Ultra-low jitter differential oscillator with LVDS output for 10G Ethernet and high-speed communications. Sub-0.3ps R...
Product Overview
Description
The YXO-D-156M25 is a high-performance differential oscillator designed for demanding high-speed applications. With 156.25MHz output and LVDS signaling, this oscillator is ideal for 10G Ethernet, Fiber Channel, and high-speed SerDes clocking applications.
The standout feature is the ultra-low jitter performance of less than 0.3ps RMS and excellent phase noise of -145dBc/Hz at 1MHz offset. These specifications ensure reliable operation of high-speed data converters and minimize bit error rates in communication systems.
The differential LVDS output provides excellent noise immunity and reduced EMI compared to single-ended signals. The integrated LDO regulator provides excellent power supply rejection, maintaining performance even with noisy system power rails.

Frequently Asked Questions
How do I terminate the LVDS output?
Place a 100Ω differential termination resistor across OUT+ and OUT- at the receiver end. Keep traces short (<2 inches) and matched in length. Use proper differential routing with consistent spacing. For detailed specifications and application support on yxc YXO-D-156M25, refer to the datasheet or contact our team.
What is phase noise and why does it matter?
Phase noise measures frequency stability in the frequency domain. Lower phase noise (more negative dBc/Hz) means cleaner spectral purity. It's critical for high-speed communications as it affects bit error rates and system EVM.
Can I use this for PCIe clocking?
PCIe requires HCSL output, not LVDS. Use the YXO-D-156M25-HCSL version for PCIe applications. The electrical specs are similar but the output driver is compatible with PCIe requirements. For detailed specifications and application support on yxc YXO-D-156M25, refer to the datasheet or contact our team.
How do I measure jitter accurately?
Use a high-bandwidth oscilloscope (>1GHz) with jitter analysis software or a dedicated phase noise analyzer. For RMS jitter, integrate phase noise from 12kHz to 20MHz offset. Ensure proper probing to avoid measurement errors.
What power supply filtering is recommended?
Use a ferrite bead in series with VDD followed by a 10μF and 0.1μF capacitor to ground. Place the 0.1μF capacitor as close to the oscillator as possible. This filtering maintains performance with noisy supplies.
