MB86626 - KetWave AFE ADSL Analog Front End

General Description

The analog circuitry consists of two 15-bit DACs with associated anti-imaging filters, two 15-bit ADCs with anti-aliasing filters and two programmable gain summing amplifiers (PGA).

A clock multiplier and bandgap reference are incorporated on-chip.

Key Features

  • Integrates all active circuits except transmit line driver.
  • Programmable for G. dmt (1 channel) or G. lite (2 channel).
  • Low power, 3.3V operation - from 235mW/ch (2 channel CO G. lite) to 525mW (RT G. dmt).
  • Integrated filters and 15-bit A/D & D/A converters.
  • 0 to +38 dB AGC range for receive channel.
  • Supports analog and digital echo cancellation.
  • Excellent SFDR and input noise.
  • 0.35µm CMOS technology with Triple Well.

Product Flyer Mixed Signal Division MB86626 KeyWave™AFE ADSL Analog Front End 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.
