Line-Card-On-A-Chip Handles Telecom And Datacom

The M29311/312 line-card-on-a-chip (LoC) family is a complete physical-layer solution for high-bandwidth ATM and IP DS3/E3 services in applications such as wireless uplinks, routers and digital-loop carrier equipment. The devices include two independent DS2/E3 electrical line interface units (LIUs) with built-in jitter attenuators, and two DS3/E3 framers. An automatic build-out feature allows for interfacing over 1,800' of cable. Independent system interfaces support cell and packet termination into an industry-standard system bus of UTOPIA Level 2 for ATM, and POS-PHY Level 2 packets and /or SPI-3 for ATM cells and HDLC packets. Each channel can be independently configured to operate at DS3/E3 rates, supporting different protocols. Each can also be turned off and tri-stated for redundancy support and power conservation. The devices are supplied in 19 mm PBGA packages. Pricing for 1-port M29311 is $34 each and for the 2-port M29312 is $55 each in OEM quantities. MINDSPEED TECHNOLOGIES INC., Newport Beach, CA.
