ILF3866N

ILF3866N Interface Circuit of Subscriber Line ILF3866N (Interface Circuit) (Functional Analogue – TFF3866 by Company Megaxess) Microcircuit ILF3866N is essentially the subsriber's line interface (SLIC). Microcircuit ILF3866N is intended for matching the signals of the subsriber's telephone line and the internal tract of the analogue or analogue-digital automatic telephone station (АТS). Microcircuit is used in the automatic telephone station. In the analogue-digital automatic telephone stations the microcircuit ILF3866N is used in the kit with the codek microcircuit IL145567N (IL145567DW), IL145557DW. Functional features of the microcircuit: - provides power supply to the subscriber's line and the phone set (Phone); - performs receipt and transfer of the signals in two directions, as well as separation of signals between the double-wire and quadruple wire station lines; - ensures matching of impedances; - determines the state of stub (receiver is on hook /receiver is off hook); - controls application of the call signal (via the external relay); - performs the line testing by the leakage current to the ground; - performs the line protection from short circuit (heat protection); - has the digital port for the commands receipt from the microcontroller; - temperature range is from minus 40 to plus 70 С. Application of the microcircuit ILF3866N will make it possible to reduce power consumption, dimensions and cost of the telephone station, enhance quality and reliability of the ph...
