Framer puts 10Gbit Ethernet over Sonet
Cypress Semiconductor is sampling a single-chip framer that makes it possible to extend 10 Gigabit Ethernet (10 GbE) LANs over standard Sonet/SDH networks.
Cypress Semiconductor is sampling a single-chip framer that makes it possible to extend 10 Gigabit Ethernet (10 GbE) LANs over standard Sonet/SDH networks Supporting 10 GbE WAN PHY, 10 GbE LAN PHY, OC-192c/STM-64 and direct mode, the POSIC10G reduces network and linecard complexity while enabling carriers to offer cost competitive 10 GbE services over MAN/WAN networks

Nonvolatile SRAMs expand to 8Mbit
New 2 and 8Mbit nvSRAMs feature access times as low as 20ns, infinite read, write and recall cycles, and 20-year data retention.
Design tool bridges high and low levels
Integrated design environment includes both code-free and high-level-language programming modes in one package.
POSIC10G follows closely on the heels of Cypress's sampling of POSIC2GVC, its full-featured OC-48/STM-16 framer with virtual concatenation.
Operating in four modes, POSIC10G enables edge and core router designers to use the same design for multiple cards in their system, considerably simplifying linecard design.
POSIC10G is a true single-chip 10 GbE solution that integrates a 10 GbE media access controller (MAC), a Sonet/SDH framer, a physical coding sublayer (PCS), and a WAN interface sublayer (WIS).

Rosie remotes use robust Cypress wireless technology to overcome limitations of infra-red, including line of sight requirements and range of less than 10m.
Laser navigation sensor takes MCU onboard
SoC combines Cypress's patented OptiCheck technology with a programmable CPU, USB interface and a highly configurable power management unit.
The device efficiently handles 10 GbE packets, supporting jumbo frames and address filtering.
POSIC10G supports SPI 4.2, the industry standard for network processor interface on 10Gbit/s linecards.
The chip provides advanced support for Sonet's automatic protection service (APS), having two on-chip Sonet/SDH framer blocks.
The APS switching/recovery is both manual and automatic, enabling flexible redundancy options for customer networks.
"The next logical step to move up in data rates is to enable 10 Gigabit Ethernet applications to extend corporate LANs to the MAN or WAN level", said Christopher Norris, vice president of Cypress's data communications division.
"POSIC10G solves a number of technical and business issues at the same time.
Using our chip, carriers can offer 10 GbE as a backbone technology over previously dark fiber using the same DWDM equipment deployed in the MAN".
Enterprises can now connect their LANs to Sonet/SDH-based access equipment.
They can achieve high performance with a simpler network architecture, eliminating the need for protocol conversion, since the traffic remains IP/Ethernet based.
This arrangement ensures cost-effective bandwidth for the LAN from switch to switch, efficiently aggregating 10 GbE over Sonet/SDH.
POSIC10G is the only framer in the market today to enable enterprises to extend their 10 GbE network range to 20km.
Enhanced packet buffer memory helps prevent packet drop due to network congestion.
"Cypress' POSIC10G framer IC is an important step enabling the use of 10 GbE in the metro", said Allan Armstrong, Director of Optical Transport Semiconductors at RHK, a leading telecommunications industry analyst firm.
"The WAN PHY mode allows 10 GbE to be transported up to 20km over legacy Sonet equipment, and the four modes of operation allow system vendors to minimise engineering expense by developing a single line card for multiple applications".
Samples of POSIC10G (CY7C9547-FAC) are available now in a 624-pin BGA.
Pricing starts at $600 in quantities of 1000.
