IXF18103
10 Gigabit Ethernet LAN or WAN PHY
product brief
Product Overview
The Intel
IXF18103 is a highly integrated
solution for 10GbE Local Area Network (LAN)
and Wide Area Network (WAN) port applications
compliant as per IEEE802.3ae specifica-
tions. The IXF18103 supports 10GbE LAN
(10.3125Gbps) and WAN (9.953Gbps)
applications.
The 10 Gigabit MAC (per IEEE 802.3ae)
handles frame encapsulation, verification,
10GbE flow control, and Remote Monitor-
ing/Simple Network Management Protocol
(RMON/ SNMP) statistics management. The
IXF18103 also handles the 802.3ae Physical
Coding Sub-layer (PCS) and WAN Interface
Sub-layer (WIS) functions of the 10 Gigabit
Ethernet standard. The PCS hardware han-
dles the 64B/66B encoding/decoding to
provide the transition density and balance of
the 10.3125Gbps stream. The WAN Interface
Sub-layer provides the rate matching mecha-
nism for 9.953Gbps rate transport, as well as
the STS-192c/STM 64c framing structure
used in WAN PHY applications.
The system interface supports the industry-
standard System Parallel Interface Level 4
(SPI-4) Phase 2. This interface is 16 bits wide
with 622Mbps800Mbps Double Data Rate
(DDR) clocking. The SPI-4 Phase 2 interface
is Low Voltage Differential Signaling (LVDS),
which produces fewer connection concerns
than previous 64-bit High-Speed Transport
Layer (HSTL) interfaces.
On the line side, the IXF18103 supports
the IEEE 802.3ae XSBI interfaces. The 16 bit
LVDS interface can operate at 622Mbps to
support the 10GbE WAN rate of 9.953Gbps,
and at 644Mbps to support the 10GbE LAN
rate of 10.3125Gbps.
The IXF18103 also supports an integrated
Pseudo Random Bit Sequence (PRBS) packet
generator/analyzer for the PCS and WIS
blocks per IEEE 802.3ae clause 49 and 50.
Line remote, line local, system remote, and
system local loop backs are also supported,
as well as Synchronous Payload Envelope
(SPE) payload test loop back for general
development functionality test and debug.

Benefits
s
Device is optimized to support low cost and low
power requirements of 10GbE LAN and WAN
s
The XSBI interface comprised of 16-bit LVDS I/O runs
at 622Mbps for 10GbE WAN and at 644Mbps for
10GbE LAN
s
This accommodates both WAN and LAN rates in a
single module
s
Helps minimize pin count and allows interface archi-
tecture to be scaled beyond 10Gbps
s
LVDS I/O, which improves signal integrity versus HSTL
implementation
s
It is independent of the type of data protocol being
transferred
s
Highly integrated 10GbE solution
s
Enables flexible Line Card configurations for 10GbE
LAN or WAN PHY
s
Provides flexible loss less flow control which is very
important in asynchronous network applications

All these devices are pin-, footprint-, and register set-compatible. This allows customers to design one line card for multiple
applications, providing cost savings over a single line card with other unsupported features.
The IXF18103 is designed to provide a single chip solution for all 10GbE LAN or WAN Physical Layer and MAC requirements
for metro and core networks, and offers the following features and benefits:
