EC3645ETTTS-100.000M TR

Oscillators Overview

The EC3645ETTTS-100.000M TR is a standard quartz crystal clock oscillator (SPXO) manufactured by Ecliptek, part of the EC36 series. It operates at a nominal frequency of 100 MHz with an LVCMOS output format. The device requires a single 3.3 Vdc supply voltage and features a 4-pad ceramic surface mount package measuring 5.0 mm x 7.0 mm. It supports tri-state functionality for enable/disable control via Pin 1. The component is RoHS compliant and lead-free, designed for industrial applications with a specified operating temperature range from -40°C to +85°C.

Oscillators Feature Summary

• Provides stable 100 MHz reference clock signals using quartz crystal technology.
• Integrates tri-state control on Pin 1 to enable or disable the output signal.
• Utilizes a compact 5.0 mm x 7.0 mm ceramic SMD package for surface mounting.
• Delivers LVCMOS output levels compatible with standard digital logic interfaces.

Oscillators Applications

• Industrial gateway systems requiring precise timing references
• High-speed data communication equipment such as Ethernet PHYs
• PCIe interface circuits needing low-jitter clock sources
• Automotive electronics demanding wide temperature stability

Oscillators Procurement Notes

Verify that the specific ordering suffix matches the required frequency tolerance and temperature grade, as variations exist within the EC36 family. Confirm the package dimensions align with the PCB footprint, specifically the 5.0 mm x 7.0 mm ceramic SMD outline. Ensure the design accounts for the 3.3 V supply requirements and the tri-state pin configuration during schematic capture. Cross-reference the manufacturer datasheet for reflow soldering profiles to prevent thermal damage during assembly.

Oscillators Selection Notes

Select this component when a 100 MHz clock source is required for high-speed digital interfaces like PCIe or Gigabit Ethernet. The LVCMOS output is suitable for direct connection to most modern FPGAs and microcontrollers without additional buffering. Consider the industrial temperature range (-40°C to +85°C) if the application involves harsh environmental conditions. Evaluate power consumption against system budgets, noting that higher frequencies in this series may draw increased current compared to lower-frequency variants.

Oscillators Part Context

This oscillator belongs to the EC36 series of standard quartz crystal oscillators produced by Ecliptek. The series offers various frequencies and stability grades in standardized surface-mount packages. The EC3645ETTTS variant specifically denotes the 5x7mm ceramic package with tri-state capability. This series is widely used in telecommunications and industrial automation where reliable timing is critical for data integrity and synchronization across multiple components.

Oscillators Replacement Considerations

Direct substitutes include other 100 MHz LVCMOS oscillators in 5x7mm packages from manufacturers like Abracon or SiTime, provided they match the pinout and electrical specifications. Verify that any replacement maintains the same tri-state control logic and operating temperature range. Check for compatibility with existing PCB footprints and ensure the new component meets the same RoHS compliance standards.
