interfaces
through the consolidation of the
(PHY) transceiver designed for use
receiver and transmitter PHY
in 10 Gbps applications. Its XFI-

compliant serial interconnect
with the integration of encode/
supports interfacing with XFP
decode/alignment logic, FIFOs,
modules at 10 Gigabit Ethernet
integrated clock drivers, multiple
or 10 Gigabit Fibre Channel data
loopback features and PRBS
rates. Its flexible system side
generation, and verification for
interconnect supports interfacing
both the line side and the system
with MACs and ASICs using a
side. This combination reduces
the number of components and
XAUI interface.
enables 10 Gbps Ethernet and
Fibre Channel systems to
dissipate much less power.
The TLK10021 device makes use
of CMOS technology to offer an
advanced combination of high-
