Low Power Universal SLIC 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.
