AMD Introduces Ringing SLIC and Digital Loop Carrier SLIC.AUSTIN, Texas--(BUSINESS WIRE)--Dec. 4, 1995--Advanced Micro Devices today announced two new Subscriber Line Interface Circuits (SLIC SLIC Subscriber Line Interface Circuit SLIC Scottish Library and Information Council SLIC System Licensed Internal Code SLIC Subscriber Line Interface Card SLIC Session Layer Interface Card (Alacritech, Inc. ) for telephone applications. The Am79R79 Ringing SLIC offers through-chip ringing for short-loop applications. The Am7946 Digital Loop Carrier In telephone communications, a technology that increases the number of channels in the local loop by converting analog signals to digital and multiplexing them back to the end office. (DLC) SLIC is designed for long-loop capability. Short-loop applications, such as hybrid fiber coax (networking) Hybrid Fiber Coax - (HFC) A kind of physical connection used in networks for audio, video, and data. DVB (Digital Video Broadcast) is used in Europe and DOCSIS is used in N America. , Fiber In The Loop (FITL FITL Fiber-In-The-Loop (telecommunications) FITL Flight Increment Training Load ), Radio In The Loop (RITL RITL Radio-In-The-Loop (telecommunications) ), Personal Communications Services See PCS. (PCS), set top boxes and video telephony are ideal environments for the Am79R79 device. This highly integrated IC features a programmable, constant current design with a battery-switching function to manage power distribution between short-loop and long-loop/ringing functions. The switching component allows a designer to take advantage of lower short-loop power requirements, conserving battery power while operating in short-loop mode. The Am7946 DLC SLIC is designed to meet long-loop requirements, from low-level Plain Old Telephone Service (POTS) systems to highly integrated special service linecards. Battery operating voltage is -40 V to -58 V with a low standby power feature. Programmable features include constant current feed, overhead and loop-detect threshold for the flexibility to handle both metering and non-metering applications. Other features of the Am7946 DLC include scaled line voltage output, internal voltage regulation, on-chip thermal management (TMG) and a polarity reversal option. A tip open state for ground start lines is included, along with a ground key detector. Power is routed by three on-chip relay drivers, each protected from voltage spikes by a corresponding snubber circuit (32-PLCC only). AMD (Advanced Micro Devices, Inc., Sunnyvale, CA, www.amd.com) A major manufacturer of semiconductor devices including x86-compatible CPUs, embedded processors, flash memories, programmable logic devices and networking chips. SLIC devices pair with the SLAC family of codec filter devices to support battery feed, overvoltage protection, ringing, supervision, coding, hybrid and test (BORSCHT) functions. Aggressive integration and economical package design minimizes linecard board space requirements for reduced production costs. The Am79R79 and Am7946 are available in various package options and performance grades. The Am79R79-3 Ringing SLIC in a 32-pin PLCC package is priced at $5.95 per unit in quantities of 10,000. The Am7946-3 Digital Loop Carrier SLIC in a 32-pin PLCC package is priced at $5.65 per unit in quantities of 10,000. Extensive product literature, evaluation boards, software packages and design kits are available to help designers quickly and easily evaluate AMD SLIC/SLAC device features and performance. In addition to offering silicon solutions for the public infrastructure market, AMD provides a wide range of communications products for use in private LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. Ethernet infrastructures, Integrated Services Digital Network Integrated services digital network (ISDN) A generic term referring to the integration of communications services transported over digital facilities such as wire pairs, coaxial cables, optical fibers, microwave radio, and satellites. (ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. ) solutions, and cordless telephone applications compliant with CT2 and DECT standards.
