L3030 Datasheet | STMicroelectronics

DESCRIPTION The ST SLIC KIT (L3000S/L3030) is a set of solid state devices designed to integratemain of the functions needed to interface a telephone line. It consists of 2 integrated devices : the L3000S line interface circuit and the L3030 control unit. This kit performs the main features of the BORSHT functions : feed - Battery - Ringing - Signalling - Hybrid June 1997 Additional functions, such as battery reversal, extra batteryuse, line overvoltagesensing and meteringpulse injection are also featured ; most external characteristics,as AC and DC impedances,are programmable with external ponents.The SLIC injects 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 onlyprovide a low level signal (0.285Vrms). This kit is fabricatedusing a 140V Bipolar technology for L3000Sand a 12V Bipolar I2L technologyfor L3030. L3030 is available PLCC44 and L3000S in both FLEXIWATT15 and Power SO-20 for surfacemount application. This kit is suitable for all the following applications: C.O. (Central Office),DLC (Digital Loop Carrier) and high range PABX (Private Automatic Branch Exchange). 1/29 L3000S - L3030 PIN CONNECTIONS (top view) PLCC44 FLEXIWATT15 VBN.C.
