accessrunner ? controller-less adsl modem device set for pci applications 2 conexant doc. no. 100394b proprietary information october 19, 1999 adsl (asymmetric digital subscriber line) is a transmission technology used to carry user data over a single twisted pair line from the central office to the customer premises. the downstream (central office to customer premises) direction typically supports a much higher data rate than the upstream or return (customer premises to central office) channel. this asymmetric nature lends itself to applications like remote lan access, internet access, and video delivery. the downstream data rates can go up to 8 mbps. the upstream data rates can go up to 1 mbps. actual data rates depend on the transceiver implementation, loop length, impairments, and transmitted power. the conexant adsl modem device set for pci applications is based upon a scalable architecture. this architecture will enable the device set to support an emerging set of adsl specifications called g.lite. g.lite is expected to make it possible for telcos to deploy consumer-oriented, ?always on? 1.5 mbps internet access services without the need for splitter equipment or wiring changes at the customer premises. d20441 line driver features ? differential input and output line driver ? thermal shutdown capability ? line impedance matching during power- down ? fixed differential gain 11627 adsl dmt data pump features ? low power (0.5w) consumption ? dsp-based programmable adsl data pump ? no external interleave ram, 16 kbytes built-in ? single 3.3v 5% power supply ? echo cancellation ? digital interface and rate buffering ? adsl framing ? forward error correction (fec) encoding and decoding and interleaving ? constellation encoding/decoding ? ifft modulation and fft demodulation ? transmit and receive signal digital filtering ? time domain equalization ? frequency domain equalization ? clock recovery ? crc and scrambling ? digital interface framing ? atm mode ? bit-synchronous mode ordering information product package device number accessrunner p46 pci bus interface 176-pin tqfp p46 accessrunner 11627 adsl discrete multitone (dmt) data pump 176-pin tqfp 11627 accessrunner 20431 analog front end 32-pin tqfp 20431 16-pin ssop 20441-12 accessrunner 20441 line driver 32-pin tqfp 20441-11 revision history revision date comments a 07/09/99 initial release b 10/19/99 defined dash numbers and updated figures for 20441 line driver, changed document number from dsl- 015, a information provided by conexant systems, inc. is believed to be accurate and reliable. however, no responsibility is assumed b y conexant for its use, nor any infringement of patents or other rights of third parties which may result from its use. no license is granted by implication or otherwise under any patent rights of conexant other than for circuitry embodied in conexant products. conexant reserves the right to change circuitry at any time wi thout notice. this document is subject to change without notice. conexant products are not designed or intended for use in life support appliances, devices, or systems where malfunction of a c onexant product can reasonably be expected to result in personal injury or death. conexant customers using or selling conexant products for use in such applicati ons do so at their own risk and agree to fully indemnify conexant for any damages resulting from such improper use or sale. conexant, ?what's next in communications technologies?, accessrunner, lanfinity, and the conexant logo, are trademarks of conexant systems, inc. product names or services listed in this publication are for identification purposes only, and may be trademarks or registered trademarks of their respective companies. all other marks mentioned herein are the property of their respective owners. ?1999, conexant systems, inc. all rights reserved
