Professional Insights

For 5G applications, always characterize the complete clock chain including buffers and dividers. The YXC differential oscillators provide excellent raw performance, but system-level jitter depends on the entire clock distribution network. Use differential signaling for all high-speed clocks, implement proper power supply filtering with ferrite beads, and keep differential traces matched in length. Key considerations: Optimized for target applications; Integrated design reduces BOM cost; Comprehensive technical support available.

Frequently Asked Questions

What is the relationship between phase noise and jitter?

Jitter is the time-domain representation of phase noise. Phase noise is measured in frequency domain (dBc/Hz). RMS jitter is calculated by integrating phase noise over a specific bandwidth (typically 12kHz-20MHz).

How do I terminate LVDS outputs properly?

Place a 100Ω differential termination resistor across the output pair at the receiver. Keep traces short (<2 inches) and matched in length within 5 mils. Use proper differential routing with consistent spacing.

Can I use YXC oscillators for synchronous Ethernet?

Yes, YXC oscillators with ±25ppm or better stability are suitable for SyncE applications. For Stratum 3 compliance, select ±4.6ppm stability options or use with external PLL. For more detailed information and application guidance, please consult the product datasheet or contact our technical support team.

What power supply filtering is needed for low jitter?

Use a ferrite bead in series with VDD, followed by 10μF and 0.1μF capacitors to ground. Place the 0.1μF capacitor within 2mm of the oscillator. This filtering maintains performance with noisy supplies.

How do I measure phase noise accurately?

Use a dedicated phase noise analyzer or spectrum analyzer with phase noise measurement capability. Ensure the oscillator has warmed up for at least 30 minutes. Use low-noise power supplies for measurements.
