STLC3040FN

The STLC3040FN is one member of the STLC3040 family which is designed as the third generation subscriber line interface which is fabricated in BiCMOS (12V bipolar / 5V CMOS) technology. And this device processes the line current image provided by the L3000N generating the transmit signal and the proper voltage signal that will be sent back to the L3000N in order to synthetize the desired AC/DC impedances on the 2-wire side.

Features of the STLC3040FN are:(1)two chip set + overvoltage protection provide the complete borscht functions;(2)programmable DC feeding resistance and current limiting 0 to 70mA (1.1mA steps);(3)programmable voltage drop according to ttx/on hook transmission needs;(4)integrated ring generator with zero crossing and programmable freq/level;(5)support normal loop start lines, ground start pabx lines, extended loops and pay-phones;(6)reverse polarity hard or soft switching;(7)on hook transmission capability;(8)2 wire impedance synthesis software programmable;(9)hybrid function software programmable;(10)integrated thermal protection with thermal overload indication.

The absolute maximum ratings of the STLC3040FN can be summarized as:(1)negative battery voltage:-80 V;(2)positive battery voltage:+80 V;(3)total battery voltage:140 V;(4)positive supply voltage:+5.5 V;(5)negative supply voltage:-5.5 V;(6)maximum voltage between AGND/BGND:5 V;(7)maximum junction temperature:150 °C;(8)storage temperature:-55 to +150 °C.
