Chapter 4: Backplane Ethernet 10GBASE-KR PHY IP Core 4–33
Dynamic Reconfiguration from 1G to 10GbE
November 2012 Altera CorporationAltera Transceiver PHY IP Core
User Guide
Dynamic Reconfiguration from 1G to 10GbE
Figure 4–7 illustrates the necessary modules to create a design that can dynamically
change between 1G and 10GbE operation on a channel-by-channel basis using the
10GBSE-KR PHY IP Core. In Figure 4–7
Green—Altera- Cores available Quartus II IP Library, including the 1G/10Gb
Ethernet MAC, the Reset Controller, and Transceiver Reconfiguration Controller.
Orange—Logic you must design, including the Arbiter and State Machine. Refer
to Arbitration Logic Requirements and State Machine Requirements for a
description of this logic.
White—1G and 10G settings files that you must generate. Refer to Creating a
10GBASE-KR Design for more information.
Blue—The 1G/10GbE IP core available in the Quartus II IP Library.
