WebAug 6, 2005 · crystal to give the same voltage reading. The resistor value that gives the same reading as the crystal did is equal to the crystal esr. You really need a tuneable generator with a good vernier to do this, but it works. The reason I chose a 20 ohm resistor was because this was a ball park value of what I expect a 20Mhz crystal esr to be. WebThe ESR resembles the resistive losses of the crystal. Since the ESR attenuates a signal, it has to be overcome by the crystal stage of the attached device to start an oscillation. For the CDCE9xx Family, the maximum ESR that can be overcome is 100 Ω. Any ESR value below 100 Ωprovides a stable oscillation. Another effect of the ESR is the ...
