EC2745ETTTS-25.000M TR

Oscillators Overview

The Ecliptek EC2745ETTTS-25.000M TR is a standard CMOS crystal oscillator operating at a nominal frequency of 25.000 MHz. It utilizes a 2.5V supply voltage and features an LVCMOS output format within a 5.0mm x 7.0mm 4-pad ceramic surface-mount package. The device provides a frequency stability of ±50 ppm across the industrial temperature range of -40°C to +85°C, inclusive of calibration tolerance, temperature drift, voltage variation, load changes, aging, and vibration effects. It supports tri-state control for enable/disable functionality and complies with RoHS and REACH standards.

Oscillators Feature Summary

• Integrated tri-state control pin allows for active output enablement or high-impedance disable mode to reduce power consumption during standby periods.
• Comprehensive frequency stability specification aggregates all environmental and operational variances into a single guaranteed tolerance value.
• Robust ceramic surface-mount construction ensures mechanical reliability and thermal resistance suitable for demanding industrial environments.

Oscillators Applications

• Industrial data acquisition gateways requiring precise timing synchronization
• Communication equipment clock sources for Ethernet or serial interfaces
• Embedded systems utilizing microcontrollers or digital signal processors

Oscillators Procurement Notes

Verify that the specific part number matches the required stability grade and package dimensions for your design. Confirm compliance with current environmental directives such as RoHS and REACH if exporting to regulated markets. Ensure the power supply circuit includes appropriate decoupling capacitors near the VDD pin to maintain signal integrity and minimize jitter. Check that the PCB footprint aligns exactly with the manufacturer's recommended land pattern to prevent soldering defects.

Oscillators Selection Notes

Select this component when a 2.5V logic interface is required alongside moderate frequency stability in a compact form factor. Consider the ±50 ppm stability rating against system timing budgets, particularly for high-speed serial links. Evaluate the power consumption characteristics if battery operation is a constraint, noting the low standby current in disabled mode. Compare physical dimensions against available board space to ensure the 5.0mm x 7.0mm package fits within the mechanical envelope.

Oscillators Part Context

This oscillator belongs to the EC27 series from Ecliptek, designed for general-purpose clock generation in electronic circuits. The series offers various frequency options and stability grades to suit different application requirements. It serves as a direct replacement for older discontinued plastic packages like the EC33 series, providing improved thermal performance and reliability through its ceramic construction.

Oscillators Replacement Considerations

The EC33 series is officially discontinued; the EC27 series is the designated replacement. Verify pinout compatibility and electrical specifications before substitution.
