Fujitsu Microelectronics Introduces Two SERDES Framer Interface Macros for System-on-Chip ASICs in Advanced Networking Applications

OIF-compliant cores provide pre-verified building blocks for efficient application design

San Jose, CA, June 4, 2002 — Adding to its large portfolio of macros and IPs for high-end network development, Fujitsu Microelectronics America, Inc. (FMA) today introduced SERDES Framer Interface SFI-5 and SFI-4 macros for system-on-chip (SOC) ASICs in gigabit and terabit routers, optical cross connect switches and Dense Wave Division Multiplexing (DWDM) optical transmission systems.

Both new macros, which comply with Optical Internetworking Framework (OIF) standards, are available as core library cells. System-level designs based on these new cores let designers architect their ASICs with verified interoperability, which simplifies interface design and can reduce total time to market significantly. Their introduction to the market continues Fujitsu's program of providing cores and macros that provide clocking, data transfer, standard interfacing and connectivity at the highest speed rates for long haul, metro, access and storage applications.

"These industry-standard, high-performance I/O macros combine with Fujitsu's leading edge process technology and packaging to streamline and simplify the system-design process, significantly reducing time-to-market for our customers," said Keith Horn, FMA's vice president of marketing.

SFI-5 Targeted for Long Haul Designs
The SFI-5 OIF compliant transceiver macro is a 17-channel physical I/O interface to be used in high bandwidth ASICs and offers aggregate of 50Gbit/second in each direction. The macro includes 17-channel (1:16 SERDES) transmitter and receiver arrays, along with a bias unit. It integrates a dynamic deskew function at the receiver and 50-ohm termination resistors for both receiver and transmitter. It requires very low power consumption, operates at supply voltages of 1.2V and 2.5V, and is fabricated using Fujitsu's advanced 0.11-micron CMOS process technology. Target applications include long-haul optical and metro area transport systems, as well as wavelength division multiplex equipment and line cards for routers and switchers.

SFI-4 Designed for Metro Area Network Applications
The new SFI-4 macro enables the interconnection of physical layer (PHY) and link layer devices at an aggregate rate of 10 to 12.5Gbit/second in each direction. The macro incorporates a total of 16-data lines plus one clock for both transmit and receive directions. Fujitsu has demultiplexed the internal pathway to 64 bits, so the macro can be easily integrated with backend logic. The SFI-4 macro also incorporates on-chip termination resistors on the transmitter and the receiver.

The SFI-4 is built using Fujitsu's 0.18-micron standard CMOS technology with triple well isolation, and operates on 1.8V and 3.3V power supplies. Under the worst-case conditions, 0.92W are required for the transmitter macro, with 0.43W required for the receiver macro.

Fujitsu is supporting the SFI-4 and SFI-5 macros with front-end simulation models, timing analysis and place/route models, and floorplanning (Library Exchange Format) tools.

"We continue to expand Fujitsu's macro library to include all the advanced IPs required for comprehensive next-generation system-on-chip ASIC development," said Yuk Yung, FMA's director of high-performance ASIC marketing. "Fujitsu is currently working with customers on several 10G and 40G designs utilizing SFI 4 and 5 macros. We plan to continue providing industry-standard high-speed links such as XAUI and proprietary high-speed clock data recovery macros to the networking market."
