EC5645ETTTS-30.000M TR

Oscillators Overview

The EC5645ETTTS-30.000M TR is a standard clock oscillator manufactured by Ecliptek, operating at a nominal frequency of 30 MHz with LVCMOS output format. It functions on a fixed 3.3 VDC supply voltage and maintains a frequency stability of ±50 ppm across the industrial temperature range of -40°C to +85°C. The component utilizes a compact 2.0 mm x 2.5 mm SMD package and supports a maximum load capacitance of 15 pF. Key electrical characteristics include a maximum RMS phase jitter of 1 ps within the 12 kHz to 20 MHz offset range, a start-up time of 10 ms, and a duty cycle of 50% ±5%. It features a three-state control pin for power management.

Oscillators Procurement Notes

Verify that the specific part number matches the required frequency and package dimensions before ordering. Confirm that the supplier provides official datasheets confirming the ±50 ppm stability covers all environmental factors including aging and voltage variations. Ensure compatibility with 3.3V logic levels and check that the three-state control pin configuration aligns with your circuit design requirements.

Oscillators Selection Notes

Select this component when a small footprint and industrial temperature range are critical. It is suitable for applications requiring low phase jitter and fast start-up times. Consider the three-state feature if power conservation during idle periods is necessary. Ensure the driving circuit can handle the specified load capacitance without signal degradation.

Oscillators Part Context

This oscillator belongs to the EC5645ETTTS series of standard SPXO components designed for industrial applications. It shares similar packaging and electrical characteristics with other frequencies in the family, such as the 7.3728 MHz and 14.31818 MHz variants. The series is characterized by its robustness against mechanical shock and vibration, making it appropriate for demanding environments.

Oscillators Replacement Considerations

Direct substitutes within the same series include EC5645ETTTS-7.3728M TR and EC5645ETTTS-14.31818M TR, provided the frequency difference is acceptable. Cross-brand replacements must match the 2.0x2.5mm package, 3.3V supply, and ±50 ppm stability specifications.

Oscillators FAQ

How is the three-state control implemented?

Pin 1 controls the output state. Applying a voltage above 90% of Vdd or leaving it floating enables the output. Applying a voltage below 10% of Vdd disables the output, entering a high-impedance standby mode.

What is the maximum RMS phase jitter specification?

The maximum RMS phase jitter is 1 ps, measured within the frequency offset range of 12 kHz to 20 MHz.
