EC2700TS-25.000M TR

Oscillators Overview

The EC2700TS-25.000M TR is a standard quartz crystal oscillator (SPXO) from the EC27 series, manufactured by Ecliptek. It operates at a nominal frequency of 25 MHz with an LVCMOS output format. The device requires a 2.5V supply voltage and features a 4-pin surface-mount ceramic package measuring 7.0mm x 5.0mm. Key electrical specifications include a total frequency stability of ±100 ppm across all conditions, including calibration, temperature drift, voltage variation, load changes, aging, and vibration. The operating temperature range is -10°C to +70°C. RMS phase jitter is specified as 1 ps within a 12 kHz to 20 MHz offset bandwidth. The component supports tri-state control for enable/disable functionality and complies with RoHS and REACH standards.

Oscillators Feature Summary

• Provides stable clock signals with integrated tri-state control for power management via pin configuration.
• Delivers comprehensive frequency stability metrics that account for environmental and operational variances.
• Features low phase jitter suitable for general digital communication and microcontroller applications.
• Constructed in a compact ceramic SMD package designed for automated surface-mount assembly.

Oscillators Applications

• Clock source for industrial data acquisition gateways
• Timing reference for microcontroller unit (MCU) systems
• Clock generation for Ethernet PHY interfaces
• Power supply for low-power battery-operated devices requiring standby modes

Oscillators Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm the operating temperature grade matches the application requirements, as this model specifies a -10°C to +70°C range. Ensure the design accommodates the 2.5V supply voltage and includes necessary decoupling capacitors near the power pin as recommended in the datasheet. Check for compliance with RoHS 2.0 and REACH regulations if exporting to restricted regions.

Oscillators Selection Notes

Select this component when a 25 MHz clock signal is required with moderate stability needs. It is suitable for applications where power consumption must be managed through a tri-state enable function. Consider this part for designs constrained by the 7x5mm footprint. Evaluate the ±100 ppm total stability against system timing tolerances. Compare against higher-stability options like TCXOs only if jitter or drift exceeds the 1 ps RMS specification.

Oscillators Part Context

This oscillator belongs to the EC27 series, which offers various frequency and stability options in a standardized 4-pin SMD form factor. The series is designed for general-purpose timing applications in consumer and industrial electronics. Ecliptek manufactures these components using lead-free processes. The product line emphasizes ease of integration with standard CMOS logic families and provides consistent performance across the specified commercial temperature range.

Oscillators Replacement Considerations

Direct substitutes within the same series include models with different frequency tolerances such as ±20 ppm or ±25 ppm variants, provided the package and voltage remain compatible. Cross-reference with other manufacturers offering 7050 package SPXOs at 25 MHz with similar jitter and stability specs. Verify pinout compatibility, specifically the tri-state control on Pin 1, before replacing.

Oscillators FAQ

How is the tri-state control implemented?

Pin 1 controls the output state. Connecting it to VDD or leaving it floating enables the output. Connecting it to GND disables the output, placing it in a high-impedance state and reducing current consumption to approximately 10 μA.

What does the ±100 ppm stability rating include?

The ±100 ppm figure represents the total frequency deviation inclusive of initial calibration tolerance at 25°C, frequency stability over the operating temperature range, supply voltage changes, load variations, first-year aging, and mechanical shock/vibration effects.
