Frequency Multiplier Using IC-555 and OP AMP IC-741 Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12096
Indian Lab Suppliers supplies the Frequency Multiplier Using IC-555 and OP AMP IC-741 (Product ID: 12096) as part of its electronics engineering lab equipment range. It is a board that multiplies an input frequency by five using a phase-locked loop with a divider in its feedback path.
Quick Answer
A 565 PLL locks its VCO to the input signal while a 7490 counter, driven through a transistor, divides the VCO output by five before it reaches the phase detector, so the VCO settles at five times the input frequency. A square-wave generator, ±10 V (100 mA) and 5 V (50 mA) regulated supplies are built in. Students check the multiplied output on a digital frequency counter or dual-trace CRO, with a sine/square wave generator as an external source. The board is described with the 565 PLL and 7490 counter; if a 555/741-based version is required, please confirm the configuration at quotation.
