Highly Integrated Slic Kit Targeted To Pabx And Key System Applications

The L3234 L3235 is a highly integrated SLIC KIT targeted to PABX and key system applications The kit integrates the majority of functions re- quired to Interface a telephone line. The L3234 L3235implements the main featuresof the broths function: - Battery Feed (BalancedMode) - Ringing Injection - Signalling Detection - Hybrid Function The Kit comprises 2 devices, the L3234 ringing injector fabricated in Bipolar in 140V Technology. Its function is to amplify and inject in balanced mode with zero crossing the ringing signal. The device requires an external positive supply of 100V and a low level sinusoid of approx. 950mVrms. The L3235 Line Feeder is integrated in 60V Bipolar Technology. The L3235 provides battery feed to the line with programmable current limitation. The two to four wire voice frequency signal conversion is implemented by the L3235 and line terminating and balance impedances are externally programmable. The L3234 L3235 kit is designed for low power dissipation. In a short loop condition the extra power is dissipated on an external Transistor The Kit is controlled by five wire parallel bus and Interfaces easily to all first and programmable second generation COMBOS.
