Aimed at developers of next-generation SONET/SDH communication equipment, the Titan 19244 single-chip framer and pointer processor is capable of handling data at 40Gbps in both upstream and downstream directions, as well as supporting pointer processing up to STS-1 granularity.

"This is the first time a standard products manufacturer has delivered silicon for an emerging line rate (40Gbps) prior to OEMs developing costly ASICs," said Christian Scherp, Infineon Techologies North America VP of marketing for optical networking.

"Not only is Titan the first merchant OC-768 framer, but Infineon has also included a quad OC-192 mode of operation," said Allan Armstrong, director of optical transport semiconductors at RHK. "System manufacturers building DWDM equipment can leverage their investment by using the same framer in both OC-768 and quad OC-192 line cards," he added.

The single-chip device is available in a quad-port STS-192/STM-64 version or a single STS-768/STM-256 SONET/SDH framer and pointer processor device. It is capable of pointer processing at STS-1 granularity for all four ports, and extends support to any legal mix of flexible concatenation levels such as STS-2c, STS-3c, STS-4c, STS-192c.

The chip also supports termination and generation of TOH bytes, TOH add and drop ports, as well as monitoring of selected POH bytes such as B3. Both the line and system side interfaces are compliant with the OIF SFI-4 standard, making the Titan 19244 capable of interfacing with industry-standard SFI-4 OC-192 transponders.

The Titan 19244 provides four 16-bit LVDS, SFI-4 compliant parallel buses operating at 622Mbps both on the line and system sides.

Fabricated using 0.15?m technology, the Titan 19244 is housed in a 1,413-pin FCBGA package and is priced at $1,850 in volume quantities.
