Features of SMD HCSL Differential Oscillator 7050
Improved interference immunity
Differential signals have phase symmetry, effectively canceling out external electromagnetic interference (EMI) and improving signal quality.
Longer transmission distance
Differential signal current is transmitted over two lines, reducing the impact of electrical noise on the signal, allowing it to be transmitted over longer distances.
Enhanced data integrity
The high stability of differential signals reduces data errors caused by signal distortion, which is particularly important in high-speed data communications.
Advantages of SMD HCSL Differential Oscillator 7050
Strong Anti-Interference Capability
Differential signaling is highly immune to electromagnetic interference (EMI). When external noise affects both ends simultaneously, the voltage difference remains stable, ensuring that the clock signal is not disturbed.
Excellent Signal Integrity
The output has a sharp rising edge and stable swing, allowing it to directly drive high-speed SerDes links, FPGA clock trees, or multiple synchronized ADCs, reducing signal distortion.
Compatible with Mainstream High-Speed Interfaces
HCSL is the clock output format recommended by the PCIe standard and is widely used in motherboards, servers, and enterprise network equipment, simplifying system design.
Customization Support
Voltage, frequency, and jitter level can be customized to meet the individual needs of different application scenarios.
Applications of SMD HCSL Differential Oscillator 7050
-
PCIe System Clock
Provides 25MHz and 100MHz reference clocks for PCIe Gen1-Gen4 motherboards, ensuring high-speed data transmission synchronization when used with Intel Xeon and AMD EPYC platforms.
-
Industrial and Communications Equipment
In 5G base stations, network communication modules, and edge computing platforms, the high stability and anti-interference capabilities of the HCSL oscillator improve system reliability.
-
Optical Modules and Ethernet

-
Data Center and Storage
Used in server motherboards, SSD controllers, and high-speed ADC/DAC sampling systems, it provides a low-jitter clock source to ensure data integrity.
How to Choose SMD HCSL Differential Oscillator 7050
Product Quality
Ensure that the oscillators provided by the supplier meet industry standards and offer high stability and low noise performance.
Customization
Many applications require differential oscillators with specific frequencies and configurations, so choosing a supplier that can provide customization is a plus.
Delivery Time
Timely delivery is critical to project schedules, so the supplier’s delivery capabilities and reliability are another factor to consider.
Technical Support
Choose a supplier that offers comprehensive technical support and after-sales service to ensure timely assistance if any issues arise during use.
Test and Verification Key Points
Purpose: Verify that the jitter, rise time, and overshoot of the HCSL signal meet specifications.
Use an oscilloscope (bandwidth ≥ 2 GHz) with a differential probe to capture the signal and observe the eye opening.
Qualification Criteria: Vertical eye opening ≥ 70% of the signal swing, horizontal eye opening ≥ 90% of the unit interval (UI).
Key Parameters:
• Near-End Phase Noise (1 kHz Offset): ≤ -120 dBc/Hz
• Far-End Phase Noise (1 MHz Offset): ≤ -150 dBc/Hz
• Test Tool: Phase noise analyzer (such as the R&S FSWP) or spectrum analyzer with a phase noise test module.
Aging Test: Operate continuously for 1000 hours at 85°C/85% RH, monitoring frequency deviation change (must be ≤ ±10 ppm). Temperature cycle test: 10 cycles between -40°C and +105°C to verify frequency offset recovery capability (temperature drift error ≤ ±5ppm).
