EXAMPLE ARCHITECTURE

The figure below shows a multi-service

switching platform using QuadPHY-II

devices for backplane interconnect and

client signal physical interfaces.

As a serial backplane transceiver, the

redundant high-speed links simplify the

interface to a working and protect fabric.

The 10GE line cards use the QuadPHY-

II as a PHY supporting XAUI on the line

side and mating to a 10GE MAC using

XGMII.

Infiniband and Fibre Channel line cards

applications are also shown. The half-

rate mode of the QuadPHY-II enables 1

and 2 Gbit/s support using the same

device.

The other applications shown are a XAUI

retimer and an XGMII extender where

the MAC and Optics module separated

by longer distance.
