Differential Integrated Crosstalk Noise (ICN) Mitigation in the Pin Field Area of SerDes Channel


The integrated crosstalk noise (ICN) has been widely used as an alternative to the insertion crosstalk ratio (ICR) for channel crosstalk evaluation in the IEEE 802.3ba standard. In this work, the differential ICN mitigation scheme by using idea of orthogonality is implemented in two adjacent differential pairs first. In the full pin map area of SerDes channel, new pin map patterns based on such scheme are prosed and compared with the conventional pan map patterns. The new pin maps mitigate the differential ICN drastically, yet maintain the G:S ratio. A preliminary study is conducted on fan-out trace routing to maintain the benefit from new pin map patterns.
