L3092 Datasheet | STMicroelectronics

DESCRIPTION The SLIC KIT (L3000S/L3092) is a set of solid state devices designed to integrate many of the functions needed to interface a telephone line. It consists of 2 integrated devices ; the L3000S line interface circuit and the L3092 control unit. The kit implements the main features of the BORSHT functions: - Battery feed (balance mode) - Ringing Injection - Signalling Detection December 1997 - Hybrid Function The SLIC KIT injects the ringing signal in balanced mode and requires a positive supply voltage of typically + 72V to be available on the subscriber card. The L3000S/L3092 kit generates the ringing signal internally, avoiding the requirement for expensive external circuitry. A low level 1.5Vrms input is required. (This can be provided by the bo). A special operating mode limits the SLIC KIT power dissipation to 50m W in on-hook condition keeping the on/off hook detection circuit active. Through the Digital Interface it is also possible to set an operating mode that allows measurements of loop resistance and therefore of line lenght. This kit is fabricated using a 140V Bipolar technology for L3000S and a 12V Bipolar I2L technology for L3092. Both devices are available PTH application (FLEXIWATT15 and DIP28) or SMD application (Power SO-20 and PLCC28). This kit is specially suitable to Private Automatic Branch Exchange (PABX) and Low Range C.O. Applications. 1/32 This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice. ..
