Programmable system chips take Sonet
onboard
Lucent Technologies is using the ORSO82G5 and ORSO42G5 field programmable system chips in its next generation CBX 3500 multiservice edge switch.
Lucent Technologies has selected the ORSO82G5 and ORSO42G5 field programmable system chips (FPSCs), as well as the ispGDX2 generic digital crosspoint switch, for use in its next generation CBX 3500 multiservice edge switch The CBX 3500 switch has been specifically created to allow service providers to offer more profitable frame relay, asynchronous transfer mode (ATM) and private line services, and to have the ability to deploy new Ethernet and IP/MPLS services

Big, fast and wide PLDs in full production
Lattice Semiconductor has announced the completion of the production release of its second-generation SuperFAST BFW (Big-Fast-Wide) family, the ispLSI 2000VE family.
Analogue front end is dynamically reconfigurable
Lattice Semiconductor has added a new member to its ispPAC programmable analogue device family.
The Lattice devices are used within the system interconnect scheme for board-to-board communications.
The signal integrity characteristics and the embedded Sonet digital logic in the 2.7Gbit/s serdes devices allow Lucent to drive high bandwidth signals over long distances throughout the entire system.
Additionally, the highly integrated ORSO system chips provided native Sonet capability without the need for additional soft cores or external PLLs.

"The Lattice FPSCs pioneered the approach of putting ASIC embedded cores and FPGA gates on the same silicon die", said Stan Kopec, Lattice Vice President of Corporate Marketing.
"In contrast to ASICs with embedded FPGA gates, FPSCs have a broad range of uses".
"The embedded cores hold industry-standard intellectual property, including bus interface, high-speed line interface and high-speed transceiver cores".
"When these embedded cores are combined with programmable gates, they can be used by customers in a variety of advanced system designs, such as Lucent's CBX 3500 multiservice edge switch".
Intended for high-speed serial Sonet backplane data transmission, the ORSO82G5 includes eight backplane transceiver channels, each operating at up to a 2.7Gbit/s datarate, providing a full-duplex synchronous interface with built-in clock/data recovery (CDR) and more than 400K usable FPGA system gates.
The ORSO42G5 includes four backplane transceiver channels, each operating at up to a 2.7Gbit/s datarate, along with more than 10K LUTs of FPGA logic.
Both devices provide a full 10Gbit/s backplane data connection with protection between a line card/redundant line card and switch fabric/redundant switch fabric.
The FPGA portion can be used to implement a 2.5 or 10Gbit/s Sonet-based switch fabric interface.
Both the ORSO82G5 and ORSO42G5 provide a serdes-based high-speed interface for inter-device communication on a board or across a backplane.
The devices also support Sonet data scrambling and descrambling, streamlined Sonet framing, transport overhead handling, cell insertion and extraction, and idle cell insertion/deletion, plus programmable logic to terminate the network into proprietary systems.
All Sonet functionality is hidden from the user and no prior networking knowledge is required.
The ispGDX2 family includes devices with up to 16 high-speed (800Mbit/s) serdes, up to four 360MHz sysClock PLLs, sysI/O interface capability and are available in 64, 128 and 256 I/Os.
With blazing fast 3.0ns input-to-output speeds and versatile sysIO buffers, the ispGDX2 family supports the most demanding interface and interconnect needs of next-generation system designs.
