MOTOROLA ANALOG IC DEVICE DATA
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
interface towards the telephone line and performs all speech and line
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.
