Le79R79 Overview
The Le79R79 Ringing SLIC device is a bipolar monolithic SLIC that offers on-chip ringing. Designers can achieve significant cost reductions at the system level for short-loop applications by integrating the ringing function on chip. Examples of such applications would be ISDN terminal adaptors, fiber-in-theloop, radio-in-the-loop, hybrid fiber/coax and video telephony (home-side) boxes.
