AI Overview
Key Characteristics
- Frequency: 3.579545 MHz (often rounded to 3.579MHz).
- Package: HC-49U (Standard, through-hole, metal can).
- Type: Passive crystal resonator.
- Application: Timing, clock generation, video systems (like NTSC).
- Features: High precision, excellent stability, good aging characteristics, easy to integrate.
What It Does
- It vibrates at its specific frequency (3.579MHz) when an electrical voltage is applied, thanks to the piezoelectric effect of quartz.
- This vibration creates a highly stable electrical signal, acting as the "heartbeat" or clock for electronic circuits.
Why This Frequency?
- 3.579545 MHz is a key frequency in analog television (NTSC) color subcarrier generation, making these crystals common in older video equipment, cameras, and related timing circuits.
In Summary
You're looking at a dependable, through-hole crystal oscillator for creating precise timing in electronics, especially useful where stable, accurate frequencies are needed, like in video or general microcontroller applications.
