Description
The YSX531SL 14.31818 MHz Crystal is a high-precision, 4-pad surface-mount (SMD) quartz resonator. The 14.31818 MHz frequency is an industry-standard reference, specifically chosen for its utility in multimedia and video applications, as it serves as a base frequency that can be divided or multiplied to generate standard NTSC color subcarriers and VGA signal clocks.
The 4-pad design is a significant upgrade over standard 2-pad crystals. By utilizing two pads for the crystal connection and two pads connected directly to the PCB ground plane, this component provides superior electromagnetic interference (EMI) shielding. This grounding mechanism reduces crosstalk and parasitic noise, ensuring that the clock signal remains clean and jitter-free, which is essential for high-fidelity video processing and digital communications.
Key Features
- 4-Pad Grounded Shielding: Internal quartz element is shielded by ground pins, significantly reducing noise and EMI.
- Multimedia Standard: 14.31818 MHz is the foundation for many video-processing and display-timing circuits.
- Ultra-High Precision: 10 PPM tolerance provides the stability required for sensitive timing and synchronization.
- SMD Optimized: Compact 4-pad surface-mount package designed for high-density boards and automated assembly lines.
