1 / 29 page  L3000S L3030 June 1997 SUBSCRIBER LINE INTERFACE KIT PRELI MINARY DAT A . PROGRAMMABLE DC FEEDING RESIS-TAN- CE AND LIMITINGCURRENT (fourvalues avai- lable) . THREE OPERATING MODES : STAND-BY, CONVERSATION, RINGING . NORMAL/BOOSTBATTERY, DIRECT/REVER- SE POLARITY . SIGNALLING FUNCTION (off-hook/GND-key) . FILTERED OFF-HOOK DETECTION IN STAND-BY (10ms) . QUICK OFF-HOOK DETECTION IN CONVER- SATION (< 1ms) FOR LOW DIAL PULSE DE- TECTION DISTORTION . HYBRID FUNCTION . RINGING GENERATION WITH QUASI ZERO OUTPUT IMPEDANCE, ZERO CROSSING IN- JECTION (no ext. relay needed) AND RING TRIP DETECTION . AUTOMATIC RINGING STOP WHEN OFF- HOOK IS DETECTED . PARALLEL AND SERIAL DIGITAL INTERFA- CES . TELETAXE SIGNALINJECTION (2VRMS/5VRMS) . LOW NUMBER OF EXTERNAL COMPO- NENTS . GOOD REJECTION OF THE NOISE ON BAT- TERY VOLTAGE (20dB at 10Hz and 35dB at 1kHz) . POSSIBILITY TO WORK ALSO WITH HIGH COMMON MODE CURRENTS . INTEGRATED THERMAL PROTECTION WITH THERMAL OVERLOAD INDICATION . SURFACE MOUNT PACKAGE (PLCC44 + PowerSO-20) DESCRIPTION PLCC44 FLEXIWATT15 The ST SLIC KIT (L3000S/L3030) is a set of solid state devices designed to integrate main of the fun- ctions needed to interface a telephone line. It con- sists of 2 integrated devices : the L3000S line interface circuit and the L3030 control unit. This kit performs the main features of the BORSHT functions : - Battery feed - Ringing - Signalling - Hybrid Additional functions, such as battery reversal, extra batteryuse, line overvoltagesensing and metering- pulse injection are also featured ; most external characteristics,as AC and DC impedances,are pro- grammable with external components.The SLIC in- jects ringing in balanced mode and for that, as well as for the operation in battery boosted, a positive battery voltage shall be available on the subscriber card. As the right ringing signal amplification both in voltage and in current is provided by SLIC, the ring signal generatorshall only provide a low level signal (0.285Vrms). This kit is fabricated using a 140V Bipolar technolo- gy for L3000S and a 12V Bipolar I 2L technologyfor L3030. L3030 is available PLCC44 and L3000S in both FLEXIWATT15 and PowerSO-20 for surfacemount application. This kit is suitable for all the following applications: C.O. (CentralOffice),DLC (Digital LoopCarrier) and high range PABX (Private Automatic Branch Ex- change). PowerSO20 slug-up slug-down ORDERING NUMBERS : L3030 (PLCC44) L3000SX-VM (FLEXIWATT15) L3000SX (PowerSO20 slug-up) L3000SX-77 (PowerSO20 slug-down) 1/29 |
