EG-2121CA 125.0000M-LHPNB

Oscillators Overview

The EG-2121CA 125.0000M-LHPNB is a Surface Mount SAW Oscillator manufactured by Epson Timing, operating at a nominal frequency of 125 MHz. It utilizes LVDS output format and functions within a supply voltage range of 2.375 V to 2.625 V. The device supports an Enable/Disable control function and maintains a frequency stability of ±100 ppm across the commercial temperature range of 0°C to +70°C. It is housed in a compact 6-SMD, No Lead package with dimensions of 7 mm length, 5 mm width, and 1.2 mm height.

Oscillators Feature Summary

• SAW technology provides low-jitter performance suitable for high-speed digital applications.
• LVDS output interface ensures signal integrity and noise immunity.
• Integrated Enable/Disable functionality allows for power management control.

Oscillators Applications

• High-speed data communication interfaces
• Clock distribution networks
• Digital signal processing systems

Oscillators Procurement Notes

Verify the specific suffix LHPNB to confirm LVDS output and ±100 ppm stability. Ensure the design accommodates the 2.375 V to 2.625 V supply range. Confirm that the 0°C to +70°C operating temperature meets environmental requirements. Check for RoHS compliance status if required by project specifications.

Oscillators Selection Notes

Select this component when LVDS signaling is required for the 125 MHz clock source. Consider the ±100 ppm stability requirement against system timing budgets. Evaluate the 6-SMD package footprint against PCB space constraints. Verify that the Enable/Disable pin usage aligns with system power sequencing needs.

Oscillators Part Context

This part belongs to the EG-2121CA series of standard oscillators from Epson Timing. The series offers various output formats and stability options. The 125 MHz frequency is common for Ethernet and PCIe applications. The SAW construction differentiates it from crystal-based alternatives in terms of startup time and shock resistance.

Oscillators Replacement Considerations

Direct substitutes include EG-2121CA 125.0000M-LHPAL0, which shares the same frequency, package, and LVDS output but may differ in packaging or specific stability tolerances. Cross-reference datasheets to ensure electrical compatibility before substitution.
