EC2625ETTS-66.666M TR

Oscillators Overview

The EC2625ETTS-66.666M TR is a CMOS quartz crystal clock oscillator (XO) manufactured by Ecliptek. It operates at a nominal frequency of 66.666 MHz with an LVCMOS output format. The device requires a 3.3Vdc supply voltage and features a 4-pad ceramic surface mount package measuring 5.0mm x 7.0mm. Key electrical specifications include a frequency tolerance of ±25ppm, a maximum operating temperature range of -10°C to +70°C, and a maximum aging rate of 5 PPM/year. The output duty cycle is specified as 50% ±10%, with a maximum rise time of 3ns.

Oscillators Feature Summary

• Features a tri-state control function on Pin 1 for enable/disable operations, allowing high impedance states to reduce power consumption during standby modes.
• Utilizes a robust ceramic surface mount construction designed for reliable performance in industrial environments across the specified temperature range.
• Provides stable LVCMOS clock signals suitable for driving digital logic interfaces without requiring additional buffering components.

Oscillators Applications

• Industrial gateway reference clock systems
• High-speed data communication equipment timing
• Consumer electronics requiring precise clock synchronization

Oscillators Procurement Notes

Verify that the specific ordering suffix matches the required frequency tolerance and temperature range, as variations exist within the EC26 series. Confirm RoHS compliance status and lead-free certification requirements for your assembly process. Ensure the tape and reel packaging aligns with your automated pick-and-place equipment specifications. Cross-reference the manufacturer part number with distributor catalogs to confirm current availability and active status before finalizing procurement plans.

Oscillators Selection Notes

Select this component when a 66.666 MHz clock signal is required with strict ±25ppm stability over the -10°C to +70°C range. The 5x7mm ceramic package offers a balance between thermal stability and board space efficiency compared to smaller packages. Consider the tri-state feature if system power management requires clock gating capabilities. Ensure the load capacitance requirements match the downstream circuit design, typically supporting up to 15pF.

Oscillators Part Context

This oscillator belongs to the EC26 series from Ecliptek, which provides standard clock solutions for various digital applications. The series includes variants with different frequencies, supply voltages, and temperature ranges. The EC2625ETTS model specifically denotes the 3.3V operation and ceramic package type. Similar models like EC2625TS or EC2645ETTS may offer different form factors or extended temperature ratings.

Oscillators Replacement Considerations

Direct substitutes within the same family include EC2625TS-66.600M TR for slightly different frequency requirements. For broader compatibility, verify equivalent oscillators from Abracon under the EC36 series, though package dimensions and pin configurations must be checked carefully. Always validate electrical parameters against the original datasheet before swapping components in existing designs.
