The Benefits of Low-Power High-Speed Current Steering Logic Oscillators
As High-Speed Current Steering Logic (HCSL) clock drivers are being more widely adopted by next-generation advanced interfaces, there is an emphasis for reduced power consumption. Low-Power HCSL (LP-HCSL) was developed to offer a power-saving alternative with high stability, meeting the needs of SSDs, industrial control boards, and other power-conscious applications.
Advantages of Low Power HCSL Oscillators
Enhanced Low Power Consumption
In high-performance computing, data centers, servers, and networking equipment, increasing system density drives a strong demand for overall power efficiency. Although clock signals consume only a small fraction of the total system power, minimizing their current usage contributes to better overall power management and aids in controlling thermal output across the system.
Extends Battery Life in Embedded and Mobile Systems
While HCSL is commonly found in fixed systems, LP-HCSL is well-suited for embedded systems, automotive controllers, and certain industrial PCs. In applications that rely on batteries or operate under power constraints, LP-HCSL oscillators offer significant benefits in terms of energy efficiency and extended battery life.
Supports Green Design and ESG Goals
Major OEMs and data center operators are increasingly prioritizing energy efficiency and reducing their carbon footprint. Selecting LP-HCSL helps suppliers in aligning with sustainable design goals and achieving corporate ESG (Environmental, Social, and Governance) objectives.
Real World Power Savings
LP-HCSL is the ideal choice for engineers seeking power-efficient clocking solutions in modern high-speed applications, helping extend battery life, reduce system power, and contribute to sustainable design.
For example, comparing 100 MHz 3.3 V HCSL and LP-HCSL oscillators shows clear differences in current consumption. Every reduction helps contribute to lower system power and thermal load.
