Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics to validate electrical characteristics and reliability standards for your specific application environment.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS output. The enable/disable feature makes it suitable for applications needing dynamic power control. Consider the small 2.0x1.6 mm package size for space-constrained designs. Verify that the 18.87436 MHz frequency meets the timing requirements of the target digital logic or communication protocol.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. Mercury Electronics is a Taiwan-based manufacturer specializing in frequency control products since 1973. This specific model represents a standard XO variant within their portfolio, distinguished by its 1.8V operation and enable pin configuration.

Oscillators Replacement Considerations

Direct substitutes must match the 18.87436 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Check for equivalent enable/disable functionality. Verify thermal and electrical specifications against original datasheets.
