AMD Introduces New Ringing Slic for Zero-Loop (ZL) Applications
AMD Introduces New Ringing Slic for Zero-Loop (ZL) Applications
AUSTIN, TX -- May 5, 1997 --AMD today announced a new Subscriber Line Interface Circuit (SLIC) for zero-loop applications, such as Integrated Services Digital Network (ISDN) terminal adapters, home network boundary routers, and set-top applications. The AMD Ringing SLIC-ZL™ device is the newest addition to AMD's SLIC family, enabling AMD to offer a full range of highly integrated ICs for zero-, short-, and long-loop applications.
The Ringing SLIC-ZL device is ideal for designs that need to support Plain Old Telephone Service (POTS) with lower performance capabilities relative to the very short loops inherent in terminal designs. The device meets the demands of the terminal adapter market for low-power dissipation, efficient ringing, small overall board space requirements, and ease of use. The Ringing SLIC-ZL device supports on-chip ringing, on-hook transmission, on-chip battery switching, programmable current feed, and optional on-chip polarity reversal available with the Ringing SLIC-ZL-1JC device.
"The Ringing SLIC-ZL device puts AMD in a leadership position in the burgeoning zero-loop market," said Mike Wodopian, marketing director for AMD's Communication Products Division. "Our SLICs provide the basis for the lowest-cost, system-level solutions in the industry because our aggressive integration and economical package design minimize linecard board space requirements and reduce production costs."
The Ringing SLIC-ZL device extends a comprehensive product offering from AMD that includes the previously announced Am79R79 Ringing SLIC and the Am7946 Digital Loop Carrier (DLC) SLIC. The Am79R79 is designed for short-loop applications such as hybrid fiber coax, Fiber In The Loop (FITL), Wireless Local Loop (WLL), Personal Communications Services (PCS), and video telephony. The Am7946 is designed to meet long-loop requirements, from low-level POTS systems to highly integrated special service linecards. AMD SLIC devices pair with the SLAC™ family of codec/filters to support battery feed, overvoltage protection, ringing, supervision, coding, hybrid, and test (BORSCHT) functions.
The Ringing SLIC-ZL device (part number Am79R70) and the Ringing SLIC-ZL-1JC device (part number Am79R70-1JC) are available in various package options and performance grades.
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 Ethernet infrastructures, Integrated Services Digital Network (ISDN) solutions, and cordless telephone applications compliant with the CT2 and DECT standards.
