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.
