How to Choose a Quartz Crystal Oscillator for the MAX1470 Superheterodyne Receiver

Abstract: Quartz crystals are available from various vendors in a variety of shapes and sizes, and can range widely in performance specifications. Some of these specifications include resonance frequency, resonance mode, load capacitance, series resistance, holder capacitance, and drive level. This application note helps in the understanding of these parameters, allowing the user to specify the crystal that is right for their application and one that will give the best results with the MAX1470 superheterodyne receiver circuit.
