EC3945ETTTS-25.000M TR

Oscillators Overview

The EC3945ETTTS-25.000M TR is a standard clock oscillator manufactured by Ecliptek, operating at a nominal frequency of 25.000 MHz. It features an LVCMOS output format and operates within a supply voltage range of 1.8V to 3.6V. The device supports tri-state functionality with enable/disable capabilities. It is housed in a 4-pin surface-mount ceramic package measuring 3.2mm x 5.0mm. The unit complies with RoHS standards and functions across a temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Supports tri-state output with dedicated enable and disable functions for power management
• Utilizes LVCMOS output logic compatible with standard digital interfaces
• Constructed in a compact ceramic surface-mount package suitable for automated assembly

Oscillators Applications

• General-purpose clock signal generation in embedded systems
• Timing reference for microprocessors and digital logic circuits
• Communication interface synchronization in consumer electronics

Oscillators Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails. Ensure the ceramic SMD footprint matches the PCB layout constraints. Check for any updated datasheets regarding frequency stability tolerances before finalizing the bill of materials.

Oscillators Selection Notes

Select this component when a low-voltage 25 MHz clock source is required with active control capabilities. The LVCMOS output is suitable for direct interfacing with most modern digital ICs. Consider the ceramic package for better thermal performance compared to plastic alternatives. Verify that the 50ppm stability specification meets the timing accuracy requirements of the application.

Oscillators Part Context

This oscillator belongs to the EC39 series from Ecliptek, designed for surface-mount applications. It serves as a replacement or alternative to older plastic-packaged oscillators like the EC33 series, which has been discontinued. The series emphasizes compliance with environmental standards while maintaining standard form factors for easy integration into existing designs.

Oscillators Replacement Considerations

The EC33 series is officially listed as discontinued with recommended replacements being the EC27 or EC37 series. Direct substitution requires verifying pin compatibility and electrical specifications against the new part number.
