The HC49/US crystal oscillator is a passive frequency control component used to provide a stable reference clock for electronic circuits.
It operates by mechanical resonance of a quartz crystal to generate a precise frequency signal.
The frequency is selectable by the buyer to match specific system requirements.
This oscillator is commonly used in microcontrollers, microprocessors, communication devices, and timing circuits.
The through-hole HC49/US package allows easy mounting and reliable mechanical stability.
