S218025T-50.000-R

Oscillators Overview

The S218025T-50.000-R is a standard crystal oscillator (XO) manufactured by Aker Technology Corp, designed for surface-mount applications. It operates at a fixed frequency of 50.0000 MHz with an output tolerance of ±25 ppm and a load capacitance of 15 pF. The device utilizes HCMOS logic levels with a 55% duty cycle and functions on a single 1.8V supply voltage. It features enable/disable control capabilities and is housed in a compact 4-SMD, no-lead package suitable for automated assembly.

Oscillators Feature Summary

• HCMOS output interface with enable/disable functionality
• Ultra-miniature 4-pin surface-mount form factor
• Single 1.8V power supply operation

Oscillators Applications

• Microprocessor-based system clocking
• Telecommunications equipment timing
• Data storage and delivery systems

Oscillators Procurement Notes

Verify the specific ordering suffix to confirm frequency accuracy and package variant. Ensure the procurement documentation explicitly states RoHS compliance and lead-free status as indicated by manufacturer listings. Cross-reference the part number against official Aker Technology catalogs to distinguish between standard XO variants and specialized automotive or temperature-compensated versions within the same series.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V HCMOS clock source is required for space-constrained designs. The 4-SMD package facilitates high-density PCB layouts. Consider the ±25 ppm stability specification against system timing requirements. Verify that the enable/disable pin configuration aligns with power management strategies in the target application circuit.

Oscillators Part Context

This oscillator belongs to Aker Technology's ultra-miniature CMOS and differential XO product line, which targets wide temperature change environments. The S218025 series represents standard frequency control solutions distinct from their TCXO and VCXO offerings that provide tighter stability. It serves general electronics industries including computer products and instrumentation.

Oscillators Replacement Considerations

Direct substitutes include other 50MHz HCMOS oscillators in 4-SMD packages with 1.8V operation, such as the S218025T-48.000-R for different frequency needs. Verify pin compatibility and electrical specifications before substitution.
