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.
