Transformer Replacement SLIC
linecard designer, know that developing POTS applications today's single-application linecard markets requires balance high-performance cost-effective silicon components. AMD®, world's leading merchant supplier integrated circuits telecommunications, meet your basic line interface needs with Am7920 Transformer Replacement Subscriber Line Interface Circuit. low-cost SLIC alternative traditional transformer-based designs, Am7920 device help develop economical linecard designs cost-sensitive POTS markets developing world areas.
Am7920
Bringing High Technology Low-Cost POTS Linecard Applications
Am7920 SLIC provides basic transformer-like features needed design low-cost, high-performance POTS line interface cards. device gives linecard designers very simple control interface that supports four control states: Active, Ringing, Standby, Disconnect (open circuit). Other basic features AMD's transformer replacement include integrated battery feed, off/on-hook detection, on-hook transmission, on-chip ring trip detector, programmable constant current feed, standby power.
Line TransformerBased Designs
Am7920 SLIC helps simplify design manufacturing POTS line interface cards, making ideal replacement transformer SLICs. With addition surge protection, Am7920 device provides space-saving, economical alternative transformer/ discrete solutions. Manufactured AMD's mature bipolar process technology, compact integrated circuit designed cost-effective, surface-mount applications. transformer approach, however, uses through-hole insertions printed circuit board (PCB), which adds cost complexity manufacturing linecards.
SLIC Save Board Space Costs
Am7920 device available choice 32-pin PLCC 24-pin plastic packages. Both industry-standard packages ensure smaller footprint. Am7920 SLIC only uses less board space, also requires fewer external components than transformer. fact, using Am7920 device lets designers increase number lines board. That means cost common hardware amortized across more channels, resulting lower system costs. adds superior transformer replacement solution-for about same cost transformer. Am7920 SLIC delivers basic functions need develop POTS line interfaces, while allowing reduce design manufacturing costs long run. Samples Am7920 device available now. data sheet, application note, evaluation tools, additional information Am7920 Transformer Replacement SLIC, contact 800-222-9323, visit site http://www.amd.com.
