Low Power UniSLIC14 Family
The UniSLIC14 is a family of Ultra Low Power SLICs. 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.
