STLC3065 General Description

The STLC3065 is a SLIC device specifically designed for WLL (Wireless Local Loop) application.One of the distinctive characteristics of this device is the ability to operate with a single supply voltage (from +5.5V to +15.8V) and self generate the negative battery by means of an on chip DC/DC converter controller that drives an external MOSswitch.

The self generated battery voltage tracks the line resistance. In this way the power dissipation inside the device is low enough to allow the use of smallSMD package (TQFP44).

Other useful characteristics for application in the WLL environment are the integrated ringing generator and the dual two wire port that allows to drive two different terminal equipment whether the transmission is voice or data. When one port is transmitting the other one is idle.

The control interface is a parallel type with open drain output and 3.3V logic levels.

The metering pulses are generated on chip starting from two logic signals (0, 3.3V) one defines the metering pulse frequency and the other the metering pulse duration. An on chip circuit then provides the proper shaping and filtering.

Metering pulse amplitude and shaping (rising and decay time) can be programmedby externalcomponents.A dedicated cancellation circuit avoid possible CODEC input saturation due to Metering pulse echo.

Constant current feed can be set from 20mA to 40mA.Off-hook detection threshold is programmable from 5mA to 9mA.

The device, developed in BCD100II technology (100V process), operates in the extended temperature range and integrates a thermal protection that set the device in power down when Tj exceeds 140°C.
