Crystal Frequency Multiplier Upto-160MHz Circuit

Introduction

The Crystal Frequency Multiplier Upto-160MHz is a device that allows multiplication of the frequency of input signal. It is used in various applications such as communication systems, testing and measurement equipment, and audio processing systems. The ICS501M IC is a high-performance clock multiplier that allows multiplication up to frequencies of 160MHz. It provides low jitter and low phase noise, making it suitable for high-fidelity audio applications. It is also ideal for high-speed digital interfaces.

The fundamental frequency of such a crystal is a third, fifth or seventh of the operating frequency. If, however, an overtone crystal is used in an oscillator designed for operation on the fundamental, it is doubtful whether the wanted frequency will be generated. Sometimes, there are difficulties in most such cases that make it necessary for oscillator circuit to be modified.

Explanation of Crystal Frequency Multiplier Upto-160MHz

One practical solution for such problems is offered by the circuit in the diagram, which enables frequencies up to 160 MHz to be generated with the use of a fundamental-frequency crystal. The output signal is virtually free of any jitter

The circuit makes use of an IC that contains not only an oscillator but also a phase-locked loop (PLL) controlled frequency multiplier. The associated ROM stores nine different multipliers, which may be selected by appropriate placing of the jumpers in JP1 and JP2 as shown in the table. A 0 in the table indicates that the jumper is linked to earth; a 1, that is linked to the +5 V line; and a x that it should be left open.

The circuit may conveniently be built on the printed-circuit board shown, which is not available ready made. About 20 mA current is drawn by the circuit.

Conclusion

The Crystal Frequency Multiplier using the ICS501M IC is a high-performance device that allows multiplication of input signals up to 160MHz. It provides low jitter and low phase noise, making it suitable for a wide range of applications such as communication systems, audio processing systems, and testing and measurement equipment. Its compact size, high reliability and ease of use make it an ideal choice for both professional and hobbyist applications.
