The feature set and common pinouts of the UniSLIC14 family positions it as a universal solution for: Plain Old Telephone Service (POTS), PBX, Central Office, Loop Carrier, Fiber in the Loop, ISDN-TA and NT1+, Pairgain and Wireless Local Loop. The UniSLIC14 family achieves its ultra low power operation through: Its automatic single and dual battery selection (based on line length) and battery tracking anti clipping to ensure the maximum loop coverage on the lowest battery voltage. This architecture is ideal for power critical applications such as ISDN NT1+, Pairgain and Wireless local loop products. The UniSLIC14 family has many user programmable features. This family of SLICs delivers a low noise, low component count solution for Central Ofﬁce and Loop Carrier universal voice grade designs. The product family integrates advanced pulse metering, test and signaling capabilities, and zero crossing ring control. The UniSLIC14 family is designed in the Intersil “Latch” free Bonded Wafer process. This process dielectrically isolates the active circuitry to eliminate any leakage paths as found in our competition’s JI process. This makes the UniSLIC14 family compliant with “hot plug” requirements and operation in harsh outdoor environments.
