Overview: QCX601 subscriber line interface circuit module (Low Power Ringing SLIC MODULE) uses the modular structure in a single module integrated DC/DC converter bell flow generator, polarity reversal switch, constant current feed circuit, the two / four line conversion circuit of all functions to the system's user interface, the design of small user voice the system is very simple, save the design time of the whole system, users only need to provide +3.3V to +5V DC power supply, constant current feed, ringing, two / four line transformation functions can realize small user voice system is required; at the same time can greatly reduce the volume of the system, reduce the cost.
