VANCOUVER, B.C. -- PMC-Sierra Inc. here today announced a physical layer/framer device that it said is the first complete all-CMOS mixed-signal solution for OC-48c (2.5 gigabits per second) applications.
The single chip S/UNI-2488 integrates the digital framer and processor functions together with complete analog physical layer(PHY) frontend clock and data recovery, clock synthesis and serializer/deserializer (Serdes) functions. The low-power device provides world-class jitter performance, including jitter transfer compliance.
The S/UNI-2488 device also provides for a high-speed serial-to-serial and serial-to-parallel dual-mode operation, which enables mass deployment of high-speed routers, multi-service switches, and optical cross-connect equipment.
Implemented in 0.18-micron/1.8-volt CMOS technology, the S/UNI-2488 physical layer/framer achieves a typical power consumption of under 3 watts. CMOS technology lowers power requirements and eases future silicon integration for next-generation OC-48 equipment upgrades.
The S/UNI-2488's analog serial backplane port allows for optical cross-connect applications and/or automatic protection switching (APS) line-card redundancy where packet or cell termination is not required. Previously, individual DWDM lambdas were only able to provision a single user service. With its analog serial backplane port, the S/UNI-2488 connects seamlessly to the PM5372 TSE device providing for bit-synchronous STS-1 optical cross connect grooming. Now each individual DWDM lambda can be fully provisioned to carry multiple user services, greatly enhancing carrier service deployment.
The S/UNI-2488 in serial-to-parallel digital framer mode acts as the second device introduced in PMC-Sierra's Packet-over-Sonet/SDH Level 3 (POS-PHY Level 3) family (see April 25 story). "The recent Chess OC-48 chip set and today's S/UNI-2488 OC-48c product announcements, along with last quarter's acquisition of AANetcom are further advances in PMC-Sierra's strategy to enable optical carrier-class service provisioning equipment optimized for DWDM and Sonet/SDH transport technologies" said Steve Perna, vice president and general manager of PMC-Sierra's Optical Networking Division.
The S/UNI-2488 is packaged in a 31-by-3-mm 416 UBGA package, representing the smallest footprint available. It is priced at $269 in 1,000-unit volume quantities, with samples available in July.
