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.

... Test Active State ( Proper operation of the Test Active State requires the previous state be the Forward Active state to determine the on hook or off hook status of the line. In this state, the SLIC can perform two different tests. If the subscriber is on hook when the state is entered, a loopback test is performed by switching an internal 600Ω ...

... Most of the SLICs in the UniSLIC14 family feature 2-Wire loopback testing. This loopback function is only activated when the subscriber is on hook and the logic command to the SLIC is in the Test Active State. (Note: if the subscriber is off hook and in the Test Active State, the function performed is the Line Voltage Measurement.) During the 2-wire loopback test, a 2kΩ ...

... Power Sharing Power sharing is a method of redistributing the power away from the SLIC in short loop applications. The total system power is the same, but the die temperature of the SLIC is much lower. Power sharing becomes important if the application has a single battery supply (-48V on hook requirements for faxes and modems) and the possibility of high loop currents (reference Figure 25) ...

Page 26

... Battery Selection L Battery selection is a technique, for a two battery supply system, where the SLIC automatically diverts the loop current to the most appropriate supply for a given loop length. This results in significant power savings and lowers the total power consumption on short loops. This technique is particularly useful if most of the lines are short, and the on hook condition requires a -48V battery ...
