BA1604 PLL tone decoder IC

Communication ICs PLL tone decoder IC BA1604 / BA1604F The BA1604 and BA1604F are tone decoder ICs that enable the frequency to be selected in precise detail, using a PLL system. These ICs are configured of a PLL circuit, a detection circuit, a voltage comparator circuit and an output logic drive circuit. When the input signal is within the transmission range of the circuit, PLL is synchronized (locked) to the input signal. At this point, the output voltage of the decoder drops, and the change .

BA1604 Features

* 1) The detection bandwidth can be varied independently between 0 and 14%. 2) The output circuit can withstand a load current of up to 100mA, and is directly coupled to the logic circuit. 3) The center frequency offers a high level of stability. 4) High out-of-band signal and noise rejection capabili
