ML2021 - Telephone Line Equalizer

Datasheet Summary

Description

The ML2021 is a monolithic analog line equalizer for telephone applications.

The ML2021 consists of a switched capacitor filter that realizes a family of frequency response curves optimized for telephone line equalization while minimizing group delay.

Features

  • Slope, height, and bandwidth adjustable Optimized group delays (500 Hz to 6.4 kHz) On chip anti-alias filter Bypass mode Low supply current 6 mA typical from ±5V supplies TTL / CMOS compatible interface Double buffered data latch Selectable master clock 1.544 or 1.536 MHz Synchronous or asynchronous data loading capability Compatible with ML2003 and ML2004 logarithmic gain/attenuator General Descr.
