Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the Enable/Disable pin configuration matches your control logic. Check the 4-SMD No Lead footprint dimensions for PCB layout compatibility to ensure proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required for timing applications. The LVCMOS output is suitable for standard digital logic families. Consider the enable/disable feature if power conservation or dynamic clock gating is necessary. The small form factor makes it appropriate for space-constrained designs. Verify that the 38.57143 MHz frequency meets the specific data rate or clock division needs of the target application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The 'OE' suffix typically indicates a specific packaging or tape-and-reel configuration, though exact details require datasheet confirmation. This series is designed for reliable performance in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 38.57143 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify equivalent electrical characteristics such as phase noise and jitter specifications. Ensure the replacement part supports the same enable/disable control mechanism. Cross-reference pinout configurations to guarantee compatibility without PCB redesign.
