Oscillators Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation to confirm packaging details and reel specifications. Ensure the requested part matches the exact 100 MHz frequency and HCMOS output type required by the design. Cross-reference the 4-SMD no-lead footprint dimensions with the PCB layout to guarantee mechanical compatibility. Confirm that the 1.8V to 3.3V supply voltage aligns with the target circuit's power rails before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a precise 100 MHz reference is needed for digital logic circuits requiring HCMOS levels. The integrated enable pin allows for dynamic power control, making it suitable for battery-operated or energy-efficient designs. Consider the ±50 ppm stability requirement against system jitter tolerance. The small form factor fits space-constrained boards, while the wide temperature range ensures performance in harsh environments without additional thermal management.

Oscillators Part Context

This oscillator belongs to the S5 series of ultra-miniature surface-mount devices from Aker Technology. The series focuses on providing reliable timing solutions for portable and high-density electronics. The S51805T variant specifically targets applications demanding low profile and robust performance. It complements the manufacturer's broader portfolio of TCXOs and VCXOs for higher precision needs.

Oscillators Replacement Considerations

Direct substitutes include other 100 MHz HCMOS oscillators in 4-SMD packages with compatible voltage ranges. Verify pinout compatibility and electrical parameters such as load capacitance and stability before substitution. Alternative models may require level shifting if output voltages differ significantly.
