Webcrystal. Crystal parameters The most popular use of a VCXO is in a PLL application, as shown in Figure 1. The electrical equivalent circuit of the quartz crystal used in the VCXO is shown in Figure 2. C1, L1 and R1 are called the motional parameters of the crystal, and C0 is the shunt capacitance. C0 is real—it can actually be measured with Webby modified crystal fabrication and by adding capacitance or inductance external to the crystal. If the CO and C1 are known then the pulling in ppm between two capacitances can be obtained using the following formula. e.g. C1 = 0.020 pF CL1 = 20 pF C0 = 4.5 pF CL2 = 30 pF To obtain AVERAGE pulling per pF about a known load capacitance use

WebApr 7, 2024 · The DMT five-inch Half Round Diamond File ($16.46 at Home Depot) is being marketed specifically for rescuing crystal and glassware. DMT’s Crystal Saver Diamond File ($23.99 at Woodcraft) is similar. WebSo if the crystal driver has infinite impedance, the capacitive load on the crystal is 16 pF. If it has 0 impedance, the load on the crystal is 27 pF. The reality is of course somewhere in between. In reality, for normal typical microcontroller crystals somewhere around 10 MHz (factor of 2 is close enough), 22 pF caps on both sides is a good bet.
