TXV0106: skew for Vcca=1.2V and switching char. for Vcca=3.3V

Hans

Part Number: TXV0106

Hello Team, 

the data sheet does not provide the following information:

1. channel to channel skew for Vcca = 1.2V?

2. switching characteristics for Vcca=3.3V and Vccb=1.2V?

May I ask you to provide this missing important information, please?

What is the maximum datarate for below conditions, please:

  • 1,3V LVCMOS -> 3,3V LVCMOS
  • 3,3V LVCMOS -> 1,3V LVCMOS

 Thank you and Best Regards, Hans

    Hi Hans,

    I have further reached out to the team if feasible to include 3.3 V to 1.2 V (for reference, you can expect not > than 1.2 V to 1.2 V).

    However, section 5.6 is the available data as of this time for 1.2 V to 3.3 V, thanks.

    Best Regards,

    Michael.

    Hi Michael, 

    regarding my question #1.: section 5.6 (1.2V to 3.3V) does not provide any channel to channel skew data.

    regarding my question #2.: can you explain your comment "you can expect not > than 1.2 V to 1.2 V", please? How is this related to channel to channel skew?

    Looking at the different switching characteristics I can see that lower Vcca and Vccb makes ch-to-ch skew slower and I can get no idea how it will look like for 1.2V to 1.2V.

    Can TXV0106 be used at 250Mbps for 1.3V LVCMOS -> 3.3V LVCMOS and 3.3V LVCMOS -> 1.3V LVCMOS?

    Thank you and best regards, Hans

    Hi Hans,

    I see, my comment was for tpd switching char.

    Yes, TXV can be used as the worst skew we have seen on bench is for 106 ps with 1.2 V outputs (and this was for a weak corner -40 C, skew was in mid double digits at other temperatures). Note that 1.2 V to 3.3 V worst skew on bench (-40 C) was for 42 ps, thanks.

    Best Regards,

    Michael.

    Hi Michael, this is somehow surprising for me as I expected some ch-ch skew in the mid 100s ps (worse than 330ps) when extrapolating the numbers from the switching characteristics.

    Thanks and best regards, Hans

    Hi Hans,

    Yes, your expectations would be correct if spec'd in the datasheet as this would be for simulation worst case which would be different from bench worst case, thanks.

    Best Regards,

    Michael.
