S2M025T-27.000-X-R

Oscillators Overview

The S2M025T-27.000-X-R is a 27 MHz crystal oscillator (XO) manufactured by Aker Technology Corp, featuring HCMOS output levels and a supply voltage range of 1.62V to 3.63V. It utilizes a 4-SMD, no-lead surface-mount package with dimensions of 2.5mm x 2.0mm x 0.9mm. The device supports enable/disable functionality and operates within a temperature range of -40°C to +85°C.

Oscillators Feature Summary

• HCMOS output signal compatibility for digital logic interfacing
• Integrated enable and disable control pin for power management
• Ultra-miniature surface-mount package design for space-constrained applications

Oscillators Applications

• General-purpose timing reference for microprocessor-based systems
• Clock source for telecommunications equipment
• Timing component in data storage and delivery devices
• Reference oscillator for computer products and instrumentation

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the HCMOS output swing matches the receiving circuit's input thresholds. Ensure the enable/disable pin configuration aligns with the system's power sequencing strategy to prevent unintended oscillation or noise during startup.

Oscillators Selection Notes

Select this component when a standard HCMOS output is required rather than LVCMOS or differential signals. Consider the ±25ppm stability if tight frequency accuracy is needed over the operating temperature range. Evaluate the 1.62V minimum supply voltage to ensure compatibility with low-voltage logic families. The 4-pin no-lead package requires appropriate PCB land pattern design for reliable soldering.

Oscillators Part Context

This part belongs to Aker Technology's S2M series of ultra-miniature CMOS oscillators. The series is designed for high-volume consumer and industrial electronics where small form factors are critical. It complements the manufacturer's broader portfolio of TCXOs and VCXOs, offering a cost-effective solution for applications not requiring active frequency tuning.

Oscillators Replacement Considerations

Direct substitutes include other 27MHz HCMOS oscillators in 4-SMD packages from manufacturers such as Epson, NDK, or SiTime. Verify pinout compatibility, specifically the enable pin location, as pin assignments vary across brands. Ensure replacement parts meet the same ±25ppm stability and -40°C to +85°C temperature range specifications.
