KeyWave™AFE ADSL Analog Front End

January 2002

Version 1.2

FME/MS/ADSLAFE/FL_1/4282

The Fujitsu MB86626 KeyWave™AFE ADSL Analog Front End

is a complete analog front end for ADSL modems. The device

integrates high resolution analog to digital converters (ADC)

and digital to analog converters (DAC), and combined with

active filtering significantly reduces the requirements placed on

external components. The architecture supports both analog

and digital echo cancellation (EC). The MB86626

KeyWave™AFE is ideal for cost sensitive Remote Terminal

(RT) and power sensitive Central Office (CO) equipment.
