S33305T-20.000-R

Oscillators Overview

The S33305T-20.000-R is a standard crystal oscillator (XO) manufactured by Aker Technology Corp, operating at a fixed frequency of 20.0000 MHz. It utilizes HCMOS output levels and supports a supply voltage range of 1.8V to 3.3V. The device features a frequency stability of ±50 ppm and operates within a temperature range of -40°C to +85°C. It is housed in a compact 4-SMD, No Lead package with dimensions of 3.2mm x 2.5mm x 1.1mm. The component is lead-free and RoHS compliant.

Oscillators Feature Summary

• Provides stable 20MHz clock signals via HCMOS output interface
• Supports wide supply voltage operation from 1.8V to 3.3V
• Designed for surface mount assembly in compact SMD packages
• Operates reliably across extended industrial temperature ranges

Oscillators Applications

• General purpose digital circuit timing references
• Microcontroller clock source generation

Oscillators Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging configuration when ordering. Confirm that the HCMOS output level matches the receiving logic voltage requirements. Ensure the 4-SMD footprint aligns with the PCB land pattern design. Check for RoHS compliance documentation if required by project specifications. Validate the ±50 ppm stability meets the system timing tolerance needs.

Oscillators Selection Notes

Select this model when a 20MHz HCMOS clock signal is required in a small form factor. Consider the 1.8V to 3.3V supply range for compatibility with various logic families. Evaluate the ±50 ppm stability against system jitter requirements. Compare physical dimensions against available board space constraints. Verify temperature range suitability for the intended operating environment.

Oscillators Part Context

This component belongs to the S3330 series of surface mount crystal oscillators from Aker Technology Corp. The series offers various frequencies and output types in standardized SMD packages. The S33305T variant specifically denotes the 20MHz HCMOS version with reel packaging. It serves as a direct replacement for through-hole or larger surface mount oscillators where space is limited.

Oscillators Replacement Considerations

Direct substitutes include other 20MHz HCMOS oscillators in 4-SMD packages with similar electrical characteristics. Verify pinout compatibility before substitution. Check if alternative manufacturers offer equivalent stability and voltage ranges. Ensure mechanical dimensions match the existing footprint to avoid rework.
