Oscillators Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration when placing orders. Confirm that the 2.5V supply voltage requirement aligns with the target system's power rails. Ensure the ceramic SMD footprint matches the PCB layout dimensions. Check for RoHS compliance documentation if environmental regulations apply to the final assembly. Validate the enable/disable pin configuration against the circuit design requirements.

Oscillators Selection Notes

Select this component when a 125 MHz LVCMOS clock source is required with low voltage operation. Consider the 3.2mm x 5.0mm package size for space-constrained designs. The enable/disable feature makes it suitable for applications needing dynamic clock gating. Compare frequency stability specifications against other series options if tighter tolerance is needed. Ensure the operating temperature range meets the environmental conditions of the intended deployment.

Oscillators Part Context

This oscillator belongs to the EC2745 series of quartz crystal oscillators from Ecliptek. The series offers various frequencies and package sizes tailored for different embedded applications. The EH36 and EC27 series share similar LVCMOS output characteristics but differ in voltage and package dimensions. This specific model provides a balance of speed and power efficiency for mid-range digital applications.

Oscillators Replacement Considerations

Direct substitutes may include models from the same EC2745 family with adjusted frequency or voltage ratings. Cross-reference with EH36 series devices if 3.3V operation is acceptable and package compatibility allows. Verify pinout and electrical parameters before swapping to ensure functional equivalence in the host circuit.
