S33305T-40.000-R

Oscillators Overview

The S33305T-40.000-R is a surface-mount crystal oscillator from Aker Technology Corp, operating at a nominal frequency of 40 MHz. It utilizes HCMOS output levels and maintains a frequency stability of ±50 ppm. The device supports a supply voltage range from 1.8V to 3.3V and features an enable/disable control function. Packaged in a compact 4-SMD, no-lead form factor measuring 3.2mm x 2.5mm x 1.1mm, it operates within a temperature range of -40°C to 85°C.

Oscillators Feature Summary

• Provides stable 40 MHz clock signals with CMOS-compatible output levels for digital logic integration.
• Includes hardware enable and disable functionality to manage power consumption during inactive periods.
• Designed for surface-mount assembly with a lead-free, RoHS-compliant construction.

Oscillators Applications

• General-purpose timing reference for embedded systems requiring standard clock frequencies
• Digital signal processing circuits needing precise HCMOS-compatible clock inputs
• Consumer electronics utilizing low-voltage (1.8V to 3.3V) power domains

Oscillators Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging when ordering. Confirm that the HCMOS output level matches the receiving circuit's voltage thresholds. Ensure the 4-pin SMD footprint dimensions align with the PCB layout. Check for RoHS compliance requirements if applicable to the final product regulations.

Oscillators Selection Notes

Choose this component when a 40 MHz frequency is required with standard CMOS drive strength. Consider the ±50 ppm stability for non-critical timing applications. Evaluate the 1.8V to 3.3V operating range against system power rails. The enable pin feature is beneficial for battery-powered designs requiring sleep modes.

Oscillators Part Context

This part belongs to the S3 series of surface-mount oscillators from Aker Technology. It shares the physical package and basic electrical characteristics with other variants like the S33305T-20.000-R and S33305T-33.333-XR, differing primarily in output frequency and specific ordering suffixes for packaging or tolerance variations.

Oscillators Replacement Considerations

Direct substitutes include other 40 MHz HCMOS oscillators in 4-SMD packages from Aker, such as the S33305T-40.000-CT. Verify pin compatibility and electrical specifications before swapping with components from different manufacturers.
