Note that parts marked with either the "Am" or the "Le" part number prefix are equivalent devices in terms of form, fit, and prefix appearing on the topside mark is the only difference. Due to size constraints, QFN devices are marked by omitting the “Le” prefix and the performance grade dash character. For example, Le79R79-1FQC is marked 79R791FQC.

For delivery using a tape and reel packing system, add a "T" suffix to the OPN Ordering Part Number when placing an order. 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.

Le79R79 Data Sheet Zarlink Semiconductor Inc. Le79R79 Data Sheet PRODUCT DESCRIPTION The Zarlink family of subscriber line interface circuit SLIC products provide the telephone interface functions required throughout the worldwide market. Zarlink SLIC devices address all major telephony markets including central office CO , private branch exchange PBX , digital loop carrier DLC , fiber-in-the-loop FITL , radio-in-the-loop RITL , hybrid fiber coax HFC , and video telephony applications. The Zarlink SLIC devices provide the two- to four-wire hybrid function, DC-loop feed, and two-wire supervision. Two-wire termination is programmed by a scaled impedance network. Transhybrid balance can be achieved with an external balance circuit or simply programmed using a companion Zarlink codec/filter, such as the Le58QL0xx Quad SLAC QLSLAC device. The Le79R79 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, fiber-in-the-loop, radio-in-the-loop, hybrid fiber/coax and video telephony homeside boxes. The Le79R79 Ringing SLIC can provide sufficient voltage to meet the stringent LSSGR five-ringer equivalent specification. Using a CMOS-compatible input waveform and wave shaping R-C network, the Le79R79 Ringing SLIC can provide trapezoidal wave ringing to meet various design requirements. In order to further enhance the suitability of this device in short-loop, distributed switching applications, Zarlink has maximized power savings by incorporating battery switching on chip. The Le79R79 Ringing SLIC device switches between two battery supplies such that in the off-hook active state, a low battery is used to save power. In order to meet the Open Circuit voltage requirements of fax machines and maintenance termination units MTU , the SLIC device automatically switches to a higher voltage in the On-hook Standby state.
