Multichannel LIU and Framer combination devices

28 July 2004 Telecoms, Datacoms, Wireless, IoT

Exar says that it can now offer the industry's first DS3/E3 LIU/Framer/JA combination device family. These devices follow Exar's successful single channel part, the XRT79L71 by adding multichannel integrated parts allowing customers to reduce board space and provides an easy upgrade path from two to four channels on the same board. Targeted applications include access equipment, digital cross-connect systems, routers, 3G base stations and DSLAMs, or virtually any network switch equipment including ATM, WAN, and LAN.

All product family members leverage an integrated ATM UNI/PPP physical layer interface with on-board framers, and LIUs with JA. This family is designed to support ATM direct mapping and cell delineation, as well as PPP mapping and frame processing and clear channel framing. In addition, the devices have Exar's proprietary R3 Technology (reconfigurable, relayless redundancy).

The XRT79L74 (four-channel), XRT79L73 (three-channel) and XRT79L72 (two-channel) share a common 456-PBGA packaging platform and pin-out enabling the designer to support one board design for two, three and four-port applications.
