Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Confirm that the 1.8V supply rail stability meets the oscillator's operational needs. Ensure the PCB layout accommodates the 2.0x1.6mm footprint and 4-SMD no lead package geometry. Check for any specific handling instructions regarding electrostatic discharge protection during assembly.

Selection Notes

Select this component when a precise 13.4 MHz reference is required for LVCMOS compatible circuits. Consider the 1.8V supply constraint and the necessity for power-down capabilities. Evaluate the thermal performance within the -40°C to 85°C range against environmental conditions. Compare the physical size constraints with alternative packages if space is limited.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The suffix PD indicates the inclusion of power-down features. The series is designed for applications requiring stable timing in compact form factors.

Replacement Considerations

Direct substitutes must match the 13.4 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no lead package. Verify pin compatibility and electrical characteristics. Consult manufacturer cross-reference lists for equivalent parts.
