CORDLESS UNIVERSAL TELEPHONE INTERFACE

The MC34016 is a telephone line interface meant for use in cordless telephone base stations for CT0, CT1, CT2 and DECT. The circuit forms the

SEMICONDUCTOR

interface towards the telephone line and performs all speech and line

TECHNICAL DATA

interface functions like dc and ac line termination, 2–4 wire conversion, automatic gain control and hookswitch control. Adjustment of transmission parameters is accomplished by two 8–bit registers accessible via the integrated serial bus interface and by external components.
