Webexcessive drive to the crystal. Drive Level seen by the Crystal The drive level seen by the crystal can be approximated as: DL=ESR × IQ^2 Where; ESR = equivalent series resistance of the crystal IQ = current flowing the crystal in RMS It is important to note that driving a quartz crystal with a much higher drive may lead to quartz blank heating, WebThe drive level contains variables from both the crystal and oscillator; hence both the crystal type and frequency will affect the drive level. When characterizing an … WebThe drive level of a crystal is a measurement of the power dissipation seen by a crystal in the amplifier circuit of the oscillator. The drive level is expressed in milliwats (mW) or microwatts (µW). The maximum power dissipation is generally specified by the type of quartz used and the manufacturer, with typical ratings up to 1mW or 2mW. t-shirts for women walmart
