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 transmission speeds.
"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 systems."
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.
