PHY device tolerates Metro-Ethernet conditions

The S19253 complements AMCC's QT2025 LAN/WAN PHY with EDC by operating in a -40 to +85C industrial temperature environment, critical for Metro-Ethernet and Carrier Ethernet applications.

Applied Micro Circuits has released a PHY device that is pin-to-pin compatible with the recently released Pemaquid S19258.

The S19263 is a XAUI-to-XFI 10G LAN/WAN PHY industrial temperature device for 10GbE, 10G Fibre Channel and WIS (OC-192/STM-64) network applications.

The S19263 represents AMCC's second device in its MEtrON (Metro Ethernet Optical Networks) product family.

It is a highly integrated XAUI to XFI physical layer integrated circuit for Ethernet and Fibre Channel LAN and WAN applications based on SFP+ or XFP optical modules.

The S19253 complements AMCC's QT2025 LAN/WAN PHY with EDC by providing a solution that supports operation in a -40 to +85C industrial temperature environment, critical for Metro-Ethernet and Carrier Ethernet applications.

It is also fully compliant to IEEE802.3-205 and XFP4.5 standards.

"Unlike climate-controlled locations such as customer premises and data centres, industrial-grade components designed for LAN and WAN applications must meet telco-grade standards in order to ensure high reliability in extreme temperature environments", said Michael Howard, Principal Analyst and Co-Founder at Infonetics Research.

"The AMCC design team ensured that the S19263 meets these industrial temperature requirements, while making the device pin-compatible with the recently released Pemaquid S19258 framer/mapper/PHY".

"As the convergence of Ethernet and Sonet-based networks continue to accelerate, our customers have been requesting a 10GbE LAN/WAN PHY that can meet their needs of a Metro-Ethernet and Carrier Grade Ethernet system and can function reliably in extreme temperature conditions", said Neal Neslusan, Director of Transport Marketing at AMCC.

"The S19263 clearly meets this requirement and is the latest example of why AMCC is becoming the supplier of choice for the 10 Gigabit Ethernet transport market".

The S19263 supports 10GBASE-SR/LR/ER and 10GBASE-SW/LW/EW fibre optic PMDs.

It supports XFP modules and single-mode fibre SFP+ modules and is forward compatible with AMCC's Pemaquid S19258 10G Framer/Mapper/PHY device with built in G.709 GFEC and EFEC.

The S19263's mechanical and ball map configuration, as well as its register maps, are forward compatible with the Pemaquid S19258.

As a result, the S19263 provides an easy migration path from XAUI to XFI 10G LAN/WAN to XAUI to XFI LAN/WAN/OTU-2 applications using XFP and SFP+ optical modules.

With an integrated FRACn synthesiser, it requires only one-low cost external reference oscillator to support 10G line rates from 9.954Gbit/s up to 10.52Gbit/s, while meeting SONET/SDH jitter requirements.

In addition to this timing flexibility, the S19263 device features WIS framing and 10GbE LAN pass-thru modes.
