austriamicrosystems Telephone Line Interface and Speakerphone Circuit AS2522B Key Features - DATA SHEET General Description AS2522 is a CMOS integrated circuit that incorporates DC and AC line adaptation (DC-mask and synthesized ACimpedance of 100 0Ω ) as well as a speech circuit with softclipping, line loss compensation and Rx-volume control for handset and handsfree operation. It shall act as an a/bline powered device, which is controlled by a CPU via a serial interface. Furthermore the AS2522 incorporates a DTMF, FSK transmitter, single tone and ringer tone generator. AS2522 allows to use an off-the-shelf microprocessor without special blocks and functions for telephone applications.
