Procurement Notes
Verify the specific frequency tolerance and stability requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper assembly and electrical connection.
Selection Notes
Select this component when a 13.534 MHz clock source is required with LVCMOS outputs. Consider the 1.8V operating voltage constraint during system design. Evaluate the need for enable/disable control features for power optimization. Compare package dimensions against available board space constraints.
Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Ind., Co., Ltd. The series offers various frequencies within a standardized 2.0x1.6mm SMD form factor. Other variants in the family share similar electrical characteristics but differ in output frequency and potentially tolerance specifications.
Replacement Considerations
Direct substitutes include other 13.534 MHz XO components with LVCMOS outputs and 1.8V operation in a 4-SMD package. Verify pinout compatibility and thermal characteristics when considering alternative manufacturers.
