NEL晶体振荡器卓越质量与可靠性，NEL Frequency Controls is a technology leader in the development and manufacture of leading edge frequency control products. Customers choose NEL to supply the optimal solution for applications requiring crystal oscillators with challenging performance specifications such as ultra low phase noise, ultra low power, and ultra high frequency capability. NEL’s research and product development efforts support next generation customer applications that push performance boundaries in system speed, bandwidth, resolution, accuracy, and power consumption. Our customers benefit from our broad, low cost product offering, which reflects globally competitive frequency control solutions. Customer technologists can rely on NEL for total technical support in selecting the best frequency control solution for their application.

With state-of-the-art manufacturing locations in the USA and the Philippines, NEL Frequency Controls’ manufacturing model provides the flexibility required to compete globally with its diverse product mix. Frequency control solutions of higher complexity are manufactured at NEL’s USA location, whereas higher volume, lower cost, less complex frequency control solutions are manufactured at NEL’s Philippines location. Both manufacturing locations operate under the same TQM policy with common systems design, process, and testing to ensure complete product integrity. NEL is a ISO 9001-2008 certified company and has a strong industry reputation for high reliability with its products.

Breakthrough Synchronized Crystal Oscillator, SXO

NEL’s synchronized crystal oscillator (SXO) technology offers significant performance advantages for high performance computing requirements. Parallel processing applications that require scalable synchronized clocking now have a better solution than the traditional clock distribution approach. The Synchronized Crystal Oscillator provides:
• Frequency and phase synchronization among an unlimited number of clocks in an HPC timing architecture
• Redundancy—Eliminates the need for master clock resulting in no single point of clock failure risk
• Full scalability—Additional SXO’s can be added (synched) to an existing SXO ensemble
• Reduced system level jitter—Additive jitter associated with clock distribution is eliminated
SXO evaluation boards, white paper, and demonstrations are available upon request.

Lowest Phase Noise Solutions Available

NEL Frequency Controls can optimize crystal oscillator phase noise performance based on customer goals and requirements. Customers looking for a competitive advantage with their application’s phase noise performance will often choose NEL to help gain a performance advantage of -5 dBc/Hz to -10 dBc/Hz. Customers looking for low cost ways to upgrade existing designs and platforms turn to NEL for the flexibility of selecting varying levels of phase noise performance within a drop-in compatible package.

Problem Solving

The crystal oscillator is often described as the heart of the system. Having an optimized frequency control solution for an application requires an understanding of the environment in which the crystal oscillator will be operating. NEL engineers are adept at providing robust solutions that factor in signal integrity issues, such as power supply noise, harmonics, shock and vibration, loading, temperature, and assembly conditions.

Excellent Quality, Reliability

NEL’s Total Quality Management systems embed quality requirements in all processes. Statistical Process Control is used to validate quality at every step of production. Our standard practices include 100% testing. Testing is expanded with HALT/HASS procedures for mission critical applications. NEL provides extensive product characterization data to verify complete compliance with product specifications. Data on long term reliability is available for customer review. Product serialization for added traceability assurance is available upon request.

Just In Time, On Time

NEL’s vertical integration allows for short lead times and just in time delivery. Provide NEL with your forecast, communicate upside demand requirements, and NEL will deliver just in time, on time.

Comprehensive Customer Support

• Immediate phone support, both customer service and technical support
• Access to systems that evaluate the alternatives and pinpoint the best solutions for your needs
• Flexible design solutions to help achieve your goals

• Global partnerships

In the industrial infrastructure market, long-term production support is required, especially in response to measures such as quality customization level libraries. Based on years of accumulated analog circuit technology, we provide products and services that satisfy customers with low phase noise oscillators. At the same time, discussions will also be held on alternative products related to the shutdown of other companies.
