Description

The ML2021CP is a monolithic analog line equalizer designed for telephone applications. It features a switched capacitor filter that provides a range of frequency response curves optimized for telephone line equalization, while minimizing group delay.

Specifications and 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 of 6 mA typical from ±5V supplies

- TTL / CMOS compatible interface

- Double buffered data latch

- Selectable master clock of 1.544 or 1.536 MHz

- Synchronous or asynchronous data loading capability

- Compatible with ML2003 and ML2004 logarithmic gain/attenuator

Application Scenarios

The ML2021CP is commonly used in telephone systems for line equalization. It can be used to adjust the slope, height, and bandwidth of the signal, optimize group delays, and provide anti-alias filtering. It is compatible with other ML series components such as the ML2003 and ML2004.
