BA1604 Description
munication 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 parator 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...
