Title: need help regarding Txline parameters Post by akki on Apr 17th, 2008, 11:14am hi all, I am simulating a CML buffer with 50 ohm Tx line in spectre, I am unable to understand one thing why two parameters are given there TD and PL , i think both relate some way or other to length of Tx line. when i simulate the ckt with no PL i am getting good result but when it is disastrous with any non zero value of PL. MY QUESTIONS ARE. 1. HOW TD AND PL ARE RELATED . 2. WHAT MIN LENGTH OF TX LINE SHOULD I CONSIDER ,FOR A DATA AT 10 gBPS 3. FROM WERE CAN I GET THE VALUE OF RESISTANCE AND CONDUCTANCE TO MODEL LOSSY TX LINE. kindly help... -akki |
