XAUI Agenda 

14th Febuary 2001


0. Current comments to D2.1 

  A- The following points should be discussed and agreed upon as being
  comments to come from the XAUI Jitter Adhoc.

    - Extention of low frequency sinsusoidal jitter mask 
    - Change of RL to -8dB
    - Comment for D2.1 concerning Deterministic Jitter for transmitter
      + This should include comment concerning transmitter with
      equalisation having to comply to receive jitter requirements.

    - CJPAT Pattern for transmit compliance pattern 
      - a note of caution from Ali
      - Pattern should not be too complicated and long as this can
      lead to complication with measurement equipment.
      - Pattern should be such that implementors can use this
      - Mixed Frequency or K28.5 could be sufficient
      - Serial PMD, current using simple scrambler pattern with
      additional influence from A0/A1 bytes for (WAN PHY)

    - High frequency corner frequency should not be raised again as
    issue unless new information concerning this subject is available.
      A- Email to Allan. (Anthony)

    - New low frequency limit and amplitude of group delay
    specification from Compliance Group.
      A- Must be discussed

    - Logistics 
      - Draft out on Friday
      - 2 telco calls befor ballot
      - 2 telco for preparation for plenary

1.1 Break frequencies and amplitudes
  
  A- Find FC white paper on investigation leading to SWAG number of
  0.1UI and 1.5UI for amplitudes. (Allan) This action point shall be
  closed upon studying of the Bell Labs document.

1.2 Very low frequency jitter definition frequency and amplitude

  A- Jitter low corner frequency should be adjusted, comment to be
  entered to D2.1
  A- Amplitude could result from FC White paper

2.5 IEEE Sections, Annex´s and References

  A- An additional Annex shall be written to cover methodology

      A- Termination for measurement of jitter must be defined. We
      could refer to 47.3.3 Driver characteristics, but this currently
      also underspecified.

      A- Receieve Compliance Data Eye

4.4 FEXT/NEXT (Cross Talk)

  A- Crosstalking specifications from typical connectors to be
  collected from connector manufacturers by Rich and Ali.

  A- Theoritical simulation of expected differential crosstalk to be
  done (Anthony)

4.6 Return Loss

  A- Verification of max/min capability of RL required. Distance of
  the first connectors from the driver should be verified for WC. 

  A- Jeff Cain and Tom Grey to try and quantify RL requirements.
    - See section 10. concerning overall verification.

6.4 Defined patterns 

  A- Final acceptance of proposed pattern.

  A- It was requested that Rich could possibly explain how the
  compliance pattern can be generated from MAC.

6.4.1 Compliance Definition

    A- Tom.L to get reflector traffic moving with respect to which
    pattern should be used for compliance.

10. Overall Verification of Jitter Budget

  A- Ongoing simulations for verification of newly proposed jitter
  numbers and patterns are ongoing by
    - Jeff Cain 
    - Tom Gray 
    - IFX 
    - Mysticom
    - Jeff Porter 
    - Dawson
