Today, the majority of electronic circuits (including microprocessors, microcontrollers, FPGAs, and CPLDs) are based on clocked logic, requiring a timing source. Depending on the frequency accuracy ...
[Paul] likes a precise oscillator. His recent video shows a crystal oscillator with a “watch crystal” and a CMOS counter, the CD4060. Using such a circuit can produce very stable frequencies and since ...
Crystal oscillators are incredibly useful components, but they come with one little snag: their oscillation is temperature-dependent. For many applications the relatively small deviation is not a ...
Another great crystal oscillator circuit with BB139, a 2-nd harmonic quartz crystal and one BF214 transistor. So, the Q quartz is half of the desired transmitter frequency, L1 has 24 turns, 0.08mm Ø ...
Starting a crystal oscillator fast in an IoT node is an art: the high Q needed for stability means they take milliseconds to get going, just to transmit a 128μs Bluetooth LE packet, and power is at a ...
The evolution of precision clocks. The tradeoffs between MEMS vs. crystal oscillators. The manufacture and cost issues involved. Almost every electronic device you can imagine depends on a precision ...
Said to consume 10 times less power than comparable circuits, the EM7604 CMOS crystal oscillator is intended for use with a 32.768 kHz tuning fork crystal as a low-frequency clock oscillator with no ...
AN article on this subject by I.E. Fair (Bell Lab. Rec., £\ 21, No. 8; April, 1943) points out that stability is one of the major requirements for oscillators controlling the frequency of radio ...
