Time-Base Oscillator for RTC ICs
... using a crystal with this load capacitance specification, the RTC will resonate much closer to the anti-resonant frequency, Fa. Thus, a larger trim capacitor is necessary. Benchmarq suggests using a 10pF from the X2 pin to ground in order to achieve ± 30 ppm accuracy. Please take into consideration ...

... In analogue synthesis, a few basic waveforms are used for the source of sounds; sine, triangle, square, sawtooth and pulse. A sine wave is most basic waveform and is the building block of harmonic analysis. This is because a sine wave has no harmonics (overtones) at all. It only has the tone of the ...
