... PD) OWER DOWN MODE PIN To reduce consumption during dialling or register recall (flash), the TEA1098 is provided with a power-down input (PD). When the voltage on pin PD is LOW, the current consumption from V and V is reduced to typically BB DD 460 A. Therefore a capacitor of 470 sufficient to power the TEA1098 during pulse dialling or flash ...

... B: 0.7 dB/ms NOISE ENVELOPE B: 0.7 dB/ms C: 0.07 dB/ms Decision logic: pins IDT and SWT The TEA1098 selects its mode of operation (Tx Idle) by comparing the signal and noise envelopes of both channels. This is executed by the decision logic. The resulting voltage on pin SWT is the input to the voice switch. To facilitate the distinction between signal and noise, the signal is considered as speech when its envelope is more than 4 ...
