EC3645ETTTS-25.000M TR

Oscillators Overview

The EC3645ETTTS-25.000M TR is a standard clock oscillator from the Ecliptek EC36 series, operating at a nominal frequency of 25 MHz with LVCMOS output format. It functions on a 3.3 VDC supply voltage and provides a frequency stability of ±50 ppm. The device supports an enable/disable function and features tri-state capability. Designed for surface mount applications, it utilizes a 4-pad ceramic package measuring 3.2 mm by 5.0 mm. The component complies with RoHS standards and operates within a temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Supports active enable and disable functionality via control input
• Features tri-state output for high impedance state management
• Utilizes a compact 3.2mm x 5.0mm ceramic SMD package

Oscillators Applications

• Industrial gateway Ethernet reference clocks
• System clocks for microcontrollers
• ADC sampling reference clocks

Oscillators Procurement Notes

Verify that the ordering suffix matches the specific tolerance and temperature grade required for the application. Confirm the presence of the 'E' suffix in the part number indicates the enable/disable pin configuration. Ensure the procurement documentation specifies the tape and reel packaging format as indicated by the 'TR' designation. Cross-reference the manufacturer part number against official Ecliptek or Abracon catalogs to confirm current production status and compliance certifications.

Oscillators Selection Notes

Select this component when a 25 MHz LVCMOS signal is required with ±50 ppm stability across industrial temperatures. Consider the power consumption profile, which increases significantly above 10 MHz, ensuring the system power budget accommodates the load. Verify that the 15 pF load capacitance requirement aligns with the connected circuitry inputs. This model is suitable for designs requiring pin-compatible replacement options within the broader EC36 family.

Oscillators Part Context

This oscillator belongs to the EC36 series, a line of standard quartz crystal oscillators manufactured by Ecliptek, now part of Abracon. The series offers various frequencies and stability grades in a common 5032 footprint. The EC3645ETTTS variant specifically denotes the 3.3V operation, enable pin feature, and industrial temperature range capabilities within this product family.

Oscillators Replacement Considerations

Officially recommended replacements for discontinued EC33 series components include EC27 or EC37 series models. For direct functional substitution within the same form factor, other EC36 series variants with matching frequency and stability specifications should be evaluated.
