Timeline of standalone gigabit copper PHYs

The following shows a timeline for gigabit PHYs from 1999 until today. Missing are Realtek and Attansic.

I updated the doc to show the trends on a per-port basis for cost and power. While the PHYs have different MAC interfaces, and some press releases quoted in 10K and others in 1K quantity, you can see the general trend toward lower cost and lower power due to Moore’s Law (and competition).
