Single-chip LAN PHY runs up to 40km

A new 10 Gigabit Ethernet LAN PHY enables geographically dispersed enterprise backbones and data centres to send 10 GbE directly over optical fibre up to 40km.

Cypress Semiconductor is sampling a 10 Gigabit Ethernet LAN PHY that enables inter-campus and intra-campus, geographically dispersed enterprise backbones and data centres to send 10 GbE directly over optical fibre up to 40km.

The POSIC10GLAN enables the longest round-trip connection of any LAN PHY on the market (20km under worst-case network conditions).

This enables enterprises to progress to 10 GbE fibre networks, from existing lower bandwidth ATM and GbE backbones.

POSIC10GLAN's large buffers enable efficient network flow control, maintaining data integrity with no packet loss under increasing network congestion.

POSIC10GLAN supports industry-standard interfaces with 10 GbE 16bit interface (XSBI) on the line side and system packet interface (SPI-4.2) on the system side.

"The need for low-cost, high-bandwidth enterprise backbones will drive 10 GbE deployment", said Gahan Richardson, senior product marketing manager of Cypress's Data Communications Division.

"Reliability is key to 10 GbE over fiber.

POSIC10GLAN, with its large buffers and efficient flow control, enables flexible network architectures with guaranteed zero packet loss".

"Cypress's POSIC10GLAN provides a big boost to 10 GbE in the enterprise", said Christopher Norris, Vice President of Cypress's Data Communications Division.

"It enables companies to easily extend their Ethernet networks across widely dispersed campuses.

It provides enterprise backbone connectivity at high bandwidth and low cost".

Samples of POSIC10GLAN (CY7C9548-FAC) are available now in 624-pin BGAs.

Prices range from $240 per 1000 units to $155 in volume.
