Part Number: DS125BR401A
DS125BR401A Datasheet Table 6: A-Channel Equalizer Settings, shows N/A for this pin. Apparently it is no longer used? This is confusing. Why wasn't it labelled a no connect like Pin 23?
Plus the reference design schematic (sheet 12 in DS125BR401AEVM UG) shows a DS125BR800, not a DS125BR401A. Again, confusing. Comparing the DS125BR401A pinout to the DS125BR800 pinout, I think I have this figured out, but is there a schematic that shows the DS125BR401A and not the DS125BR800?
On the DS125BR401A pin 19 is not used. All the equalization settings for the A-side inputs are controlled with EQA0 (pin 20).
The evaluation board was designed to accept either device. The schematic connections to all the DS125BR800 or DS125BR401A pins should be identical.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
