App note: PCB design for 10/100 switches and PHY

PCB_design_10_100_sw_phy

Design guide on PCB layout from Micrel on 10/100 switches and PHY

This application note is intended to assist customers in
designing products that comply with both EMI and ESD
standards using Micrel’s 10/100 family of Ethernet
products.
The printed circuit board (PCB) is the single most
important factor that affects EMI, ESD and overall
performance. In order to meet these requirements depend
on good design practices. The goal here is to minimize
digital and common mode noise as well as to provide
shielding between the PCB’s internal circuitry and the
external environment. These PCB design practices should
apply to the entire PCB design, not just to Micrel Ethernet
products.
