S51805T-125.000-R

Oscillators Overview

The S51805T-125.000-R is a standard crystal oscillator (XO) manufactured by Aker Technology Corp, operating at a nominal frequency of 125 MHz. It utilizes HCMOS output logic and functions with a 1.8V supply voltage. The device features an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package, specifically the SMD5032-4P form factor, designed for surface-mount assembly.

Oscillators Feature Summary

• Provides precise 125 MHz frequency generation using HCMOS output signals
• Integrates enable and disable functionality for active power control
• Operates on a low-voltage 1.8V power supply rail
• Utilizes a compact 4-pin surface-mount package for space-constrained designs

Oscillators Applications

• High-speed digital signal processing circuits requiring stable clock sources
• Embedded systems utilizing 1.8V logic families
• Communication modules needing precise timing synchronization
• Portable electronic devices prioritizing low power consumption

Oscillators Procurement Notes

Verify that the target design supports 1.8V logic levels, as this component does not operate at standard 3.3V or 5V rails. Confirm the PCB footprint matches the SMD5032-4P dimensions to ensure proper solder joint formation. Check that the application circuitry can handle HCMOS output characteristics without additional buffering if required by the load capacitance specifications.

Oscillators Selection Notes

Select this model when a 125 MHz clock source is required within a 1.8V system architecture. It is suitable for applications where size constraints necessitate a 5.0mm x 3.2mm package. Consider alternative models from the same series if different output types like LVDS are needed or if higher supply voltages are mandated by the system design.

Oscillators Part Context

This part belongs to the S51805T series of surface-mount oscillators from Aker Technology Corp. The series offers various frequency options within the SMD5032-4P package. These components are designed to replace through-hole crystals in modern high-density PCB layouts, providing factory-calibrated stability without external tuning components.

Oscillators Replacement Considerations

Direct replacements must match the 125 MHz frequency, 1.8V supply, and HCMOS output type. Verify pin compatibility for the 4-SMD No Lead configuration. Models such as S51805T-125.000-X-R may offer similar electrical performance but require confirmation of specific tolerance and load capacitance differences before substitution.
