Oscillators
Piezoelectric components

A piezoelectric oscillator is a periodic signal source stabilized by a resonator. The first question that comes to mind is: which oscillator should I choose for which application?

Various output signal forms are accessible, such as sinusoidal (level 0 to 7 dBm), C-compatible MOS (Comple-mentary Metal Oxide Semiconductor) (V_a = 12 V, V_o 5 to 10 V), HC MOS (V_a = 5 V, V_o = 5 V), TTL (Transistor-Transistor Logic) (V_a = 5 V, V_o = 3.5 V) up to 100 MHz and ECL (Emitter Coupled Logic) (V_a = - 5 V, V_o = - 1) for frequencies of a few hundred megahertz.

TTL or MOS signals are defined by low and high levels and duty cycle, e.g. V_B < 0.3 V, V_H > 3.3 V, r_c = 50% ± 10%.

Sinusoidal outputs will be characterized by power (dBm), harmonic level and spectral density of phase...
