Low Power HCSL ClearClock™ Oscillators: Energy-Efficient Timing with Enhanced Performance

Abracon’s Low Power HCSL (LP-HCSL) ClearClock™ Differential Oscillators extend the capabilities of the ClearClock® product line, offering high-performance timing solutions with significantly reduced power consumption. Available in industry-standard 2016, 2520, and 3225 package sizes, these oscillators operate with typical supply currents as low as 12-15mA, making them ideal for energy-conscious applications such as data centers, industrial automation, and other PCIe-based interfaces

Advantages of Low Power HCSL ClearClock™ Oscillators

1. Significant Power Savings - Traditional HCSL drivers are known for their high power consumption. LP-HCSL technology minimizes this, making it ideal for applications where energy efficiency is crucial, such as optical transceivers and storage systems.
2. Optimized Signal Performance and Jitter Reduction - With an ultra-low phase jitter of 100fs typical at 100MHz, these oscillators provide exceptional signal integrity, ensuring reliable high-speed data transmission with minimal noise. Their 3rd overtone quartz crystal design further enhances stability.
3. Integrated Termination Resistors for Simplified Design - Unlike traditional HCSL drivers, which require additional external components, LP-HCSL oscillators have built-in termination resistors. This feature reduces Bill of Material (BOM) costs, simplifies PCB routing, and saves valuable board space.
4. Superior Board Layout Flexibility - LP-HCSL oscillators improve performance when driving lengthy traces and simplify AC-coupling, making them an excellent choice for designs with complex signal transmission requirements. Their compact form factor ensures optimized board layout without sacrificing functionality.

Industry Use Cases and Advantages

Designed specifically for PCIe-based systems, these oscillators are critical in high-performance computing and data infrastructure:

• Data Centers, Servers, and Storage Systems – Provide precise timing for PCIe connections between NICs, FPGAs, CPUs, GPUs, and storage controllers, ensuring seamless high-speed data processing.
