DS280DF810: Pin outs

Part Number: DS280DF810

Hi Experts,

Good day.

For DS280DF810, page 6, is N in name refer to active low for pin "READ_EN_N" like this pin"ALL_DONE_N " for this datasheet pins have thereshold are RXnp.RXnN only? Or there are others pin which On-Chip Eye Opening Monitor (EOM) reflect on it?

https://www.ti.com/lit/ds/symlink/ds280df810.pdf#page=6

Also, signal type for test pins, can user use as input or not?

Thank you.

Regards,
Archie A.

    See responses below.

      • Table 1 on the datasheet (PIn functions) has the pin details you are asking for. READ_EN_N function depends on EN_SMB
    • Or there are others pin which On-Chip Eye Opening Monitor (EOM) reflect on it?
      • The INT_N pin (interrupt pin) can be configured to become asserted when retimer input eye opening values do not meet some threshold value. Refer to INT_N details in the datasheet (see "Interrupt Signals" sub-section)
    • Also, signal type for test pins, can user use as input or not?
      • The TEST pins definition is on datasheet table as well. They are inputs and voltage logic is LVCMOS. These pins are reserved; you should be tying them to ground or leaving them floating

    Thanks,
