The LAN8700/LAN8700I and LAN8187/LAN8187I are higly-integrated devices designed for 10*100Mbps Ethernet systems. they are based on IEEE 10BAZE-T and 100BAZE-TX standards. The IEEE 802.3-2005 standard for 100BAZE-TX defines networking over two pairs of Category 5 unshielded twisted pair table or Type 1 shielded twisted pair table.
This document provides a practical guideline for incorporating the Philips Peripheral Component Interconnect (PCI) Express Physical (PHY) IC layout into a Printed Circuit Board (PCB) design. This document is composed of two main sections:
Section 2 provides guidelines for PCI Express lane connection for the PCB traces, vias and AC coupling capacitors, as well as add-in card edge finger considerations.
Section 3 describes the layout and termination of PXPIPE, which is Philips’ proposed interface between the PHY and the Media Access Control (MAC).
