--New family of semiconductor solutions designed to help lower the cost of provisioning and servicing subscriber lines--
ATLANTA, GA -- June 8, 1998 --AMD today announced a new family of semiconductor products for the telecommunications infrastructure industry. AMD's AQSLAC™ /HVASLIC™ advanced linecard chipset is the first in a family of new generation semiconductors designed to help telecommunications infrastructure OEMs offer feature-rich products which lower both the initial cost of provisioning and the long-term cost of servicing a subscriber line. The AQSLAC™/HVASLIC™ chipset implements a four-channel universal telephone line interface, eliminating the need for external hardware, such as test and ring relays, by integrating test, monitoring and ringing functions. The new products add to AMD's industry-leading portfolio of Subscriber Line Interface Circuits (SLICs) and Subscriber Line Audio Processing Circuits.
"The AQSLAC™/HVASLIC™ chipset represents the next generation of telecommunication semiconductors," said Homer Lloyd, marketing director of AMD's Communication Products Division. "AMD has sold millions of SLIC and SLAC semiconductors, and we understand that equipment provisioning is only one part of the total cost equation. By integrating more system level functions, AMD's AQSLAC™/HVASLIC™ chipset can help OEMs offer equipment to telecommunications service providers that is cost-effective at provisioning and delivers ongoing savings throughout the equipment's service life."
In addition to reducing the cost per line by integrating many functions that would otherwise require external hardware, this chipset provides a complete software configurable solution to all transmission parameters, DC feed variables, metering and DTMF generation and extensive loop supervision capability, including off-hook, ring-trip and ground-key detection.
The AQSLAC™ (Am79Q224x) is a low voltage CMOS device that provides A/D and D/A conversion, filtering, equalization, hybrid balance, companding, supervision, ringing and test functions, and the interfaces to an external microprocessor and the digital back plane. One AQSLAC™ can drive up to four HVASLIC™ devices, controlling power consumption and providing signaling.
The HVASLIC™ (Am79R2xx) is a high voltage bipolar device that drives a single subscriber line, maintains its longitudinal balance and senses the conditions on that line. The HVASLIC™ is optimized for use exclusively with the AQSLAC™ device as part of a multiple-line card. Used together, the HVASLIC™ and the AQSLAC™ create a powerful, cost-effective solution for OEMs and their customers.
The advanced linecard chipsets family will help ensure AMD remains the world's foremost merchant supplier of integrated circuits for telephone linecards. "Our leadership in telecommunications began in 1979 when we pioneered DSP-based linecard ICs," said Lloyd. "Over the years, we've sold more than 100 million embedded DSP devices, as well as 50 million SLICs, for telecommunications applications. From low-featured SLICs and nonprogrammable SLAC™ codec/filters to highly integrated, programmable chipset solutions, AMD linecard ICs form the core of the public infrastructure."
Pricing and Availability
The Am79Q224x AQSLAC™ is available in PLCC and TQFP packages. AMD plans to sample the Am79Q224x in August with production planned for the fourth quarter.
The Am79R2xx HVASLIC™ is available in a PLCC package. AMD plans to sample the Am79R2xx in August with production planned for the fourth quarter. Per line pricing (1/4 AQSLAC™ and 1 HVASLIC™) starts at $9.30 in 10K-unit quantities through AMD's distributors.
