Electronic crystal oscillator pcb layout guidelines are the secret sauce that makes this possible. The output clock signal from a Schmitt-trigger oscillator or a 555 timer is controlled using an RC time constant. The problem with using these circuits is that the resistor and capacitor values do not stay constant over time. The layout of a clock generator impacts the performance of the clock receivers and the nearby components on the circuit board. Many times a system designer has to manually implement placement and routing for devices such as clock generators, power supply and crystal oscillator capacitors, and termination resistors.
