Description

The STLC3055N is a SLIC device specifically

designed for wireless local loop (WLL) and ISDN-

terminal adaptors (ISDN-TA) and VoIP

applications. One of the distinctive characteristic

of this device is the ability to operate with a single

supply voltage (from 5.5 V to 12 V) and self

generate the negative battery by means of an

on chip DC/DC converter controller that drives an

external MOS switch.

The battery level is properly adjusted depending

on the operating mode. A useful characteristic for

these applications is the integrated ringing

generator.

The control interface is a parallel type with open

drain output and 3.3 V logic levels.

The metering pulses are generated on chip

starting from two logic signals (0 and 3.3 V) one

define 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 programmed by external

components. A dedicated cancellation circuit

avoid possible codec input saturation due to

metering pulse echo.

Constant current feed can be set from 20 mA to

40 mA. Off-hook detection threshold is

programmable from 5 mA to 9 mA.

The device, developed in BCD III S technology

(90 V process), operates in the extended

temperature range and integrates a thermal

protection that sets the device in power down

when Tj exceeds 140 °C.
