Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the enable pin logic levels are compatible with your microcontroller or FPGA outputs to guarantee proper operation.

Oscillators Selection Notes

Select this component when a low-profile, 1.8V LVCMOS oscillator is required. Consider the 2.0x1.6 mm footprint for PCB layout constraints. Evaluate the enable feature necessity for power-sensitive designs. Compare performance metrics such as phase noise and jitter if high-frequency stability is critical for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies and supply voltages. The 'OE' suffix may indicate specific packaging or testing options compared to other variants like 'PD'. Check the full datasheet for detailed electrical characteristics and reliability data.

Oscillators Replacement Considerations

Direct substitutes must match the 22.577 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other Mercury Electronics models in the same series for potential drop-in replacements.
