Re: [BP] proposed channel model change



rich,

   As indicated by the table below, i saw very little problem with ripple.
The peak magnitude of ripple in the 1000BASE-KX range was < 0.4dB.

                              charles

  IEEE802.3ap channels run through proposed channel spec for 1000BASE-KX

Case #7/Case7 FM 13SI 1 T D13SI L6.s4p     0.327  -0.18dB   0.057dB

Proposed spec:  Mcc < 1.0, Bcc: no spec but smaller is better,
max |ILD|:  1.0dB at DC going to 1.625dB at F2.
