A better indicator of achievable receiver range performance is usually given by its selectivity, often stated as intermediate frequency (IF) or radio
frequency (RF) bandwidth, depending on receiver topology. Selectivity is a measure of the rejection by the receiver of ambient noise. More selective

resistance is too great, the oscillator may oscillate at a diminished peak-to-peak level, or may fail to oscillate entirely. Micrel recommends that series
resistances for ceramic resonators and crystals not exceed 50Ω and 100Ω respectively. Refer to “Application Hint 35” for crystal recommendations.
