The feature set and mon pinouts of the Uni SLIC14 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 Uni SLIC14 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. - Ultra Low Active Power (OHT) < 60m W - Single/Dual Battery Operation - Automatic Silent Battery Selection - Power Management/Shutdown - Battery Tracking Anti Clipping - Single 5V Supply with 3V patible Logic - Zero Crossing Ring Control - Zero Voltage On/Zero Current Off - Tip/Ring Disconnect - Pulse Metering Capability - 4 Wire Loopback The Uni SLIC14 family has many user programmable Features . This family of SLICs delivers a low noise, low ponent 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 Uni SLIC14 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 petition’s JI process. This makes the Uni SLIC14 family pliant with “hot plug” requirements and operation in harsh outdoor environments.
