Category: Oscillator Circuits / Crystal Views: 68 Rank: 0 I have used this circuit many times when I needed a low frequency reference, which did not draw much power. With the components show, the current from a 3v battery is less than 1.2 microamps. visit page.
Related circuits Wide-Range Crystal Oscillator Circuit A circuit using one 7400 TTL10 can use crystals of the fundamental type, from 1 to about 13 MHz. Output is rich in harmonics, International crystal oscillator International Crystal OF-1 HI oscillator circuit for third-overtone crystals Diagram shows a 50MHz oscillator operating on a third harmonic. The collector"s load resistor R1 has been increased because the quartz crystal"s internal series resistance Rs increases with frequency in the VHF range. The crystal"s internal series resistance Rs is 30ohm, and the transistor"s... Crystal Controlled Time Base Oscillator This is an image Schematic. No Description available. Kick start a crystal oscillator in Spice Starting up oscillator circuits and getting them to maintain oscillation in a Spice simulation is difficult. Some high-frequency crystal circuits require days for the oscillation to reach steady state. Thus, most designers separate the crystal`s circuit simulation from the rest of the system... This simple circuit will oscillate with a wide range of crystals. Connect several different types of crystal holders in Ultra Low Power 32KHz Crystal Oscillator I have used this circuit many times when I needed a low frequency reference, which did not draw much power. With the components show, the current from a 3v battery is less than 1.2 microamps. Crystal-controlled signal source This general purpose signal source serves very well in signal-tracing applications. The output level is variable to more than 1 Vrms into a 50 O load. Almost any crystal in the 1 to 15 MHz range can be used. Ql forms a Colpitis oscillator with the output taken from the emitter. A capacitive...
