that AEQ floor default setting(0x02) maybe not lower enough for 1 meter cable.
I'm confused about AEQ_STATUS Register (Address 0xD3) & AEQ_CTL2 Register (Address 0xD2) description when I try to configure these registers.
- There is a part "The setting for the AEQ after adaption can be read back from the AEQ_STATUS register 0xD3". Is that meaning the adaptive EQ status is a current value by AEQ algorithm? Is it a dynamic value?
- What the different between EQ_STATUS_1 & EQ_STATUS_2?
- Does setting lower AEQ floor will causing any side effect when using 15 meter cable?
- When should the ADAPTIVE_EQ _RELOCK_TIME be set? How does it improve or what should I be concerned about?
Best regards
Dennis Tseng.
