Circuit Specialists stocks a multitude of inexpensive crystal and TTL clock oscillators commonly used as clock signals in digital integrated circuits and as a means of stabilizing frequencies in radio transmitters and receivers. Our crystal oscillators have frequencies ranging from 1.84 to 4.43 MHz and behave as a circuit composed of an inductor, capacitor, and resistor with a precise resonant frequency. Ranging from 4 to 16 MHz, our compact TTL clock oscillators are designed for extreme precision.
