Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design specifications. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no lead footprint matches the PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet before finalizing procurement.

Oscillators Selection Notes

Select this component when a precise 35.0208 MHz clock source is required with low power consumption. The LVCMOS output is suitable for standard digital logic families. Consider the 1.8V supply requirement and standby feature for power-sensitive designs. The small form factor makes it appropriate for space-constrained portable or industrial electronics where surface mounting is preferred.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standardized 4-SMD package. The series typically includes options like 51.2 MHz and 96.768 MHz, maintaining consistent electrical characteristics and physical dimensions across different frequency variants for design flexibility.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts such as 18QHTF21-51.200-PD or 18QHTF21-96.768-PD if frequency adjustment is permissible. Cross-brand replacements require matching LVCMOS output, 1.8V supply, and 4-SMD no lead package dimensions.
