Low Power Universal SLIC Family
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 toeliminate anyleakage paths as foundin our competition’s JI process. This makes the UniSLIC14 family compliant with “hot plug” requirements and operation in harsh outdoor environments.
