... Zarlink codec/filter, such as the Le58QL0xx Quad SLAC (QLSLAC™) device. The Le79R70 Ringing SLIC device is a bipolar monolithic SLIC that offers on-chip ringing. Now 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 and set top boxes ...
