Product details

Description

The AS2540 is a CMOS integrated circuit that incorporates a speech circuit (line-adaptation, 2/4-wire conversion, separate Rx- and Tx-amplifiers for handset and modem), MF dialler, ring frequency detector, ring melody generator and a two wire serial interface.

Features

- Line Interface, Speech Circuit, MF Dialler and Tone Ringer on a 28 pin CMOS chip - Programmable via 2-wire serial interface (UART 9600 baud, 8N1) - Watch dog timer for Backup Mode - Additional input for modem transmit path - Additional output for modem receive path - CMOS for high EMC immunity - Low Noise (max.
72 dBm) - Operating range from 15mA to 100mA (down to 5mA with reduced performance) - Soft clipping for handset operation to avoid harsh distortion - Line loss compensation sel.
