Manufacturer:ST Description:Internal tone modulation. The ENT (tone enable) terminal activates the internal tone signal, modulating the dc output with a 650-mV peak-to-peak trapezoidal waveform. The internal oscillator is factory trimmed to provide a tone of 22-kHz. No further adjustment is required. Burst coding of the tone can be accom- plished, due to the fast response of the ENT input and rapid tone response. This allows implementation of the DiSEqC™ protocols. |
