Loop.

• Power Management/Shutdown

The UniSLIC14 family achieves its ultra low power operation

• Battery Tracking Anti Clipping

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.

• Single 5V Supply with 3V Compatible Logic

• Zero Crossing Ring Control

- Zero Voltage On/Zero Current Off

• Tip/Ring Disconnect

• Pulse Metering Capability

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.
