EC5645ETTTS-20.000M TR

Oscillators Overview

The EC5645ETTTS-20.000M TR is a standard quartz clock oscillator (SPXO) from the Ecliptek EC56 series, housed in a compact 2.0mm x 2.5mm ceramic surface-mount package. It operates at a nominal frequency of 20MHz with LVCMOS output format and requires a 3.3Vdc supply voltage. The device features a total frequency stability of ±50ppm, inclusive of calibration tolerance, temperature drift, voltage changes, load variations, first-year aging, and mechanical shock/vibration effects. It supports an industrial operating temperature range of -40°C to +85°C and includes a tri-state control function for low-power standby modes.

Oscillators Feature Summary

• Compact 2.0mm x 2.5mm ceramic SMD footprint suitable for space-constrained designs
• LVCMOS output compatible with standard CMOS logic levels
• Tri-state pin enables high-impedance mode for power reduction
• Comprehensive frequency stability covering all operational environmental factors

Oscillators Applications

• Industrial control systems requiring stable timing references
• Embedded microcontroller clock sources
• Data communication interfaces
• Portable battery-powered devices utilizing tri-state power saving

Oscillators Procurement Notes

Verify that the specific part number matches the required industrial temperature grade (-40°C to +85°C) and the ±50ppm stability specification. Confirm the package dimensions align with the PCB land pattern for the 2.0mm x 2.5mm footprint. Ensure the design accounts for the 3.3V supply voltage tolerance and LVCMOS output characteristics. Cross-reference the manufacturer's latest datasheet for any updates on compliance certifications or pin configurations before finalizing procurement.

Oscillators Selection Notes

Select this component when a small form factor is critical alongside robust industrial temperature performance. The ±50ppm stability is suitable for general-purpose digital circuits but may be insufficient for high-speed serial interfaces requiring tighter tolerances. Consider the tri-state feature if system-level power management requires clock gating. Compare against other EC56 variants if different frequency stabilities or commercial temperature ranges better fit the application constraints.

Oscillators Part Context

This oscillator belongs to the Ecliptek EC56 series, which focuses on providing reliable clock solutions in ultra-small packages. The series offers various frequency options and stability grades within the same 2.0mm x 2.5mm footprint, allowing designers to maintain consistent board layouts while adjusting electrical specifications. The EC5645ETTTS variant specifically denotes the industrial temperature range and tri-state capability within this family.

Oscillators Replacement Considerations

Direct substitutes within the same series include EC5645TTS-20.000M TR for commercial temperature range or EC5645ETTS-20.000M TR if tri-state functionality is not required. Verify compatibility with existing firmware and hardware timing requirements when switching between stability grades or temperature ranges.
