Oscillators Procurement Notes

Verify that the specific part number suffix matches the required tape and reel packaging configuration. Confirm that the operating temperature range aligns with the environmental conditions of the target application. Ensure compatibility with the 3.3V power supply rail and check that the load capacitance requirements are met by the circuit design.

Oscillators Selection Notes

Select this component when a 66 MHz clock source with ±50 ppm stability is required within a -10 °C to +70 °C range. Consider the 5x7mm footprint for board space constraints. Verify that the LVCMOS output voltage levels match the input thresholds of the receiving logic circuits. Evaluate the tri-state functionality needs for power management strategies.

Oscillators Part Context

This oscillator belongs to the EC2645 series, which includes various frequency options and package variants. The series is characterized by RoHS compliance and lead-free construction. It serves as a direct replacement for previous generations of standard oscillators in similar form factors, maintaining consistent electrical performance standards across the product line.

Oscillators Replacement Considerations

Direct substitutes include other EC2645 series variants with different frequencies but identical packages, such as EC2645TTS-33.333M TR. Cross-brand replacements must match the 5x7mm footprint, 3.3V supply, and LVCMOS output specifications.

Oscillators FAQ

How does the tri-state pin function operate?

Pin 1 controls the output state. A low voltage level disables the output, placing it in a high-impedance state, while a high voltage level enables normal operation.

What is the maximum frequency stability specification?

The maximum frequency tolerance and stability is ±50 ppm, inclusive of calibration tolerance, temperature drift, aging, and other operational conditions.
