Oscillators Procurement Notes

Verify that the specific part number matches the required ±45 ppm stability grade, as the EC27 series offers multiple tolerance options. Confirm the 2.5V supply voltage requirement aligns with the system power design. Ensure the 7.0x5.0mm footprint matches the PCB layout. Check for RoHS compliance documentation if exporting to regulated markets. Validate the enable pin circuitry supports the high-impedance disable state.

Oscillators Selection Notes

Select this model when a 25 MHz clock source with ±45 ppm stability is required for industrial environments ranging from -40°C to +85°C. It is appropriate for designs utilizing 2.5V logic families requiring LVCMOS outputs. Consider the enable feature for power-sensitive applications. Compare against other EC27 variants if different stability grades or supply voltages are needed. Ensure the 4-pin SMD package fits the available board space constraints.

Oscillators Part Context

This component belongs to the Ecliptek EC27 series of standard XO oscillators. The series provides various frequency and stability options in compact surface mount packages. The EC2745ETTS variant specifically targets applications needing moderate stability at 25 MHz with a 2.5V supply. It serves as a primary clock reference for microcontrollers, memory, and communication interfaces in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes within the same family include EC2725ETTS-25.000M TR (±25 ppm) and EC27100ETTS-25.000M TR (±100 ppm). Cross-brand replacements must match the 2.5V supply, LVCMOS output, 7.0x5.0mm footprint, and -40°C to +85°C temperature range. Verify equivalent jitter performance and start-up times before substitution.
