Dual-mode 40G and quad-channel 10G backplane
PHY solution from NetLogic
NetLogic Microsystems, Inc. has introduced the NLP3342,
a dual-mode quad-port 10GBase-KR and 40GBase-KR4 backplane
PHY with Energy Efficient Ethernet (EEE). NLP3342 is designed
using 40nm CMOS process and is targeted at transmission
of 10Gbps and 40Gbps signals over standard backplanes, and
is compliant with the IEEE 802.3az Energy Efficient Ethernet
standard. The NLP3342 PHY device also integrates NetLogic'
electronic dispersion compensation (EDC), 3-tap transmit
pre-emphasis, automatic receive link margin calibration
and forward error correction (FEC) technologies.
NetLogic Microsystems' NLP3342 PHY is suggested for data
centers and telecommunications equipment. This enables data
center and infrastructure network managers . The NLP3342
PHY device enables customers to develop a wide range of
equipment such as blade servers, ATCA switches and routers,
with backplanes that can support multiple form factors and
"As blade servers and networking equipment enable
high computational processing in the data center and infrastructure
networks, the need for high-speed connectivity that can
scale from 10Gbps to 40Gbps becomes an important element
of these chassis-based systems," said Jag Bolaria,
senior analyst at The Linley Group. "NetLogic Microsystems
continues to drive market-leading innovations by now offering
an Energy Efficient Ethernet compliant feature in a quad-port
10GE PHY that in turn allows network owners to deploy green
data center and infrastructure networks."
"The NLP3342 builds upon six generations of field-proven
and market-leading 10GE PHY technology at NetLogic Microsystems,"
said Stefanos Sidiropoulos, vice president of Physical Layer
Products at NetLogic Microsystems. "Delivering the
industry's first dual-mode 40G and quad-channel 10G backplane
PHY solution that integrates Energy Efficient Ethernet enables
our customers to develop highly robust and scalable backplanes
that meet stringent energy-efficient requirements for high-density
NetLogic Microsystems' new NLP3342 supports 10Gbps transmission
for XFI-to-KR as well as 40Gbps transmission for XLAUI/XLPPI-to-KR4
modes over standard backplanes. The device consumes 550mW
per channel and offers low-power modes with the EEE feature.
In addition, the NLP3342 PHY supports Clause 73 auto-negotiation
and link training, Clause 74 Forward Error Correction (FEC)
and KX / KX4 bypass modes.
