EC3925ETTTS-27.000M TR

Oscillators Overview

The EC3925ETTTS-27.000M TR is a CMOS Quartz Crystal Clock Oscillator (XO) manufactured by Ecliptek. It operates at a nominal frequency of 27.000MHz with an LVCMOS output format. The device requires a 1.8Vdc supply voltage and features a 4-pad ceramic surface mount package measuring 3.2mm x 5.0mm. Key electrical specifications include a maximum frequency tolerance/stability of ±25ppm across the operating temperature range of -40°C to +85°C. The duty cycle is specified as 50% ±5%, with rise and fall times not exceeding 6ns. The component supports tri-state functionality via Pin 1 for enable/disable control.

Oscillators Feature Summary

• LVCMOS output interface compatible with standard digital logic circuits
• Tri-state control pin allows for high-impedance disable mode to reduce power consumption
• RoHS compliant lead-free construction suitable for environmentally regulated manufacturing processes

Oscillators Applications

• General clock signal generation in embedded systems
• Reference clock sources for communication interfaces
• Timing synchronization in industrial electronic equipment

Oscillators Procurement Notes

Verify that the specific part number matches the required 1.8V supply voltage and 27.000MHz frequency, as the EH39 series offers various frequencies and voltages. Confirm the tape and reel packaging requirement aligns with automated assembly capabilities. Ensure compliance with RoHS directives is documented for the specific batch. Cross-reference the operating temperature range (-40°C to +85°C) against the final application environment to guarantee stability under all expected thermal conditions.

Oscillators Selection Notes

Select this oscillator when a 1.8V supply and 27MHz LVCMOS output are required within a compact 3.2x5.0mm footprint. Consider the ±25ppm total stability specification for applications sensitive to frequency drift over temperature and voltage variations. Evaluate the tri-state feature if system-level power management requires clock gating. Compare against other Ecliptek series like EC26 or EH39 if different voltage levels or package sizes better suit the board layout constraints.

Oscillators Part Context

This component belongs to the Ecliptek EH39/EC39 series of ceramic surface-mount oscillators. These devices are designed for general-purpose timing applications requiring stable clock signals. The series typically includes variants with different nominal frequencies, supply voltages, and temperature ranges, all sharing similar physical dimensions and LVCMOS output characteristics. The manufacturer emphasizes compliance with environmental standards such as RoHS.

Oscillators Replacement Considerations

Direct substitutes must match the 27.000MHz frequency, 1.8V supply, LVCMOS output, and 3.2x5.0mm SMD package. Verify that any alternative component maintains the ±25ppm stability and -40°C to +85°C operating range. Check for identical pinout configurations, specifically the tri-state function on Pin 1, to ensure circuit compatibility without redesign.
