the BCM96012 eliminates the need for storing bulky reels of telephony grade cable in space-constrained lab environments. accurate loop modeling and filter design has ensured a very close match between telephony grade 24 awg cable and the BCM96012. the BCM96012 may be used in conjunction with adsl line emulators to extend the reach beyond the 18,000 feet maximum, or may be used in conjunction with real cable to provide a simple way of adjusting the loop total reach. when used with broadcom vdsl development systems, the BCM96012 provides a complete, end-to- end vdsl test and development platform.

BCM96012 overview the BCM96012 is a cascaded series of passive elements designed to emulate the channel response of 24 awg telephony twisted-pair wires. designed as a series of slope equalizer sections, the frequency response of the BCM96012 closely matches the actual response of twisted-pair wires. it has a broad frequency response and can be used for adsl, vdsl or fttc systems where data rates can exceed 50 mbps. the BCM96012 is supplied with an emi shield to protect against spurious noise ingress. the sectioned nature of the design enables loop reach to be modified easily. bridged taps may also be inserted at various points to evaluate link performance. 1,000 feet 3,000 feet 9,000 feet 15,000 feet channel responses for a selection of the BCM96012 sections are shown above. phone: 949-450-8700 fax: 949-450-8710 email: info@broadcom.com web: www.broadcom.com broadcom , the pulse logo and connecting everything tm are trademarks of broadcom corporation and/or its subsidiaries in the united states and certain other countries. all other trademarks are the property of their respective owners. broadcom corporation 16215 alton parkway, p.o. box 57013 irvine, california 92619-7013 ? 2002 by broadcom corporation. all rights reserved. 96012-pb06-r-6.20.02
