Procurement Notes
Verify the specific frequency tolerance and operating temperature range against the official product datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design requirements. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.
Selection Notes
Select this component when a precise 10.3861 MHz clock source is required with low voltage operation. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the enable/disable feature if power efficiency is critical. Verify thermal performance within the specified operating range for the intended application environment.
Part Context
This part belongs to the QuikXO series of fast-delivery CMOS output clock oscillators from Mercury Electronics. The series offers various frequencies within a standard package format. The 18QHTF21 designation indicates the specific series and package type, while the suffix denotes the exact frequency and voltage configuration.
Replacement Considerations
Direct substitutes must match the 10.3861 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify electrical parameters such as phase noise and jitter against the original specification to ensure functional equivalence in the target circuit.
