application note addresses issues commonly raised during the selection of the reference crystal, typically 14.318 MHz, for Chrontel's product line. Pierce Oscillator A simplified schematic of the oscillator circuit used in Chrontel products is shown in Figure 1. Note that the typical 2-pin crystal has been replaced
