The operating frequency range of the CD4046 is from 0 to 1 MHz, and the PLL can be well adapted in this frequency range. Phase-locked loop circuit when used as a frequency selection, its frequency selection frequency is mainly determined by the external capacitor values ​​between the 6 and 7 feet and 11-pin external resistance value, as long as the parameters of these components are selected, the phase-locked loop The center frequency of the VCO is determined and the frequency of the PLL is determined. This feature of the PLL can be applied to the channel selection circuit of the remote receiver. For example, when we use it for a channel selection circuit of a dual-channel remote control receiver, only the center frequency of the selected channel is selected, and the external capacitance value corresponding to the center frequency between its pinets 6 and 7 can be selected. The composition of this circuit is shown in the figure.
(a) is a remote control transmitter circuit; (b) is a receiver circuit.
The products can provide various specifications of rectifier bridge devices according to customer requirements. The electrical properties, appearance, reliability, safety indicators and environmental protection indicators of the products all meet the relevant standards.
