... Operating modes 4.2.1 Power down When this mode is selected the SLIC is switched off and the TIP and RING pins are in high impedance. The line detectors are also disabled therefore the off-hook condition cannot be detected. The power down mode can be selected in emergency condition when it is necessary to cut any current delivered to the line ...

... Active DC characteristics & supervision When this mode is selected the STLC3075 provides both DC feeding and AC transmission. The STLC3075 feeds the line with a constant current fixed by RLIM ( range). The on-hook voltage is typically 40 V allowing on-hook transmission; the self generated Vbat is -50 V typical. If the loop resistance is very high and the line current cannot reach the programmed constant current feed value, the STLC3075 behaves like voltage source with a series impedance equal to the protection resistors 2xRp (typ. 2x50 Ω ...

... ZAC impedance ● Transmit and receive: The AC signal present on the 2W port (TIP and RING pins) is transferred to the Tx output with -12 dB gain and from the Rx input to the 2W port with gain ● wires conversion: The balance impedance can be real or complex, the proper ...

... The circuit showed in the “Application diagram” is related to the simple first order filter. Once the shaped and filtered signal is obtained at RTTX buffer output it is injected on the TIP/RING pins with gain or +12 dB gain. It should be noted that this is the nominal condition obtained in presence of ideal TTX echo cancellation (obtained via proper setting of RTTX and CTTX) ...

... This simple network has a double effect: ● it synthesizes a low output impedance at the TIP/RING pins at the TTX frequency ● it cuts the eventual TTX echo that would have been transferred from the line to the TX output 4.2.4 Ringing When this mode is selected, the STLC3075 self generates a higher negative battery (-70 V typ ...
